I. Introduction

A. Geographical Features of the Brantas River Basin

Brantas River Basin is located in the Island of Java, of the Republic of Indonesia. It runs through the western section

of the East Java Province. The basin is situated from Latitude 7o 1’ to 8

o 15’ South and Longitude 110

o 30’ to 112

o 55’

East. The river mainstream traverses 9 regencies and 5 municipalities. Starting at the upper regions of the river they

are Malang, Blitar, Tulungagung, Kediri, Nganjuk, Jombang, Mojokerto, Sidoarjo, and Surabaya City, including

portions of Pasuruan and Gresik. A general view of the Brantas River Basin is shown in Figure 1.

Volcanoes within the Brantas Basin are Mount Arjuna (3,339 m), Mount Anjasmara (2,282 m), Mount Butak (2,868

m), Mount Kawi (2,651 m), Mount Kelud (1,724 m), Mount Semeru (3,676 m), and others. Mount Semeru is

constantly active. In this century, Mount Kelud has erupted on a large scale an average of once every 15 years: 1901,

1919, 1951, 1966, and 1990. The total volume of ejecta is estimated at 100-200 million m³, having a decisive effect

on local society as well as the environment.

The Brantas River is characterized by clockwise watercourse centering on Mount Kelud. This is influenced by the

process of mountain uplift and the volcanic ranges. The Brantas originates from the southeastern side of Mount

Anjasmara located in the center of its basin. The uppermost stream starts its course eastward south around the

Semeru volcanic zone, and the runs to the west parallel to the Southern Mountains, which stretch east and west

blocking the river’s course. It changes its course again to the north to avoid older volcanoes and Mount Wilis, and

the runs past the foot of Mount Wilis and Mount Kelud to reach Surabaya City. Thus the Brantas travels past all the

major volcanic ranges in the basin.

B. Physical and Social Features of the Brantas River Basin

The population in the basin in 2006 (13,480,000) was more than twice that of 1960 (8,370,000), shortly

after the Brantas River Basin Development Project started. Surabaya City alone showed a remarkable

increase of 2.27 times compared to the 1.84 times of Java Island during the same period. This is good proof

of Surabaya’s rapid growth as a commercial and industrial city. With a population of 2.938.225 as of 2009,

Surabaya is the biggest commercial and industrial city next to Jakarta. Also, being a port city equipped with

modern facilities, it serves as a hub of domestic trade. With the availability of a plentiful labor force, the

Brantas River Basin around Surabaya City has become industrialized and urbanized, thereby creating a sharp

increase in economic activities.

The average specific runoff of the Brantas River (average runoff per 100 km²) is 3,4 m³/sec at the Sutami Dam on the

upper river, and 2,7 m³/sec at Jabon on the lower river. Evaporation of the Brantas River basin varies from 2.4

mm/day in January to 4.3 mm/day in August . From the comparison of specific runoff among the Brantas and major

rivers of the world, it follows that generally the runoff percentage of small and medium scale Indonesian rivers show

trends similar to that of rivers in Japan, whereas large river such as Solo and Brantas tend to have the same

characteristics as those in Asia, relating to high evaporation.

Rice yield in the Brantas Basin 1965 was 1,107 million tons. It went up to 2,299 million tons in 2004 even though

there was only a slight increase in paddy field area. A comparison between 1965 and 1993 yields shows that the rate

of increase in the Brantas Basin was 2.33 times in contrast to 2.29 times for the entire country. This can be said to be

a direct result of advanced intensive agricultural methods, based on the availability of irrigation water in the dry

seasons.

The rice yield per unit area was 4.54 tons/ha on the national average as of 2004, showing a considerable increase

from 3,48 tons/ha in 1965. The yield for the Brantas basin was 3.69 tons/ha in 1965 and 5.48 t/ha in 2004, well

beyond the national averages. This was due to improvement of rice varieties, introduction of chemical fertilizers, and

an increase in double cropping made possible by secured irrigation water in dry season.

The installed capacity for power generation was 13,600 MW as of 1993. of these, hydroelectric power generation

makes up, 2,179 MW, 16.0% of the total installed capacity for power generation. The total installed capacity in East

Java is 3,682 MW; of which 275 MW are hydroelectric. The installed capacity for hydroelectric power generation in

the Brantas Basin is 263 MW, which are 12.3% of the total in Indonesia and 97.8% of that in East Java for

hydroelectric power plant.

The electrification ratio in villages reached 54.7% in 1993 at the end of the fifth 5-year development plan. In the

sixth plan, the policy «further efforts for power development» was presented with a target value of 79%. The

electrification ratio on Java Island was 76.1% as of 1993, exceeding the national average of 54.7% by over 11%. The

Brantas Basin was among the areas on the island with the highest electrification ratio, being 15% in 1970 and more

than 85 % in 1993 and 90% in 2005.

C. Water Resources Development in the Brantas River Basin

Water resources in the Brantas River Basin have been developed since almost 1,200 years ago. However modern

development in water resources took place just as early as the end of the 19th

century introduced by the Dutch for

agricultural purposes. Comprehensive water resources development in the Brantas River Basin was introduced after

the Indonesian Government requested the preparation of a water resources development scheme as part of war

reparation assistance undertaken by Japanese Government after the Second World War.

The plan was carried out based on One River, One Plan, One Integrated Management principle, and initially prepared

for the Brantas River Basin in a so called Brantas Plan (1958) that was fortified into the ever first master plan of the

Brantas River Basin in 1961. This initial master plan was then periodically reviewed in order to update the plans in

accordance to the national development requirements. In sequence the following plans were undertaken in the

basin:

1. Master Plan I prepared in 1961, emphasized on flood control by developing dams at the upper reaches and

river improvements in the middle and lower reaches to increase flood relief capacity.

2. Master Plan II was prepared in 1973 emphasizing on irrigation development to support the government

policy on food sustainability by developing dams, barrages and technical irrigation schemes.

3. Master Plan III was prepared in 1985 emphasizing on water supply for domestic and industrial uses to

support the government policy on industrialization by developing new dams.

4. Master Plan IV was prepared in 1998, emphasizing on conservation and effective water resources

management to face the environment problems and challenge on the implementation of effective water

governance.

Total development in the basin resulted into 8 (eight) reservoirs (Sengguruh, Sutami, Lahor, Wlingi, Lodoyo, Selorejo,

Bening and Wonorejo), four river-improvement-schemes, four barrages, and three rubber dams etc. All of these

structures and their purposes can be seen in the following Table 3. The development of the Brantas River Basin is a

comprehensive multipurpose project, which uses dams, and reservoir for development of water resources, resulting

benefits in flood control, irrigation, and power generation, domestic and industrial water supply.

Multipurpose dams were constructed in the upper reaches, flood control of which could be used to decrease the

flood run off in the lower reaches. Around 1958, when the Brantas River Basin Development was commenced, debris

produced by the eruption of Mt. Kelud caused the agradation of riverbed of the Brantas River and its main

tributaries. This sediment deposition decreased the river discharge capacity for carrying flood. This incurred flooding

almost every year, resulting in personal injury, crop damage and loss of asset. Accordingly, flood prevention was

given a top priority in the initial stages of the development (Master Plan I, 1961), reviewed in 1973 (Master Plan II)

and renewed in 1985 (Master Plan III).

D. Main Issues and Expected Challenges for the Future in Managing Water in the Brantas River Basin

Some issues are identified as the most likely to have significant impacts on future water management in the Brantas

Basin. The issues and challenges will give impact to water security in the basin, since water resources in the basin is

very important input of agriculture production, water quality degradation has occurred in the basin and threaten the

health and welfare of the poor and the water related hazards such as extreme floods and landslides etc happen

frequently.

The first main issue and challenge is related to water scarcity in the Brantas River basin in the near future that will

cause the difficulties to allocate water due to increasing water demand and limited supply capacity. This situation

will lead to conflict of interest among users. The limited supply capacity is caused by the decrease of effective

storage capacity of the reservoirs in the basin due to severe land erosion and sedimentation. Watershed degradation

has become an important constrain, since erosion (related to land use and spatial management) and natural forces

(volcanic debris) enhances sedimentation that shortens economic life of major dams in the basin and natural base

flow degradation during dry spells.

Page 7: 9_TJOEK WALUJO SUBIJANTO_PAPER

7

The Brantas River basin has eight reservoirs with a total initial gross storage capacity of 647.0 million m3 and

effective storage capacity of 479.6 million m3. Because of sedimentation, the gross and effective storage are now

decreasing to 390 million m3 (60%) and 341 million m

3 (71%) respectively. This situation will be in risk considering

the impact of global climate change on water resources i.e. the increase of frequency and magnitude of drought.

The second main issue and challenge is related to water quality deterioration in the Brantas River basin. Increase of

population at the Brantas River Basin and various economic activities, has direct impact on water quality in the

basin, and could be foreseen in the following facts:

1. Domestic bulk water supply for Surabaya City is provided mainly from Brantas surface water. As a matter of

pollution accumulation, the river’s water has a low dissolved oxygen (DO) level, thus creating water

purification difficulties and rises the cost of water treatment.

2. Increased water pollution are frequently worsen by shock loadings, especially in the dry season when natural

flows in the rivers are at the minimum.

3. The occurrence of increased turbidity during the rainy season inflicts the increase of sediment contents

caused by degradation of the upstream catchments area.

4. Eutrofication symptoms at the Sutami Reservoir caused by the accumulation of nitrates (N) and phosphates

(P) elements. This symptoms creates significant problems, like: algae blooming, deterioration of freshwater

fauna and organic depravement.

The third main issue and challenge is related to water related hazards in the Brantas River basin. The water related

hazards such as extreme floods and landslides etc happen frequently in the Brantas River basin due to climate

change impact. Extreme flood usually happen in some small tributaries e.g. Amrong, Bogel, Sadar, Batan, Gunting

Rivers etc. The flood occurrence in the tributaries couldn’t be avoided due to lack of flood control structures.

Big flood happened in some small tributaries in the Brantas River basin in December 2007 due to extreme rainfall

that took place simultaneously and intensively in whole basin started on December 24, 2007 at 09.00 AM until

December 26, 2007 having duration of about 64 hours. In upper reach of Brantas River basin and Sutami Lahor sub

basin, cumulative rainfalls of about 192 mm for 23 hours was recorded at Poncokusumo Station, about 196 mm in 38

hours at Pujon Station, about 578 mm in 32 hours at Dampit Station, and 372 mm in 24 hours at Sengguruh Station,

and the highest discharge of about 1,582 m3/s and 750 m

3/s were recorded at Gadang Station and Tawangrejeni

Station, respectively. Maximum inflow discharge to Sengguruh reservoir was recorded of about 1,422 m3/s at that

time. Recorded maximum inflow discharge in Sutami Reservoir, the largest reservoir in Brantas River basin, located

in the downstream of Sengguruh Reservoir, was about 1,434.5 m3/s that could be controlled by the reservoir.

Accordingly, water level of Sutami Reservoir increased 10.10 m in 36 hours, from elevation + 262.12 m on December

25, 2007 at 12:00 to elevation +272.22 m on December 27, 2007 at 00:00.

E. Progress in Improving Water Security in in the Brantas River Basin

1. Institutional Aspect of Water Resources Management in the Brantas River Basin

The water resources sector administration system in Indonesia is governed under two systems: (a) a de-concentrated

public administration system, and (b) a decentralized public administration system. Under the de-concentrated

system the Governors and Regents act as regional representatives of the President and implement central

government policies and programs under the supervision of the Central Government. While the regions are

consulted on the programs, it is left to the center to decide on the size, scope, and implementation modalities.

The dinas agencies operate under the regional governments and conform more or less exactly to the central

implementing ministry and function as a line agency for deconcentrated activities. For example, the «centralized»

Ministry of Public Works (MPW), which has a Director General for Roads, Human Settlement and Water Resources,

has a counterpart in a region (Province/Regency) known in Indonesian as Dinas Pekerjaan Umum (abbreviated as

Dinas PU) in the areas of Road Transportation (Dinas Bina Marga), Human Settlement (Dinas Cipta Karya), and

Water Resources (Dinas Pengairan). While the Dinas PU organization is part of regional government structure, the

centralized Ministry of Public Works technically guides them. For all de-concentrated activity, the regional Dinas

agencies work under the supervision and guidance of the respective central ministries. The Dinas PU agencies

manage their functions through branch offices known as Cabangs or UPTDs (Unit Pelaksanaan Teknis Daerah or Unit

for Technical Management). In the case of the water sector, the provincial Dinas PU Pengairan (Provincial Water

Resource Agency) has – beginning in 1998, gradually replaced the field offices (Cabangs) with Balai PSDAs (Basin

Water Resource Management Units) which are a form of Unit for Technical Management (UPTD).

In the pre-year 2000 public administration system, most decentralized functions in the water sector public services

were limited to operation and maintenance-type activities and its management, while almost all development

activities were handled as centralized, deconcentrated activities. A limitation in decentralized decision-making has

been the lack of regional autonomy and authority and regional resource constraint. With the enactment of the

autonomy and fiscal decentralization laws in 1999 and its revision in 2004, more and more sectoral activities and

programs are expected to be handled under the decentralized approach. Also, the unitary system of government

with central control has so far inhibited decision-making at the appropriate level. This is expected to improve as

autonomy laws begin to be implemented.

Until 1998 all aspects of water resource management in the Brantas River Basin were managed by a dual system of

management. The center through DGWR and its projects was responsible for most developmental activities while a

river basin corporation (PJT-I), a corporate-type RBO, managed the infrastructure on behalf of the central ministry

under the Government Regulation No. 93 of 1999. The provincial government through its Provincial Water Resource

Agency (Dinas PU Pengairan) and field offices exercised the regulatory role of water abstraction licensing, sand

mining licensing, land use licensing, water quality regulation, and O&M of all irrigation systems in the river basin.

The PJT-I act as a bulk water operator and a monitor of all water withdrawals. The regency level agencies had no

direct authority in basin water management including irrigation or its development except in land use area.

The local level inputs were solicited either through normal administrative channels or through coordinating

committees such as the Regency Irrigation Committee (Panitia Irigasi Kabupaten) and Provincial Irrigation

Committee (Panitia Irigasi Provinsi).

There are a number of agencies, both structural and non-structural (project status), that are involved either fully or

partially and directly or indirectly in water resource related functions in the basin. In 1998 a study lists 35

organizations that have a role in water resource development and management. It also lists the tasks and duties of

these organizations in water resources management.

basin

The concept of ad hoc bodies, comprised of representatives from related agencies from all levels (for example, a task

force for water quality management, flood management, watershed management), was used to provide

recommendations to the provincial or central authorities to act upon. Stakeholder input was mostly through a

consultative process, and formal representation in committees and task forces was limited to government agencies

such as forestry, agriculture, industry, environment agencies. Much of the water resource functions were

undertaken directly by the center or by the province through the deconcentration principle. Only irrigation

management functioned on the decentralization principle at the provincial level with the farmer’s organization

(WUA) treated as objects rather than subjects.

The country’s democratization process that began in 1998, resulting in the laws on decentralization and autonomy to

regencies in 1999, has now created the necessary environment for basin water management activities to be

decentralized to the appropriate levels of administration. This process has started and with the completion of the

water sector reform in the near future will decide on how decentralization will function.

Existence of PJT-I in the Brantas River Basin as a government owned company with responsibilities of conducting

operation and management activities as well as rendering water services is secured. Typically in the Brantas River

Basin there are two type RBOs, first one is PJT-I with responsibility of: (1) operation of the water resources

infrastructures; (2) conducting preventive maintenance, including to a certain extent periodical rehabilitation; and

(3) rendering water services to the users under the cost-recovery scheme. On the other hand, there is also a public-

type utility RBO, or Balai Besar Wilayah Sungai, which is a transformation of the former «project-type unit» under

the MPW, namely the Brantas River Basin Development Project. Establishment of this public-type utility RBO was

initiated by the Regulation of the Ministry of Public Works No. 12/PRT/M/2006.

Thus, in the Brantas River Basin could be found two types of RBOs with different responsibilities. In order to avoid

overlap in undertaking its responsibilities, a specific clear cut was drawn where it is commonly agreed that PJT-I as a

corporate-type RBO undertakes separate responsibilities than the public-type utility RBO. Both RBOs will focus on

water resources management within the confined terms of a river basin as drawn in the Water Law of 2004, but with

different performing areas of responsibilities.

The main organizations that have a role in water resource development and management are The East Java Water

Resources Service Office, Jasa Tirta I Puboic Corporation, the Brantas River Basin Public Utility Organization and the

Water Resources Management Coordination Team.

The East Java Water Resources Service Office manages water through agencies that were set up in 1998 (on the

transfer of the provincial field offices) as part of decentralizing basin water resources management from the center

to the provinces and basin. These agencies operate, maintain, and manage the infrastructure and the water

resources in the rivers that are not under the jurisdiction of PJT-I. They manage mostly the second, third, and fourth

order rivers (around 1,510 rivers) in the Brantas River basin that do not have major infrastructure or do not have

major water benefits except irrigation. These agencies manage the inter-district irrigation system and acts more as

field regulatory arm of the East Java Water Resources Office. These agencies are the lowest level agency where

input for regulatory decisions (abstraction licensing, effluent discharge licensing, flood plain use, etc.) is made.

Agencies act as the field offices of the East Java Water Resources Office and provide the operational support.

PJT-I was established in 1990, based on Government Regulation No. 5 of 1990 (ad later replaced by Government

Regulation No. 93/1999 to strengthen the organization and permit its jurisdiction to extend to other basins), is

charged with managing the water resources in 40 of the more important benefit producing rivers (including the

Brantas River) of the basin and to operating, maintaining, and managing the major infrastructure in these rivers.

Detail explanation on PJT-I will be available in the next section of this part.

The third important institution in the Brantas River Basin is the Brantas River Basin Public Utility Organization. This

organization was established by the Ministry of Public Works decree No. 248/KPTS/M/2009 on February 9, 2009.

This organization is entitled with various responsibilities, basically representing government obligation for public

services, like rehabilitation of water resources infrastructures and construction of new infrastructures.

The fourth organization is the Water Resources Management Coordination Team consists of river basin organizations

in the basin (Jasa Tirta I Public Corporation and Brantas River Basin Public Utility Organization or in Indonesian: Balai

Besar Wilayah Sungai Brantas), Provincial and Regency/Municipal Government Agencies (agencies related to

regional planning, water resources, agriculture, environment, health, forestry, transportation, industry, energy and

natural resources, coastal and fishery, education, etc) and non-governmental organizations (consist of water users

organizations/associations for irrigation, domestic use of water and industries, electricity, forestry, etc).

Prior to the establishment of the Coordination Team of Water Resources Management in Brantas River basin, in

order to avoid conflict among water users in the Brantas River basin, a Provincial Water Resources Management

Committee (in Indonesian: Panitia Tata Pengaturan Air abbreviated as PTPA) was established based on the East Java

Governor’s Decree No. 59 of 1994. The committee, which was responsible to the Governor, was supposed to be a

coordination body where decision on all management aspects in water resources (planning, implementing,

supervising, controlling and funding) in its respective area was made.

2. Legal and Financial Arrangements

The Indonesian Water Law (Law No 7 of 2004 on Water Resources) enacted on March 2004 has given path to the

decentralization process of water resources at the basin level. The Law stipulates that certain authorities that lie in

the hand of the central government could be over handed to the provincial government or to a distinctive

organization within the river basin. Leading on this clause, water resources at a river basin level could be managed

either by the government or any third party that fits into the regulation to serve water resources responsibilities.

Following the enactment of Law No 7 of 2004 on Water Resources, some Government Regulations were issued to

support the implementation of the Law. One of the most important Government Regulations is the Government

Regulation No 42 of 2008 on Water Resources Management which stipulate keys aspects of water resources

development and management i.e. conservation, water resources utilization, controlling destructive forces of water

resources. For implementation in the field, some Governor Decrees and Provincial Government Regulations were

issued to support water resources management in the Brantas River basin. For example, there is East Java Governor

Provincial Government Regulation No. 10 of 2007 on licensing of water surface abstraction in East Java Province.

In the water sector most of the development-type activities are being undertaken as de-concentrated activities

under the central budget known as APBN while some of the smaller development activities are taken up as

decentralized activities. In general most operation and maintenance (O&M) and irrigation system management are

decentralized except for some major irrigation systems (for example, the Jatiluhur irrigation system of 240,000 ha)

and new or rehabilitated irrigation projects that have not been transferred to local government. Based on

Government Regulation No 20 of 2006 on Irrigation, irrigation area of more than 3,000 ha is managed by Central

Government, irrigation area of 1,000 - 3,000 ha is managed by Provincial Government and irrigation area of less than

1,000 ha is managed by Regencial Government.

So far most activities related to basin water resources management that are funded under APBN and are deemed to

be de-concentrated activities. However, elements of water resources management (hydrology measurement,

licensing of water abstraction, operation and maintenance of certain facilities, management of river infrastructure,

etc.) have been funded under APBD and thus follow the decentralized approach. In most cases the decentralized

activities (local decision and regional funding) in water sector either complements or supplements the

Page 11: 9_TJOEK WALUJO SUBIJANTO_PAPER

11

deconcentrated activities except in the case of irrigation system operation and maintenance. Most decentralized

activities are based on relevant centrally established policies, regulations, and guidelines.

As a corporate type river basin organization, PJT-I has been given the authority to collect water service fee from the

commercial beneficiaries – hydropower energy producers and bulk water consumers (including domestic as well as

industries). Budget for operation and maintenance of the basin infrastructures and water services, as well as

management and overhead costs (office) are borne by the revenue from these beneficiaries.

The implementation of policy on progressive tariff of water service fee has driven the efficiency of industrial water

use especially for sugar factories. The total volume of raw water used by sugar factories in the Brantas River basin

decreased significantly from 91.52 million m3 in 1992 to 65.53 million m

3 in 2009.

As the Water Law of 2004 exempts’ farmers, the biggest water consumer, for paying water service fee, however,

beneficiaries’ contribution has increased from 9.4 billion Rupiah in 1992 to 117.76 billion Rupiah in 2009 and

projected to increase 172.38 billion Rupiah in 2010. Fund collected from the water service fee is prioritized by PJT-I

to ensure operational continuity of the infrastructure, based on a balance budget, the remaining fund is spent on

preventive maintenance, periodical maintenance and minor repairs. For asset renewal, the Brantas River Basin relies

on the Balai Besar Wilayah Sungai or public-type utility RBO. This RBO is responsible for major repairs, rehabilitation,

rectification and special maintenances. However, due to the inflexibility on the financial aspect of this public-type

utility RBO (as it relies solely on the Government’s fund) it is possible for PJT-I to render emergency maintenance at

the river and its infrastructure whenever it is necessary.

However, as the infrastructure in the Brantas River Basin is already between 20-40 years old, thus more attention

needs to be given. Certain installment on the maintenance activities has provoked infrastructure damages. Japan

International Cooperation Agency (JICA) in 2001, estimated rehabilitation cost of these facilities to be close to 704

billions Rupiah.

3. Collaboration with Other Stakeholders (National/Local Governments, Committees, Communities, Donors,

NGOs)

As a platform for stakeholder liaison and an advisory body for water-related basin-level development and

management in the Brantas River basin, a coordinated team called the Coordination Team of Water Resources

Management in Brantas River basin which established based on Ministry of Public Works Decree No.

248/KPTS/M/2009 on February 9, 2009. The Coordination Team identifies development needs and opportunities,

provides policy guidance, and undertakes strategic development planning and implementation planning. The main

responsibility according to the Law on Water Resources (2004) is to formulate water resources policies and

strategies. The Council reports to the Minister of Public Works and to the Governors of Central Java and East Java

Provinces.

Membership of the Coordination Team consists 50% from Government and 50% from Non Government.

Memberships from Government consists of River Basin Organizations (Jasa Tirta I Public Corporation and Brantas

River Basin Public Utility Type RBO - Balai Besar Wilayah Sungai Brantas), Provincial and Regency/Municipal

Government Agencies (Agencies related to regional planning, water resources, agriculture, environment, health,

forestry, transportation, industry, energy and natural resources, coastal and fishery, education, etc). Memberships

from Government non Government Organizations consist of water users organizations/associations for irrigation,

drinking water, industry, fishery, electricity, tourism, forestry, etc.

Prior to the establishment of the Coordination Team of Water Resources Management in Brantas River basin, in

order to avoid conflict among water users in the Brantas River basin, a Provincial Water Resources Management

Committee (Panitia Tata Pengaturan Air/PTPA) was established based on the East Java Governor’s Decree No. 59 of

1994 on the Establishment of Water Resources Management Committee in East Java Province. The committee,

which was responsible to the Governor, was supposed to be a coordination body where decision on all management

aspects in water resources (planning, implementing, supervising, controlling and funding) in its respective area was

made.

Page 12: 9_TJOEK WALUJO SUBIJANTO_PAPER

12

The NGO movement in the water sector has been rapidly gaining momentum since the early 1990s. The NGO

movement in the water sector is in the environmental area and is primarily involved in social-watershed-pollution

aspects. A number of universities participate in the water sector decision making process through expert advice or

providing consultancy. The water sector reform process, which began in 1999, has generated interest in the policy

and legal aspects among some NGOs. The NGOs such as LP3ES and WALHI have played a major role in providing

input to the water sector reform movement and have conducted public consultation and surveys to solicit input from

stakeholders and the public.

In the Brantas Basin a number of NGOs and institutions participate in aspects of WRM (primarily environment

related) and work with the provincial and basin level agencies. But the NGOs have no institutional authority in

decision-making they are playing an important role in bringing public awareness, monitoring water quality, managing

solid waste and domestic sanitation, and promoting transparency in WRM activities. The NGOs such as Ecoton has

played a major role in conducting conservation of water quality and bio-diversity in the rivers.

To promote river health, PJT-I invites senior high school teachers to be involved by introducing awareness to water

and environment conservation to their students. Senior High Schools Communication Networks for Water Quality

Monitoring in the Brantas River Basin, East Java, Indonesia was established by PJT-I in cooperation with State

University of Malang and teachers from senior high schools in Brantas River Basin on June 27, 1997.

The objective of the Communication Networks establishment are to raise awareness of schools to water resources,

river & environment, to introduce issues related to environment & water resources management in river basin, to

introduce problem solving strategies, to invite students to have experiences on research implementation &

monitoring in the subjects of chemistry, biology, geographic & social, to increase cooperation among school in

raising awareness to water resources, to improve the teachers’ concept on water resources management &

innovative teaching methods, and to build communication through e-learning activities. Some activities of the

Communication Networks are training for teachers and students (bio-assessment. e-learning, etc), water olympic,

camping, regreening of school environment, river cleaning, campaign on river conservation, competition on

regreening in school environment, competition on water resources conservation, seminar and workshop, etc.

E. Jasa Tirta I Public Corporation

Jasa Tirta I Public Corporation (PJT-I) established in 1990, based on Government Regulation No. 5/1990 (later

replaced by Government Regulation No. 93/1999 to strengthen the organization and permit its jurisdiction to extend

to other basins), is charged with managing the water resources in 40 of the more important benefit producing rivers

(including the Brantas River) of the basin and to operating, maintaining, and managing the major infrastructure in

these rivers. In 2000, the Brantas Corporation was authorized to undertake WRM in 25 rivers of Bengawan Solo River

Basin (an inter-provincial river basin lying in Central Java and East Java Provinces).

The Corporation has no role in irrigation management in the basin except to provide bulk water supply to the

irrigation systems. It provides comprehensive water resource development (mostly non-structural) and utilization

service to fulfill all types of surface water demand, water resources protection, water quality monitoring, flood

operation, O&M of water infrastructure, conservation and providing information, recommendations, public

campaigns and technical guidance.

The business activities of the corporation cover water business and non water business activities. The water business

activities consist of raw water supply for domestic, industrial purposes and hydropower plants. The non water

business activities consist of land rent, tourism in its working area, construction and consulting services, etc. For the

near future, after the new Government Regulation on Jasa Tirta I Public Corporation issued, there are opputunities

for the Corporation to develop new businesses on the development of drinking water supply system and hydro

electric power generation in small scale.

1. Organizational Setup

PJT-I is supervised by a supervisory board composed of central and provincial government representatives and is

managed by a board of directors headed by a president director. Being a national corporation, the authority to

oversee the management and functioning of PJT-I lies with the center through the Ministry of Public Works (MPW),

with the Ministry of State-owned Corporation (MoSC) exercising a fiscal oversight role.

The Minister, who draws his powers from the water law, has supervisory control. The supervisory board has five

members representing the MPW, MoSC, Ministry of Finance (MoF), and local government (with three-year terms)

and undertakes general supervision of the corporation’s program, work plan, and budget. This is the only

institutional setting in which the Provincial Government of East Java (for Brantas basin) and Central Java and East

Java (for Bengawan Solo basin) can directly interact with the work of the corporation and influence the WRM in the

basin, apart from the authority it exercises through other agencies in the basin. To a large extent the central

ministries’ (MPW and MoSC) role overshadows the supervisory board’s functions in the operation of the corporation.

The day-to-day management of the corporation is with an executive board composed of a President Director, a

Director for Technical Planning and Development Affairs, a Director for Financial Affairs, a Director of Operations for

the Brantas River and the Bengawan Solo River, and a Director for Human Resources Development. Four regional

units (division) in the Brantas basin and three regional units in the Bengawan Solo, manage the field water resources

management and special units undertake research, planning, and quality management.

The main functions of PJT-I are (i) water quantity management, (ii) water quality management, (iii) flood control

management, (iv) river environment management, (v) watershed management, (vi) water resources infrastructure

management, and (viii) research and development. In carrying out these activities, the corporation coordinates with

stakeholders such as the State Electricity Corporation, municipal water supply corporations, private and public sector

industries, NGOs, and experts.

The corporation is not responsible for irrigation system management but provides bulk water. In cases where water

supply is made from the irrigation system for non-irrigation functions (water supply to industry), the corporation

coordinates with the concerned irrigation agency. Thus, much of the management decisions are based on a

consultative process through a proactive approach. The corporation is authorized to make most of the technical

policy decisions and some policy decisions related to WRM, such as release of reservoir water for flushing, changes

in water allocation during times of shortage, reservoir operation, awareness campaign.

The corporation, however, has no policy power in areas such as basin planning, basin infrastructure development

and investment, off-stream water quality improvement, tariff fixing etc. In these areas where it is not permitted to

Page 14: 9_TJOEK WALUJO SUBIJANTO_PAPER

14

make policy decisions, PJT-I works through the administrative and consultative channel to influence decisions. As an

organization PJT-I has been very effective in most aspects of the WRM decision-making, coordination, improving

resource base, and working with other basin agencies and stakeholders by adopting a proactive management style

and having a good working relationship with both formal and informal institutions.

2. Continues Improvement and Quality Assurance System

The management of PJT-I are required to have innovations spirits in developing and implementing the new concept

of water resources management. This assignment is a great challenge for PJT-I to be the one of leading water

resources management institution in Indonesia.

Many aspects of IWRM and water governance system were developed and implemented in this basin. River

infrastructures are in better condition, basin productivity and public awareness as well as user’s contributions for

financing O&M activities increase significantly. The key success factor to have supports from stakeholders is

stakeholder satisfaction.

Brantas River Basin is the first river basin in Indonesia who applies Quality Management System of ISO 9001-2000 for

design, operation and maintenance of water resources and infrastructure since 1997 as commitment of PJT-I to

achieve stakeholders’ satisfaction through continuous improvement of the system and responsive actions on

stakeholders’ complaints as reflection of PJT-I’s motto “Identity by Quality”. Besides to anticipate stakeholders and

beneficiaries’ request and to enhance stakeholders’ satisfaction by meeting their requirements, other reasons to

adopt Quality Management System are instrument to meet better water resources management according to the

global standards; effective system is required to improve the company’s performance; efficient, effective and

consistent corporate management; improve employee’s integrity; optimum time and resources usage; improve

employee’s capacity and responsibility; and better communication and improvement in information quality.

After having experience in applying Quality Management System of ISO 9001 for water resources management in the

Brantas River basin, PJT-I has benefits as follows: operational aspect of the company is not affected by change of the

employed workforce (better working methods); improvement in the company’s performance; stakeholders’

complaints are better handled and anticipated; main tasks are undertaken more efficient and effectively;

appreciation from external parties to the company’s existence increases; pilot concept for water resources

management at the basin-wide perspective in Indonesia; better relationship between stakeholders and beneficiaries

and easier to implement Good Corporate Governance (GCG) principles.

3. Corporatization Achievement

As a professional institution, Jasa Tirta I Public Corporation is responsible to develop a proper management system

and technology application for basic and advanced water resources management in the Brantas River Basin. Purpose

of the corporation covers technical aspects, financial aspect, and management aspect.

a. Technical Aspect

For development purposes of water resources infrastructures, flood control, pollution control and other

environmental aspects, comprehensive master plans have been developed in sequence. These master plans were

completed in coordination with related inter-sectoral agencies on mutual agreement.

In implementing the stipulated activities, as designated in the master plan, the responsible corporation carries out

coordination especially with the related agencies. Water allocation – as an example – is carried out through

coordination with the governmental agencies, Jasa Tirta I Public Corporation as managing institution, main

stakeholders, representatives of sectoral users, non-governmental organizations and experts, at the provincial and

basin level.

As result of this coordination, a specific reservoir operation pattern for the Brantas River Basin is prepared by Jasa

Tirta I Public Corporation and agreed by all parties. Implementation of this pattern will be carried out by the

corporation (that is responsible for maintaining the reservoirs), related irrigation agency and other main

stakeholders. This mechanism is used to solve inter-sectoral water allocation and appraise a fair and transparent

result.

For other aspects, like river environment management and water quality management, the same procedure is used.

The governmental agencies, main stakeholders, representatives and experts are consulted and proactively involved

in the implementation process.

In the future plans, the following activities are included into the approach of an integrated water resources

development and management in Brantas River basin:

� Modern data management incorporating an interactive database management and information system. The

planning of the data management should be directed towards development of a Decision Support System,

providing support to short and long term planning and real time decision making. Efforts have to be

CONTINUOES IMPROVEMENT

- Other resources

Page 16: 9_TJOEK WALUJO SUBIJANTO_PAPER

16

undertaken to integrate and update the existing hydrological database of the basin, at provincial and regional

levels.

� Set out and optimize future water demands and allocation establishing a water management system that

entails the allocation supplies, scheduling, operation, and monitoring of the main distribution/collection

facilities.

� Maintain and improve in-stream water quality in rivers, lakes, reservoirs and other water bodies through

development of a water quality monitoring and management system.

� Introducing economic instrument for water pollution control.

� Development of Farmers Owned Company (Badan Usaha Milik Petani – BUMP) to increase irrigation water

efficiency.

� Development of company (as subsidiary of some State Owned Companies including Jasa Tirta I Public

Corporation in Indonesian namely BUMN Hijau Lestari) for watershed conservation and agro industry purposes.

� Development of flood management by planning of necessary measures connected with flood protection in

order to safeguard rural and urban areas.

� Development of a river management system for low water levels and flood flow events in order to ensure

efficiency of the irrigation and water supply mechanism and flood protection.

In the near future, effective Decision Support System (DSS) especially for water quantity management (flood

management and water allocation) and water quality management in Brantas River basin will be urgently required.

This is due to flood and drought magnitude and frequency will increase significantly in the basin due to climate

change impact and will become significant issue in the basins’ water resources management. Water quality in the

basin also become significant issue since the degradation occurs due to human settlements, rapid urbanization

(organic and inorganic load), industrial expansion, excessive sedimentation from land clearance and deforestation.

The application of Decision Support System for water resources management already started in Brantas River Basin

in 1990 by establishing Flood Forecasting Warning System (FFWS) using telemetering system supported by the

Government of Japan. The telemetering system is a centralized data management system consisting of observation

facilities, relay stations for data transfer and supervisory/control/ monitoring stations. In this system, the

meteorological and hydrological data are gathered by automatic and manual operation to the central observation

station in real time. The gathered data are used for flood forecasting and other analysis for runoff and river flow

characteristics of the basin.

The existing FFWS in the Brantas River basin was completely installed and established at the end of at the end of

1990 and started its operation from the beginning of 1991. Although the FFWS in the Brantas River basin is still in

function, the hardware and software set in Jasa Tirta I Public Corporation was the first generation, and this situation

may cause difficulties and problems in operation and maintenance of the system at the moment.

Another existing Decision Support System is part of an integrated river monitoring and water quality control and

management system that was proposed for Brantas River by Indonesian Institute of Science supported by Austrian

Government. The project called ‘Brantas River Water Quality Monitoring and Pollution Management’ was initiated at

the beginning of 1999. The objectives of the project are as follow:

� Establishment of a continuous on-line and an off-line water quality monitoring net work along the Brantas

River and some of its tributaries to monitor, to control and to reduce river pollution.

� Extension of the existing water quantity monitoring network to cover all the strategic points of the Brantas

basin.

� Establishment of a telemetric system for transfer data from monitoring and surveillance systems.

� Development of a Hydrological Information System (HIS) for the Brantas River basin. This includes a central

data bank and data bank tools for the handling of data. The real time data generated from the on-line systems

as well as supplementary data from the river basin need to be stored and made available for management,

research and development activities.

Page 17: 9_TJOEK WALUJO SUBIJANTO_PAPER

17

� Development of a Decision Support System for the modeling of hydrological events and water quality control.

The Decision Support System will use the data from the data base management system or other information

systems to be used in simulation models for conceivably supporting decisions.

A major priority in the project is to obtain real time data for the river basin management. This includes the

installation of an automatic water quality and quantity monitoring network, a telemetry system for data transfer,

establishment of a Hydrological Information System (HIS), central data bank (DB) and a Decision support system

(DSS).

Hydrological Information System (HIS), which is a modern data base management system that incorporates an

interactive database management and information system which is able to cope with a large volume of on-line data

(water quantity and quality) as well as off-line data. It provides a full pallet of tools and functions necessary for

capturing, storing, monitoring and analyzing of aquatic environment related data. The HIS concept is based on client-

server principle with ORACLE as a data base platform using standard tools. Based on the experience on development

of comprehensive data bases and information systems to manage quantitative as well as qualitative data, the

Hydrological Information System (HIS) is extended to cover the needs of the Brantas water quality & pollution

management program. The information system developed is referred to as Brantas Hydrological Information System

(BHIS).

2. Financial Aspect

Jasa Tirta I Public Corporation, step-wisely applies the principle of “full cost recovery”. Beneficiaries like the state

electricity company (in Indonesian: Perusahaan Listrik Negara, abbreviated as PLN), domestic water supply

companies (Perusahaan Daerah Air Minum abbreviated as PDAM) and industries, contribute financially for the water

resources and infrastructure management.

Tariff of the rendered water service fee is decided mutually, based on agreement among the stakeholders. The

service is conducted also on a contract basis that provides security for both parties. In the future, it is expected that

the Basin Water Resources Management Committee will act as consultation forum for having an agreement on the

tariff for each water user.

Jasa Tirta I Public Corporation also generates revenues from non water business activities such as tourism,

equipment rental (steel sheet piles, heavy equipment , etc), construction (dredging in harbour, river, reservoir and

estuary, dewatering and coffering works), engineering and management consulting, water qualitty laboratory

services, drinking water supply and hydro electric power generation in smale scale etc. These non water business

activities can increase the revenue of Jasa Tirta I Public Corporation and optimize the resources which owned and

managed by the Corporation.

3. Management Aspect

As a State-Owned Company, the managing corporate body is subject to various management audit and control.

Management performance of the corporation is judged based on either financial criteria’s as well as good-corporate

performance or best common practice in managing a company. During the last 10 years, the corporation is

positioning itself better, in form of a consolidated water resources management system that is supported by regional

legislation for the operational basis of the management. The corporation also implements a quality assurance system

that ensures good performance of the management body.

Jasa Tirta I Public Corporation was established to solve managerial, personnel and financial problems that loom over

the completed water resources infrastructure in the Brantas River Basin. This task was achieved, not in a perfect

sense, but as a role model for other river basins in Indonesia, this corporate body is an example of what proper

management can do to extend the development benefits to its beneficiaries.

After 18 years management by the corporate body, it was found that the following benefits could be extended to the

beneficiaries.

Page 18: 9_TJOEK WALUJO SUBIJANTO_PAPER

18

Table 4 Management benefits of Jasa Tirta I Public Corporation in the Brantas River Basin

Beneficiaries Unit 1990 2008

Flood control Inundated areas None None

Irrigation Cropping intensity 1.8 / year 2.2 / year

Hydropower Million kWh/year 910 1,182

Raw water for domestic Million m3/year 125 300

Raw water for Industries Million m3/year 115 191

Water quality BOD average 12–16 mg/liter 3–14 mg/liter

Water res. Infrastructures Fair Relatively better

As it could be seen, flood control in the mainstream is maintained with a designated capability to control 50-years

return period flood. Higher than before, hydroelectric power generation in the basin is optimized from 910 kWh

annually to an amount of 1,200 million kWh annually. Agricultural cropping intensity in the basin has increases from

1.8 to 2.2 / year. In matter of water quality, the average water quality in the basin is approaching to designated

standards, eventually it has not yet fully achieved its target.

The benefits from water resources development and management in the Brantas River basin gives very significant

supports to the economic development in the basin, in the region (East Java Province) and National which raise

economic welfare of the area as measured in GDP. Data from Statistics Central Bureau (BPS) shows that Gross

Regional Domestic Product (GRDP) of the Brantas River basin in 2003 amounted to Rp.150,630 billion (approximately

US$17.66 billion), which accounted for 59% of GRDP in East Java (Rp.254,381 billion) and 8% of the national GDP

(Rp.1,786.7 trillion).

II. Improving Water Security

There are many challenges for improving water security in coping with water scarcity, water quality degradation and

water related hazards in the Brantas River basin. Some of the challenges are summarize as follows:

The challenges for improving water security in coping with water scarcity in the Brantas River basin are :

− Shortage of water in a serious drought year. In case of unexpected drought year, shortage of water would

become more serious for meeting the expanded water demand. Water resources is a limited resources

therefore effective and efficient uses of water including water saving has become inevitable for sustainable

society.

− The increase of water demand has sometimes brought about struggle for water because of its limited

resources. The equitable development should be considered and the proper water allocation has become

essential.

The challenges for improving water security in coping with water quality degradation in the Brantas River

basin are :

− Increasing of pollution following by water quality degradation due to the growth of population and economic

development. The main source of pollution are industry, domestic and agricultures.

− Less of environmental awareness by industries, domestic and agricultural people, such as waste water

treatment plant in industries which still not well functions correctly, disposing of waste water and solid waste

directly to the river by the people, and excessive consumption of fertilizer and pesticide by the farmers.

− Ineffective institutional arrangement for water quality management due to less of coordination between

concerned agencies and lack of funding.

− Incomplete regulations and ineffective of law enforcement.

The challenges for improving water security in coping with water related hazards in the Brantas River basin are :

Page 19: 9_TJOEK WALUJO SUBIJANTO_PAPER

19

− The land development for farming and illegal logging in the mountainous area has brought about increase of

flood magnitude in the downstream, land erosion, landslides and thus debris discharge increase. The

watershed conservation would take much time and cost to realize but is essential.

− Flood control works such as the construction of dikes, revetment and other facilities has brought about

accumulation of people and properties in surrounding area of river. This means increase of flood damage

potential. The more safety is required to protect the people and properties from flood.

There are some most important lessons learned to date in coping with water security in the Brantas River basin. Two

lessons learned are described as follows.

The most important lesson learned to date in coping with water quality degradation in the Brantas River basin is the

implementation of the Clean River Program (CRP). To minimize pollution discharge into the river, the CRP which

launched by East Java Government has been implemented since 1989 supported by Jasa Tirta I Public Corporation

and other related agencies. In order to assist in the implementation of CRP, several working team has been set up

such as PROKASIH Working Team, Clean Town Working Team, Industrial Waste Pollution Control Working Team and

Domestic Waste Pollution Control Working Team. The CRP is considered very effective to control water quality in the

river as well as to raise awareness of the stakeholders.

The most important lesson learned to date in coping with water related hazards in the Brantas River basin is the

implementation of the re-forestation and regreening activities by stakeholders including National Movement on

Water Conservation Partnership - GNKPA, National Movement on Land and Forest Rehabilitation - GN RHL, and Eco-

business developed by groups of State Owned Companies including Jasa Tirta I Public Corporation.

To prepare for the future, Jasa Tirta I Public Corporation as RBO in the Brantas River basin in cooperation with

Government and concerned agencies have plans, including investment in infrastructure and non-infrastructures

measures (capacity development).

To increase supply capacity in the future, we have plans on water supply and demand management. On the supply

management, we have plans to continue removing sediment from reservoir to increase storage of the dam (dredging

in Sengguruh, Sutami, Wlingi, Lodoyo and Selorejo Reservoirs), construction of sabo dams in Upper Brantas basin,

optimize reservoir operation with increasing normal High Water Level (HWL) and build emergency spillway,

conducting rain water harvesting and use conjunctive surface/groundwater supply and develop some projects in the

basin. For drinking water supply, Jasa Tirta I Public Corporation as RBO in the Brantas River basin, based on the Draft

of Government Regulation on Jasa Tirta I Public Corporation which expected to be issued this year, will develop

drinking water supply system. The project in small scale have been developed in Tulungagung Regency in 2009.

The Study on Comprehensive Management Plan for the Water Resources Management of the Brantas River Basin -

Master Plan IV (1998) identified three prospective projects in the basin. Those are Beng Dam, Genteng I Dam and

Kedungwarak Dam projects that recommended as the next project after Wonorejo Multipurpose Dam Project. The

capacity of those dams in term of the supply capacity in 6 months drought period are Beng Dam (147 million m3),

Genteng I Dam (70 million m3) and Kedungwarak Dam (54 million m

3).

In demand side, we have plans to continue the implementation of System Rice Intensification (SRI) for water use

efficiency and incentive system, progressive tariff of water service fee, propose changing of cropping calendar, crop

mix, irrigation method and area planted and encourage industries to recycle the water as well. In terms of water

saving, irrigation and industrial water saving should be considered. Proper water allocation should be adopted in due

consideration of changes of land use and industrial structures.

To improve water quality in the Brantas River basin, continuous water quality monitoring system as an important

tool of water quality management will be implemented intensively. Water quality information provided by

monitoring, will support sound decision-making for water quality management at all levels in the basin.

Strengthening of legislation and institution, developing of wastewater treatment system and applying of economic

instrument such as pollution fee based on polluters pay principle, building of community awareness and securing of

maintenance flow also considered as effective measures to improve water quality in the basin.

To cope with flood hazards that happen frequently in the Brantas River basin, some measures consist of both

structural and non structural measures still need to be done in the basin, involving Central Government, Provincial

Government, Regency/Municipality Government, communities, NGOs, etc. The measures that still need to be done

are conducting sediment removal in the reservoirs to secure flood, developing community based early warning

systems, constructing flood control structures (dam, reservoir, flood way, etc), developing river improvement

projects to increase flood capacity of the rivers, watershed conservation by reviewing catchments management plan,

continuing sheet erosion control (terracing, re-greening, re-forestation and construction of sabo works) and

promoting intensive public awareness and initiative in environment issues, establishing advance flood forecasting

and warning system, telemetry system, flood hazard map etc.

Assistances from international parties in forms of capacity-building, transfer of technology and funds to support

monitoring and forecast of weather and climate, as well as advance flood forecasting and warning system in the

basin are needed as measures to adapt climate change impacts on flood in the basins. In addition, systematic

planning and capacity-building are also needed to reduce the risk of disasters and raise the resilience of communities

to increasing floods.

III. Knowledge Networking and Partnerships

Jasa Tirta I Public Corporation would like to develop knowledge networking and partnership with river basin

organization in Spain. In fact, Jasa Tirta I Public Corporation has developed knowledge networking and partnership

with the Ebro Hydrographic Confederation, the Ministry of the Environment, Rural and Marine Affairs of Spain. Jasa

Tirta I Public Corporation and the Ebro Hydrographic Confederation has signed a Memorandum of Understanding on

Cooperation (MoU) in the filed of water resources development and management. The MoU was signed on 12

September 2008 in Zaragoza, Spain by the Presidents of both organizations. Unfortunately there is no progress on

the cooperation done so far.

The area of cooperation under the MoU will include but not limited to institutional strengthening, transfer of

knowledge and technical know how and experience. The indicative areas of cooperation cover river basin

organization and management and irrigation development and management. On river basin organization and

management, some topics already indicated such as institutional strengthening, IWRM programs and tools,

regulation and legal aspects, water allocation, water resources conservation, water service fee and strengthening of

operation and management. On irrigation development and management, some topics already indicated such as

development of pilot project and strengthening of operation and maintenance.

The form of cooperation under the MoU will include but are not limited to exchange of information, research and

technology development, exchange and assignment of experts, organization of meetings, symposium, workshops

and conferences, conducting training programs, study of possible pilot projects on issues of the areas of cooperation,

other forms of cooperation as jointly consented upon by both organizations.

Besides the expectation to realize the cooperation programs, Jasa Tirta I Public Cooperation is interested to develop

Decision Support System (DSS) for water resources management based on the technology developed by the Ebro

Hydrographic Confederation called the Automatic Hydrological Information System (SAIH). Its main objectives are

the optimization of water resources management, flood prevention and flood response to reduce risks and damage

as much as possible and the overall management of the resources.

There is a great interest for optimizing the water resources management of the Brantas River basin in order to have

sustainable benefits from the development and management of water resources in the basin. Jasa Tirta I Public

Corporation as the Brantas River Basin Management Agency has the need for coordination and integration of large

amount of information for decision making process. The information needed covers a wide range of river functions.

The need to meet broad policy objectives such as commitment to sustainable development, to carry out full

economic appraisal for the basin for environmental measures, to consider diverse flood mitigation options, the

requirement for water allocations and reservoir operation, the necessity for water storage and eventually drought

prevention, are a few activities that need decision support and expert advice. Plans and policies for rational use and

Page 21: 9_TJOEK WALUJO SUBIJANTO_PAPER

21

coordinated development require a large amount of background information from various domains. To be useful,

this information must be presented in a readily available format, directly usable by the planner and decision maker.

Proposed questions for discussion during the visit

1. Brief information on water allocation and drought management in the Ebro River Basin.

2. Reservoir management in real time flood forecasting and decision support system (including daily hydrological

forecasts) in the Ebro River Basin.

3. Conservation and protection of water resources in the Ebro River Basin (in urban environment, agriculture

activity, industrial activity and for all the public).

4. Strategy and policy for the development of Public-Private Partnership in operation and maintenance (O&M)

and investment of water resources infrastructures.
