Historical background – Nairobi Supply

• The initial water supply facility for Nairobi was constructed in 1899 abstracting water from Nairobi river in the Athi river catchment.

• Kikuyu springs were first water source developed in 1900-1906. The yield from this source was 5,000m3/day.

• Ruiru (photo) is the second water source developed during 1936 to 1938. Ruiru dam completed in 1950. The yield is 22,000m3/day.

Developed Water Sources for Nairobi City

• Third is Sasumua dam located up stream of the Chania river was completed in 1956. Production is 57,000m3/day.

• Lately, Thika dam and Ngethu t/works system were developed from 1974 to 1994 in three phases. Total capacity is 440,000m3/day.

Development objectives of WaSSIP II

• Rehabilitating selected existing water production, transmission, storage and distribution facilities and waste water collection, treatment and disposal facilities

• Construction of new water treatment works in identified towns

• Expanding piped water supply services to underserved areas and through expansion of primary and secondary distribution systems

• Refining and strengthening the institutional structure, emphasizing on increasing accountability and transparency of the institutional, governance and management framework

Challenges….. (some)

• Huge investment estimated at Kshs 42 Billion required to develop infrastructure to meet medium term (2020) water demands;

• Competing needs for scarce water resources. Athi catchment is said to have 162m3/cap/year against the available 650m3/cap/year Nationally.

• High unaccounted for water.• Environmental degradation and climate change

SITUATION ANALYSIS

• Currently, the water demand stands at 672,994 m3 per day against a production of 501,350 m3 per day – hence a deficit of 171,644 m3/day which is 25% deficit

• It is estimated that current service levels for Nairobi City stand at 76 l/c/d (Source: Draft Working Paper No 1 of February 2011, Agis BCEOM/MIPP)

 Current Status on Sewerage  • The sewerage infrastructure in Nairobi only covers 25% of the area and serves about 40% of the population.

• Currently, there are 178,099 connections to the existing sewerage network.

Completed works

• Rehabilitation of Sasumua dam spillway and embankment to restore the dam’s storage capacity from 5 million m3 to 16 million m3.

23

Challenges

• Currently we still have high ufw standing globally at 36% with some schemes having ufw as high as 85% - Ithanga

• Huge capital investment requirements• Our WSPs are still on a tariff which is not able to

meet operational expenses with very high utility power bills

• Implementation of the new constitution which raises issues about status of Boards and ability to borrow.

24

Way forward

• AWSB has negotiated funding from various agencies to continue with the investment momentum to the tune of USD 160 million (IDA – 145 million and AFD 15 million USD)

• The Board has developed a shopping basket of Kshs 40 billion and is keen to continue implementing targeted projects within its mandate
