Israel’s Water Situation:

Data, Challenges, Responses

Similar challenges face other countries in our region and

in several other regions, but the responses have to be

adjusted to local conditions and capabilities

Uncertainties and Outcomes

Sources of uncertainty: population (size and distribution), demands (urban, agriculture, nature, regional), hydrology (precipitation and recharge), performance of system components, costs and benefits, pricing, laws and regulations, politics, international conditions

Desired outcomes: reliable supply of water quantity and quality, serve people, agriculture, protect species, efficiency, income, net benefit

Negative outcomes: loss of service, shortages, loss of species, financial loss, loss of professional reputation, loss of political position

Page 10: Israel’s Water Master Plan

The Stephen and Nancy Grand Water Research Institute Technion – Israel Institute of Technology

Coping with Uncertainties

We recognize, we admit, and we allow that decisions (political/public as well as private) are taken with a subjective attitude (bias). This is partciularly true for decisions under uncertainty, which are difficult to grasp and to communicate, decisions whose consequences and uncertain.

And still, we strive to provide the DMs and society with tools that expose the meanings of uncertainty and the consequences of making decisions under uncertainty, so decisions can be made “with open eyes”, and have a good chance of resulting in minimum future regret (a possible definition of sustainability).

Page 11: Israel’s Water Master Plan

The Stephen and Nancy Grand Water Research Institute Technion – Israel Institute of Technology

Challenges Pressures

Large hydrological variability and

uncertainty with respect to future

hydrology

Possible impact of climate change

Frequent change in Israeli politics and

replacement of Ministers

Uncertainty in the political and

management domain can be the

most difficult to deal with

Page 12: Israel’s Water Master Plan

The Stephen and Nancy Grand Water Research Institute Technion – Israel Institute of Technology

Challenges Pressures

In the past >70% of fresh water were

used by the (politically powerful)

agricultural sector

As long as water for agriculture was

subsidized the Ministry of Treasury

refused to allow desalination

Population growth urban demand

for more potable water, now >50%

Result: overuse of the sources

Page 13: Israel’s Water Master Plan

The Stephen and Nancy Grand Water Research Institute Technion – Israel Institute of Technology

Challenges Pressures

Declining water quality in the sources

caused by human activities and

lower water levels

Rising quality standards for water (we do

have very good quality at the tap)

and for treated wastewater

Water agreements with our neighbors

potential reduction (?) of our share of

the regional resources

Page 14: Israel’s Water Master Plan

The Stephen and Nancy Grand Water Research Institute Technion – Israel Institute of Technology

Challenges Responses

Reduced by more than 60%(!) fresh

water supply for irrigation

Replaced by sewage effluents, and

water productivity has multiplied

Water pricing moving towards full cost for

all sectors (including agriculture)

Water conservation in the urban sector

through pricing, regulations,

campaigns, education

Challenges Responses

Desalination of seawater (now ~300

mcm/yr in three large plants):

550-600 mcm/year by 2013

750 mcm/year by 2020 – decided,

subject to continuous re-evaluation so

as not to over-develop

Desalination of saline groundwater:

50 mcm/year

Sewage reclamation and reuse:

Expand: 300 500 mcm/year

Page 28: Israel’s Water Master Plan

The Stephen and Nancy Grand Water Research Institute Technion – Israel Institute of Technology

Israel’s main failures

Overuse of the natural sources

Quality deterioration of the sources

Delayed decisions on large scale

desalination

Late attention to urban water

conservation

Governance of national infrastructures:

lack of coordination, slow statutory

and budget processes

Page 29: Israel’s Water Master Plan

The Stephen and Nancy Grand Water Research Institute Technion – Israel Institute of Technology

Israel’s main accomplishments

Integrated national water policy and

central control, towards regulation

Highly integrated water supply system

Efficient water use in agriculture

Urban demand management

Reuse of sewage effluents

Large scale sea-water desalination +

desalination of brackish GW

New Water Master Plan

~20 domains of policy, e.g., water and agriculture,

water for nature, protecting natural sources,

pricing, regulation

~ 5-25 components in each

Several alternatives policies for each component,

spanning a wide yet possible range

A set of criteria and indices for evaluation

Evaluation, synthesis, recommendations

Consequences: budget, major actions, constraints,

In 2008, an additional 46 mcm of floodwater was used that was not taken into account. (1) Total average replenishment of natural freshwater, less losses for water with less than 400 mg. of chloride per liter. (2) “Desalination of sea water” – according to the approved government decisions. (3) “Required supplement” = the difference between total consumption of freshwater (bottom table) and total sources of freshwater.

(1) Regional consumption includes supply to the PA and Jordan. (2) Some of the treated wastewater used for nature and landscape is treated wastewater that is not actually used, and flows in ri verbeds. (3) The decline in consumption of freshwater for agriculture is contingent on conversion to high quality treated wastewater, and a change in definitions of well protection radii.

Israel can meet the water needs of the increasing

population to 2050 and beyond, at a reasonable cost

[which I have not discussed explicitly].

Many places in the world are facing mounting water

challenges, so Israel’s experience is relevant as an

indication of what does and will happen, what can and

should be done and what should be avoided, and what

some of the responses and solutions might be.

These solutions have to be adapted and adjusted in each

country to the local physical, social, economic and

political conditions.
