1 Water Resources Management Socio-Economic Perspective Tami Shor, Deputy Director (Regulation) Israel Water Authority April, 2010

2 2 Israel is situated at the edge of the desert. Within 200 Km rainfall drops from over 700 mm/year to 150 mm/year. Fluctuations in rainfall are very extreme. Series of drought years are a common Phenomena

Givati and Rosenfeld (2007) related the decrease to decrease in rainfall at the Hermon and Golan Heights MCM MCM Mid Avg

5 Complexity of the water distribution system Different Sources to the main system: ground water, surface water, desalinated water Utilization of the different sources changes based on the hydrologic situation Different types of uses from the main system: domestic, agricalture, industry

10 Actions for Closing the Gap Between Supply and Demand Long Term Water saving and efficient use of water. Water wells purification and aquifers water quality improvement. Increasing capacity of waste water treatment and upgrading effluent quality. Desalination.

17 Actions for Closing the Gap Short Term Drought Actions to Increase the Supply Expanding Desalination Plants Heightened Monitoring of the Water Resources Efficient Use of the Aquifers

18 Drought Wells

19 Actions for Closing the Gap Short Term Water saving and efficient use of water Allowing Reduced Water Quotas for Agriculture Increasing Water Prices - Excess Consumption Levy Rationing Water use for Public Gardening Media publications and Teaching activities Installation of water saving accessories for domestic purposes
