Abstract

Israel is experiencing shortage of water due to growing demands, especially in the urban sector. Two complementary approaches are available to cope with this situation: the conventional way is to augment supplies; the other, which was studied in this research, is to reduce demands, so they are in better harmony with the existing supply.

The research had two main objectives: to estimate the existing and potential saving in water use by the Israeli urban sector, and to formulate operational recommendations for enhancing water savings.

The core component of the research is a comprehensive feasibility study for achieving water savings in households, which covered technical, legal, social, administrative and economic aspects.

The main findings are that water saving should be a preferred means for closing the gap between demand and supply, and that it is economically worthwhile to save water. While the theoretical water savings in the urban sector can be as high as 40%, the current saving by Israel's households are 15%-20% of the consumption that would occur without any saving. The findings show that a further saving of 10% can be achieved. A main conclusion is that it is important and feasible to establish the reliability of water savings, so it is an integral component in planning the future water sector. This can be achieved by strengthening continuous water saving education and public campaigns, promoting the development and use of water saving devices, and removing legal barriers to certain conservation action.
