Many water utilities in Pacific Island Countries (PICs) have problems meeting the continuously increasing demand for water in part because more water is lost through leakage and wastage than is actually delivered. With more pressure on limited and vulnerable water resources influenced by an increasingly variable climate regime, many PICs have realised that the key towards sustainability lies not in costly infrastructure extension but in sound management of existing water supplies.

Investing in cheap, practical and simple demand management techniques is a known solution for addressing water scarcity challenges. But how could cost-efficient solutions be identified, in contexts where geography makes important differences, where water demand data are not consolidated and where economic reasoning is still unfamiliar to most decision-makers? How could economic analysis support the design of national priorities that would meet water demand management challenges? And how could Mediterranean countries share their experience in implementing such solutions?

In any water supply network, a major maintenance expenses go for repairing leaks and breaks of old pipelines. Moreover, during the repaire of breaks, the water service will be interrupted and the customers will not be satisfied.

Since the year 2002-2003, KAHRAMAA (or Qatar General Electricity and Water Corporation) started implementing water demand management in gradual stages by optimizing water pressure in the upstream and downstream parts of the water network which decreased the rate of leaks and breaks.  In addition an advanced pump operating technique to minimize the rate of breaks and leaks in the network was introduced.

Implement water demand management by optimizing the upstream and downstream of the network and also following an advanced pump operating technique which will minimize the rate of breaks and leaks in the network.
