Estimation of Non-revenue Water in the Water Distribution Network of Sourif Town

Abstract

The water supply utilities should fulfill the water requirement with quantitatively and qualitatively. Drinking water systems exposed to manmade hazards that are common in Palestine. Among manmade risks is the water loss, which remains a major concern in Palestine. Levels of water losses estimated to be approximately 45 to 50 percent, high by international standards.

High levels of water losses reflect huge volumes of water being lost through leaks, not being invoiced to customers, or both. It seriously affects the financial viability of water utilities through lost revenues and increased operational costs. The waste of resources resulting from high water loss levels in developing countries like Palestine is considerable.

SourifTown is one of the Palestinian towns which has a big problem in its water distribution through a high level of water loss. the water distribution system in the town is old and it is suffering from bad operating and management conditions. The water losses in these water network is at increasing trend. This is expected to make the management of these water network at risk or being failed and instead of being a financial resource for municipalities. Thisstudy is concern with estimating and analyzing the non-revenue water in the water distribution network at SourifTown. The result of this study shown that the non-revenue water in Sourif water distribution system reaches 38.46% in year 2016 with 140000$ this is because the water distribution system is old and weak.
