The major water resources in the West Bank consist of groundwater and springs, while additional sources include rainwater harvesting.
There are 40 municipal wells in the West Bank that are used either wholly or partially by Palestinians. Their annual yield is around 30 million m3 (EQA, 2002a).
This is insufficient to meet water demand and the deficit is supplied mainly through springs or through Mekorot (the Israeli Water Company). Some agricultural wells are also used for domestic purposes.
