Jerusalem Water Undertaking Energy prices and the effect on water sector
Water Resources • Water Purchased • Water produced
Water Purchased • JWU daily water needs is 50000 m3/ day • Available quantity is 42000 m3/day • Population served is 330000 • Number of customers is 550000 • Deficit in water supply is 8000 m3/day • Water availability from our own resources is 8000 m3/day • Water purchased is 34000 m3/day
Water Purchased • Water purchased from 6 connections • Bitunia connection is the biggest (32000 m3/day) • Water price before pumping is 2.6 NIS/m3 • Tow connections Hizma and Shu’afat , water price is 4.15 NIS/m3 (Jehoon)
Water production • Ein Samia well field is a sub-basin of the Eastern Basin • Five wells were drilled in Ein Samia • The area has a ground elevation of 415 masl • Total discharge 8000 -9000 m3/day
Well # 1 • Drilled in 1962 • Shallow well • Recharged by yearly rainfall • Heavy rain recharge the perch aquifer within 3 days • Depth 60meter bgl • Diameter is 2.5 meter • Pump setting 52 meter bgl • Two submersible pumps are working in the well • Pump discharge is • 170 m3/hour • 120 m3/hr
Well 2/a • Drilled in 1964 and developed in 1994 • Upper aquifer • Depth 251 mbgl • Pump setting 225 mbgl • Diameter 14 “ • Discharge 125 m3/hr • Operating hours 14 hr/day
Well # 3 • Drilled in 1982 and developed in 1996 • Lower aquifer • Depth 529 mbgl • Pump setting 357 mbgl • Diameter 16 “ • Discharge 173 m3/hr • Operating hours 22 hr/day
Well # 4 • Drilled in 1990 and operated in 1994 • Lower aquifer • Depth 616 mbgl • Pump setting 471 mbgl • Diameter 16 “ • Discharge 60 m3/hr • Operating hours 10 hr/day • Not working in these days
Well # 6 • Drilled in 1999 • Lower aquifer • Depth 580 mbgl • Pump setting 350 mbgl • Diameter 17 5/8 “ • Discharge 220 m3/hr • Operating hours 18 hr/day
The difficulties in Meeting the Water demand • JWU has a water deficit right now of 20% • Each year the population increases by 3 % • Internal emigration reaches 18% of the served population (Concentrated in Ramallah) • Ministries and governmental institutions concentrated in Ramallah • This increase the water demand by 10 %
The difficulties in Meeting the Water demand • EinSamia production is very limited to Max. quantity of 10000 m3/day • Purchased water is fixed • Any additional purchased water depend on PWA negotiation with the Israelis • There is no yearly automatic additional water • JWU had applied for drilling more wells in Hizma area since 2002 • The verbal approval submitted to JWU before two years • The location of the borehole changed five times till now
