| Project Information: |
Treated effluents from the Haifa Treatment Plant are delivered under the scheme via a regulating reservoir at Yagur to the Upper Kishon Reservoir where, after a detention period of two months, the effluents are delivered to the existing Kefar Barukh Reservoir. Mixed with water from the other three sources, the water is then supplied either directly or via the local Ta'anakh, Gilboa, Ramon and Tabor operational reservoirs. These effluents will in the ultimate development stage provide 45 percent of the water supplied to the area.
Principal project components:
• Effluent pumping station consisting of low head pumps delivering the effluents from the treatment plant to the Yagur regulating reservoir, and high head pumps delivering the effluents to the upper Kishon Reservoir.
• Chlorination plant at the pumping station treating all water pumped to the Upper Kishon Reservoir
• A 36-inch dia, 30-km long, conveyance main from the Haifa City Treatment Plant to the Upper Kishon Reservoir
• Supplementary chlorination plant at the Reservoir
• Upper Kishon Reservoir with a capacity of 12 MCM
• Kfar Barukh reservoir impounding storm runoff and water from the National Water Carrier with a capacity of 8 MCM
• Intake tower in the Kfar Barukh Reservoir delivering water to the adjacent pumping station for supply of water to the Jezreel Valley Irrigation Supply System.
The tower is designed to enable water to be pumped from various reservoir levels in accordance with water quality requirements.
The system supplies water of a quality suitable to most crops grown in the valley. Monitoring of water quality delivered to the system shows that the process eliminates bacteria and viruses and that the dissolved oxygen content throughout the detention period ensures that no noxious odours emanate from the reservoir. The system also provides for diversion of all saline wastes from the industrial plant wastes prior to delivery of the wastewater of Haifa City to the Treatment Plant, as well as diversion of saline spring flows and saline storm runoff.
Total annual supply: 20 MCM. Total construction cost: US$ 110 million. |
