Challenge

Greater Tel Aviv is Israel’s largest metropolitan area, with a 2015 population of roughly 2.5 million residents (including Tel Aviv, some 20 neighboring cities, and multiple smaller localities). The Dan Region Wastewater Treatment Plant (“Shafdan”) was established near Rishon Lezion in the late 1970s to collect, treat and reclaim municipal wastewater in this large and rapidly growing area. Currently treating 370,000 m3/day of municipal wastewater, Israel’s largest WWTP has undergone numerous expansions and upgrades to meet demand for larger capacity and stricter environmental requirements.

Solution

TAHAL was selected to provide a wide range of services for the Shafdan plant relating to wastewater collection, treatment and reuse. The project included systems for preserving the treated water in defined areas where the water penetrated into the ground. These waters were used subsequently used, as needed, by implementing water supply systems to desert regions, including production wells and the transmission system.

In recent years, Shafdan has been recognized worldwide as a leading example of an advanced WWTP. It is the world’s largest WWTP that treats effluent for use in agricultural irrigation, providing the majority of water utilized by farmers in the arid Negev region in the south of Israel.
