The Dan Region Association of Towns for Sewage and Environmental Issues (“Igudan”) was founded in 1956 by seven major towns in the Dan Metropolitan Region, including the City of Tel Aviv. According to its articles of incorporation, Igudan is responsible for the collection, handling and treatment of sewage in the Dan Region.
The Association established a subsidiary company (Dan Region Water) in the mid 1980s which constructed the Dan Region Wastewater Treatment Plant (“the Shafdan”) near the city of Rishon Lezion. Although Dan Region Water is a subsidiary company of Igudan, it acts as a separate and independent business unit. Dan Region Water operates and maintains the Shafdan Plant and is continually promoting new projects for the purpose of its upgrade and development.
Igudan operates 70 km of pipelines and a number of pumping stations, through which sewage from its original 7 member municipalities and another 19 municipalities around the Dan Region is collected and conveyed for treatment at the Shafdan Plant. After the treatment process at the Shafdan Plant, the purified effluent is collected by the Israeli National Water Company (“Mekorot”) and used as a primary source of irrigation for agricultural activity in the Negev Desert. The Shafdan Plant is the largest wastewater treatment plant in the world that treats effluent for use in farm irrigation.
Altogether, Igudan serves a population of about 2 million people and treats approximately 370,000 m3/day of municipal wastewater at the Shafdan Plant.
