Hagihon

The treated water flows into the Sorek river bed in the area of Kibbutz Tzora, where it is utilized for irrigation.

[8] In 2014, following severe water supply disruptions, residents of the East Jerusalem neighborhoods situated behind the separation barrier, Ras Hamis, Ras Shahada, Dahyat a-Salam and the Shu'afat Refugee Camp, petitioned the Israeli supreme court to force Hagihon to restore full water supply to the area.

In response, Hagigon spokesman claimed that the rapid growth, lack of proper urban planning and rampant use of unauthorized "pirated" pipes in east Jerusalem have overwhelmed the infrastructure.

In a rare collaboration with the Palestinian Authority, Hagihon is leading the Kidron stream restoration project with a budget of close to a billion shekels.

According to the plan the sewage flow to the stream will be stopped and diverted to a new collection line, through an 8-km long pipe to the Og purification facility.

To avoid damage to the natural valley as well as to the Mar Saba Monastery and nearby archeological sites, the route of the sewage line was diverted from the stream itself, through a 60 meter deep, 1.3 km long tunnel.
