A water corporation. The company develops, operates and maintains the water, sewage and drainage networks of Jerusalem.

The system includes three sewage treatment plants in Jerusalem and its surroundings: the western (the Sorek-Refa’im) Plant that has been operating since 1999, Two more plants – Homat Shmuel and Nebi Musa – will treat the sewage of the eastern basin of Jerusalem. The construction of these two has begun in 2008.  

The Western Sewage Treatment Plant (Sorek) serves the settlements around Jerusalem such as Giv’at Ze’ev and Beithar Iilit.

The Eastern Sewage Treatment Plant (Nebi Mussa) will treat sewage from the north-eastern neighborhoods of Jerusalem (Neve Ya'akov and Pisgat Ze'ev), from Ma’aleh Adumim, Ma'aleh Adumin Industrial Zone and from a few more easterly settlements: AdamAnatot, and Mitzpeh Yericho. The treatment plant is being build in the area of Nabi Mussa in the Occupied Jordan Valley, on a 200 dunam plot will be used for aerated lagoons.  The plant will have the potential to treat sewage from the Og basin and from the Kidron Vally.
The Eastern Plant will replace the Og Reservoir, located near the Dead Sea, which is temporarily being used as a sewage treatment plant. The reservoir will continue to be used as a reservoir for treated effluent used in date Trees irrigation within the settlement farms in the occupied Jordan Valley.
An additional plant is being developed in the Har Homa (Homat Shmuel) settlement neighborhood.
