The reservoir located near the Dead Sea receives the sewage from the north-eastern neighborhoods of Jerusalem, from Ma’aleh Adumim and from a few more easterly settlements: Adam, Anatot, and Mitzpeh Yericho.
It is temporarily being used as a sewage treatment plant, until the completion of the Eastern Treatment Plant’s construction.
The sewage is conducted to the reservoir in a 23 km long pipeline, 14-24 inches in diameter.
The sewage that flows to the Og Reservoir, undergoes, en route, primary treatment and screening to prevent blockages and disruption to the continuous flow. The reservoir takes in 20,000 cubic meters of sewage per day, and installed in it are aerating systems that enhance the quality of the treated effluent. Then the treated sewage is used for irrigating date-trees in the Dead Sea area and the Jordan Valley.
