60 m deep tunnel and a joint wastewater treatment facility: This is how the Kidron River will be restored

In the Press

The estuary of Jerusalem and the PA, which for years flowed to the stream, caused a severe
environmental hazard in the Judean Desert. Yesterday the cornerstone was laid for the
restoration project – and the purified water will be used to irrigate Israeli and Palestinian date
plantations. 1.3 km long tunnel will prevent damage to nature. Jerusalem Mayor: “Green
enterprise of national size”

Cornerstone for Kidron Joint Israel-Palestinian Wastewater Treatment Facility
For years, the sewage from Jerusalem and the Palestinian Authority has flowed to Nahal Kidron,
causing severe environmental damage in the Judean Desert. The wastewater seeped into the
groundwater and the banks of the stream were filled with construction waste and garbage.
Yesterday, the cornerstone was set for the Kidron River rehabilitation project and the

wastewater transfer to a treatment plant – with the purified water used to irrigate Israeli and
Palestinian date plantations.
It is a program of more than NIS 800 million, which includes rehabilitation and replacement of
damaged sewage infrastructure, laying of infrastructure for new wastewater disposal, building
waste and refuse removal, wastewater absorption in the “Og” treatment plant and making it
usable for agriculture.
The Kidron River route starts from Mount Scopus in Jerusalem and descends into the Judean
Desert through the Hurkanya Valley to the Dead Sea area. The wastewater comes from
downtown neighborhoods, including Safra Square, where the capital city and eastern
neighborhoods are located.
As part of the project, the sewage will be stopped and a collection line will be drained to drain
the sewage for several kilometers. The Palestinian Authority will also drain its sewage through
an eight-kilometer pipe. These wastewater flows will also reach the Joint Wastewater
Treatment Facility in Og River Valley.
One of the complex parts of the plan is the construction of a tunnel that will lead the
wastewater into the area of the Kidron desert, in order to avoid damaging nature and the
ancient monastery of Mar Saba. It should be noted that the area in this section is not very
accessible and the stream channel passes over archaeological sites and heritage sites. To avoid
damaging them, a route will be diverted from the sewage collection from the river channel and
an infrastructure tunnel will be developed at a depth of about 60 meters, about six meters wide
over 1.3 kilometers.
Inside the tunnel, wastewater collection systems will be located along the Judean Desert and
will be temporarily absorbed in the wastewater treatment plant in the Hurkania Valley where
sedimentation and treatment ponds were used.
Jerusalem Mayor Moshe Leon said: “For the first time, we are implementing a green project of
national size. The project reflects our commitment to the environment and its conservation as
green and clean. This is just one aspect of Jerusalem’s revolution in environmental matters,
improving its face and making it a greener city.”
Minister of Water Resources MK Ze’ev Elkin added: “About half of Jerusalem’s sewage is
polluting the Kidron River – which is one of the most serious environmental hazards untreated
so far. A lot of hard work was done here, which included a lot of coordination with government,
military, municipal and the Palestinian Authority. ”
Elkin went on to say that “despite the many difficulties, we did not give up and our vision
becomes a reality. Not only will Jerusalem’s sewage no longer pollute the environment, but it
will serve as irrigation water for Jordan Valley farmers and Palestinian farmers.”

Avi Blashnikov, chairman of the Gihon Municipal Water Utility and the sewage treatment plants
in Jerusalem, concluded: “We are embarking on one of the important projects for the State of
Israel, the city of Jerusalem and the residents of the surrounding area. This is a project that will
fully address the wastewater problem of the eastern city and all the communities along the
Kidron and restore the river’s majesty, environmental, heritage, tourism and historical
splendor. ”
