Water - Management and Technology

Projects and Partners in Water

KKL-JNF has partners and friends worldwide who share its vision of advancing harmony between people and their environment in Israel and around the world. As Israel's largest green organization, it initiates projects that have both local and global impact. KKL-JNF offices in countries throughout the world serve as a bridge that creates a global network for protecting the environment and promoting projects in the fields of ecology, water, research and development, forestry, international cooperation, and more. Visitors to Israel from abroad often make a point of visiting projects funded by international friends of KKL-JNF, seeing for themselves how the world is in fact a global community.

We present just a few examples of KKL-JNF projects in the field of water management, undertaken with the support of its friends and partners worldwide.


Water for Life

Ma'ayan Tsvi Reservoir


The northern coastal plain KKL-JNF reservoir, Ma'ayan Tsvi, collects two million cubic meters of winter floodwater, used for crop irrigation during the dry months. Israel leads the world in the use of recycled water, where more than 70 percent goes to irrigation.

Idan Reservoir


The Idan Reservoir, built by KKL-JNF, is 1 million cubic meters in volume and harvests winter flash floods, providing water for agriculture in the southern region desert during the dry months.

Sderot Reservoir

United States, Canada

Located in the western Negev desert region, the 1 million cubic meter capacity, KKL-JNF reservoir receives treated industrial and domestic wastewater, which is then used to irrigate field crops and orchards in nearby communities.

Nahal Harod


Nahal Harod is one of the most beautiful streams in the Lower Galilee, flowing some 35 km westward through the Jezreel Valley to the Jordan River. KKL-JNF has helped rehabilitate the stream and continues to create accessible leisure and recreation projects along its banks.

Sharona Reservoir

Switzerland, Germany

The 3 million cubic meter recycled water reservoir in the Lower Galilee, helps solve both the area's growing sewage problem and the dearth of clean water. It receives treated wastewater from the region's communities which is then used to irrigate crops, saving an equivalent amount of precious fresh water.

Shamir Drills

United States

The Shamir Drills are another KKL-JNF project in advanced water technology in the effort to save precious fresh water. The drills, each 1.3 km deep, extract some 25 million cubic meters of water annually from a yet untapped fossilized aquifer.

Biofilter – Kfar Sava

Canada, Australia

This innovative pilot project impounds rainwater and purifies it using biological methods in a simple and cost effective way. The purified water is used to irrigate urban parks and gardens and to enrich the groundwater.
