Stormwater Collection Facilities

Stormwater Collection Facilities

“Mekorot” has two kinds of enterprises around the country for collecting floods – collecting flood water for agricultural use and collecting flood water for domestic consumption:

Enterprises designated for supply of water for domestic consumption – the water is introduced into the ground, is filtered naturally, produced by drillings and provided for urban consumption during months of high demand.

The following plants can be found amongst them:

• The Menashe Rivers Plant – “Mekorot” operates the plant in order to collect the stormwaters of the Menashe Rivers, divert them from their routes and transfer them to the sedimentary basins and the infiltration basins, so they enrich the coastal aquifer. The plant drains the flow of the Taninim, Ada, Barkan rivers and later on the Mishmarot River, to a diversion channel, so they will be inserted in the sands of Caesarea. Thus, “Mekorot” succeeds in taking advantage of the winter floods and transfer them using gravity, without any energy input, to enrich the aquifer. From the aquifer, the water can be pumped regularly, even in dry years.

• The Shikma River Plant – the plant was established for the collection of flood water and their introduction into the southern coastal aquifer. The plant is located near Kibbutz Zikim, about 1.5 km from the Mediterranean coast. Introducing stormwaters into the aquifer enriches the quantity and quality of the groundwater. The infiltration through the layers of soil is similar to a filtration and purification process.

Enterprises designated for irrigation – the floodwaters are collected in reservoirs and combined in the effluent reservoirs designated for agricultural purposes. They contribute to the water sector in Israel from several aspects:

• The ability to fill up the reservoirs during drought years guarantees regular water supply for agriculture
• The stormwaters are blended with the effluent water and reduce the level of salinity
• These waters are usually cheaper, hence the economic viability for agriculture

Amongst these, the following plants can be found: Kfar Baruch, the Ram Pool, the Bsor Reservoirs, the Hazeba Reservoirs, Nikrot, Zukim, Eshet, Ein Tamar and more.
