Treatment and Reclamation Facilities

Examples of Mekorot’s treatment and reclamation plants around the country:

The Shafdan Plant (Dan Region Wastewater)

The plant was built to treat wastewater from towns in the Dan region. It is owned by the Dan Association of Towns for Wastewater and Environmental Quality, an association of seven municipalities, with other towns connected to it. The plant currently serves a population of more than 2 million people. This WTP is considered the largest and most advanced in the Middle East, and treats about 130 million cubic meters of wastewater per annum.
Mekorot is responsible for:

  • Running the WWTP (wastewater treatment plant)
  • Inserting the effluents into groundwater through recharging fields for the purpose of natural filtration and improving the quality
  • Producing reclaimed effluents through the drilling of wells and supplying reclaimed water to the Negev, if the quality that is suitable for unrestricted irrigating of agricultural crops.

 

The Third Line to the Negev

The purpose of this project is to carry the wastewater treated at the Shafdan – as reclaimed wastewater – to the Negev, to irrigate all types of agricultural crops without sanitary concerns for the customer. The plant already began operating on a limited format in 1977, and treated the wastewater of the Southern Dan Region. In November 1989, it went into full operation as a fully integrated system of pipelines (the length of the main pipeline of about 90 km and a diameter of 70 inches), pumping stations and reservoirs, some of which are designed to store the surplus water reclaimed during the winter in order to increase the amount of water supplied for irrigation during the summer months. In the first year of operation, the system conveyed about 80 million cubic meters of recycled water to the Negev. Nowadays, the Third Line carries about 160 million cubic meters of reclaimed water to customers, under an extensive monitoring and control system. The uniqueness of the plant is in the special technology that was developed by Mekorot for inserting the water into the pool inside a natural aquifer, without this being mixed with the existing water. According to demand, Mekorot draws the water through a system of approximately 150 production wells and delivers it to farmers in the Negev, and, simultaneously, it enables the farmers to enjoy the economic benefits. 
By making use of the reclaimed water to the Negev, Mekorot achieves several objectives:

  • Taking full advantage of the Dan Region effluents and preventing the waste of one of Israel's most precious resources - water
  • Improving the water balance in Israel by diverting a large amount of fresh water for domestic and industrial purposes
  • Relocating extensive agricultural processing areas from the crowded center of the country to the Negev
  • Creating green plantations and fertile green fields in areas that were once arid and deserted 
  • Reducing the potential for groundwater contamination and the spread of disease due to the treatment and disposal of wastewater

 

The Kishon Complex

This is the second largest effluent reclamation plant in Israel. The water reaches it after undergoing treatment in the wastewater treatment plants in Haifa and Afula. The facility, which was established in 1984, is designed primarily to supply irrigation water to the agricultural sector in the Jezreel Valley. Before it was established, the National Carrier provided most of the water for irrigation, while the rest of the water was supplied from stormwater that was collected in the Kfar Baruch reservoir. The establishment of the Kishon Complex essentially enabled most of the fresh water of the National Carrier to be diverted to the Haifa area for urban consumption. Today, the plant reclaims about 30 million cubic meters of water for agriculture in the Jezreel Valley and the Haifa area.

 

The Emek Hefer Reclamation Plant

The plant receives the effluent water from the Netanya WWTP and local production wells, and supplies it to towns that are members of the Hefer Valley Water Association, for use in agricultural irrigation. The main function of the plant is the direct supply to consumers during the irrigation season as well as winter storage in three reservoirs: the northern reservoir and the southern reservoir with a total volume of approx. 6.7 million cubic meters, and the Bahan Reservoir with a volume of 0.15 million cubic meters. By using pumping stations located at the reservoirs, the effluents are pumped and supplied directly to customers during the irrigation season. Today, the plant reclaims about 18 million cubic meters for farmers in the Emek Hefer settlements. 

 

The Ashkelon WWTP

Serves all the residents of the city and the industrial zone in Ashkelon, about 130,000 people. The WWTP is jointly owned by Mekorot Development & Enterprise and the Municipality of Ashkelon and it treats wastewater by the activated sludge method. The effluents are produced at the WWTPs on a secondary level and are currently in the planning stages of being upgraded to a tertiary level.

 

The Karmiel WWTP

Collects the wastewater from the towns of Beit Hakerem valley as well as from the industrial zones of Teradion and Karmiel. The quantity of effluents currently treated at the WWTP can cover an area with a population of about 250,000 people. The WWTP is jointly owned by Mekorot and the Water and Sewage Corporation for Karmiel and surrounding area. Close to the WWTP, a tertiary treatment plant, which is owned by Mekorot, is located, where the effluent treatment is competed. The effluent water is supplied to the Damon Reservoir and from there it is supplied for unrestricted irrigation in the area. In the winter season, the WWTP produces surpluses that are transmitted as secondary quality to the Asher Reservoir.

 

The Wastewater Treatment Plants under construction

  • The Nabi Musa WWTP: The purification plant for the wastewater of Eastern Carrier (Nabi Musa) is currently in its final stages of construction.
    The WWTP is intended to provide the average daily flow rate of 20,000 cubic meters;
  • The Nisgav WWTP: is in its initial stages of construction. It is intended to provide the average daily flow rate of 9,000 cubic meters and to produce effluent quality water – for irrigating all crops without restriction.
