The Center of Transboundary Water Management (CTWM) is looking at methods to reduce wastewater pollution while increasing water supply to households and communities in the West Bank located outside of the region’s wastewater treatment network. Through the construction of greywater recycling systems and the development of a multi-player regional wastewater treatment network, CTWM seeks to find a decentralized solution to this important issue.
Appropriate wastewater management in the off-grid rural sector of Israel and the West Bank is essential. These communities lack the necessary infrastructure to safely treat their wastewater and more importantly to reuse treated wastewater for irrigation in a region fraught with water scarcity. This research seeks to make the case for a decentralized approach to wastewater management and reuse for communities not connected to an energy grid and with poor or non-existent sewerage infrastructure.
The research aims to promote environmental protection of freshwater sources through the promotion of decentralized, low-cost and socially acceptable sanitation treatment of household black (sewage) and gray (washing, showering) water. Furthermore food security is enhanced by providing a secondary source of water for farming through the reuse of the treated greywater for agricultural irrigation. The holistic project approach addresses two elements; (1) technical/infrastructure, and (2) social/communal elements. The research aims to create a sustainable, replicable framework for cross border collaboration intended to expand the entire water cycle; from water resources to wastewater treatment needs in the community. Addressing this water and wastewater problem in a transboundary approach will encourage peace building through cross-boundary cooperation and mapping of waterscapes. Waterscapes are defined as the political, economic, cultural and ideological dimensions of the community’s relationship to water and its productive capacity.
Kibbutz Ketura (Funded by Osprey) One of the first greywater recycling and treatment was built on Kibbutz Ketura, a kibbutz located in the Arava desert in Israel and home of the Arava Institute for Environmental Studies (Arava Institute). This systems is connected to some of the Arava Institute student dorms and is treating greywater for 16 students year round. This system, funded by Osprey, is connected to a family drip irrigation kit donated by Israel company, Netafim. Each semester, students from the Arava Institute have the opportunity to carry out independent research projects on the system – everything from water quality monitoring, cultural perceptions on greywater reuse, and plant productivity using reclaimed greywater.
Sachnin, Arab town, Israel (funded by USAID) In Sachnin, an Arab town in the north of Israel, USAID has funded the construction of a greywater system at the Towns Association for Environmental Quality (TAEQ). TAEQ is an environmental community center and environmental organization serving the six Arab towns in the Bet Natufa valley of the Galilee. With more than 1,000 visitors a year, this system plays a role in TAEQs work to promote sustainable development and community action.
Halhul, West Bank (Funded by USAID) A USAID funded greywater system was built in the Palestinian town of Halhul, located north of Hebron. This system was built in the household of seven, and provides the family with 10 cubic meters of water per month, which reduces their need for water from the public network by 30-60%, depending on the time of year. The mother in the family shared with an Arava Institute student that “water is the life for humans, for plants, for all. We pray for water and rain to come. This water is beneficial and we use the water in many purposes.”
Deir Hatab, West Bank (funded by USAID) Deir Hatab is a Palestinian town to the north east of Nablus. This system serves a family of 8, with one more baby on the way this Spring. The family is using the grey water to irrigate citrus trees and olive trees in their home. Zawata, West Bank (funded by USAID) The last system funded by USAID was constructed in Zawata, a Palestinian town located to the west of Nablus. This family of six uses the water produced by their greywater system to water lemon, apple, fig, and almond trees in their home.
Deir Salah, West Bank (funded by USAID) A USAID-funded greywater system was constructed in the Palestinian town of Deir Salah, located to the east of Bethlehem. This system is run through the home of a family of seven. The father of this family is dependent on olive tree wood for his business, as he creates beautiful sculptures sold in local tourism businesses. In addition to providing irrigation for the trees, the family takes advantage of the new market this system as opened for them. As the mother shared with the Arava Institute that “the project is very helpful. We use it for producing crops that we sell in the farmers market.”
Zawata, West Bank (funded by USAID) A greywater system, funded by USAID, was constructed at the home of a family of six in Zawata. Zawata is a rural Palestinian town in the West Bank located just north of Nabulus. Historically, Zawata was known for its production of winter crops and citrus fruits irrigated by the fresh waters of local springs. This reality no longer exists and the community depends on unreliable water and wastewater networks. The family in Zawata is now able to irrigate their land using water from their greywater system, both supplying food for the family and hopefully soon in the local market.
