The Jordan University of Science and Technology (JUST) has a large campus (11 km2) and has reused water from the university wastewater treatment plant for almost 20 years. Another source of effluent water is located off campus at the Wadi Hassan area, about 4 kilometres south of the university campus. There are two storage lakes on campus: a 132,000 m3 lined pond, and a 110,000 m3-capacity reservoir. These sources of effluent water and the existing infrastructure have encouraged the university to irrigate additional portions of the campus and to support the production of cash crops, field crops and forest trees by reclaimed wastewater. The project had two main goals: 1) to demonstrate that wastewater reuse is feasible for irrigation purposes; and 2) to evaluate the efficacy and economics of growing new types of crops in the northern area of Jordan, utilising the flow from the existing JUST WWTP as well as the Wadi Hassan WWTP.

Results obtained

  • Irrigated areas were extended by 72 hectares to maximise the utilisation of reclaimed water generated by the JUST WWTP and JUST’s allocation from the Wadi Hassan WWTP.
  • Approximately 2,400 trees of various types have been planted to date at the JUST site.

Success factors

Public awareness about water reuse issues and concerns has been raised for all stakeholders — especially students and the local community. In addition, over 45 groups of visitors from off campus were accommodated. Public and private schools, universities, national and international NGOs and agencies visited the projects and toured its reuse sites. Many demonstrations of water reuse in agriculture have been presented to various farmer groups.

Indicators used

The current flow through the plant is approximately 300 m3 per day, and only half of the treatment units are in service. All the plant effluent, after mixing with surface runoff, is used for agricultural irrigation at the demonstration site.

Pilot demonstration farms have been established at Wadi Musa, Aqaba and Irbid, Jordan using reclaimed and treated wastewater for limited and controlled irrigation. USAID has been providing technical guidance and oversight of the project, the MWI through the Water Authority of Jordan (WAJ), and the newly established Water Reuse Unit is providing policy and technical support.
