Upgrading the Mafraq Wastewater Treatment Plant in Jordan

2011 - 2015 • USAID


To support the feasibility study and design for upgrading the existing wastewater treatment plant, and fund the construction and construction management to upgrade the plant to a capacity of 6,550 m3 per day


- Construction of a new wastewater treatment plant to replace the old deteriorated plant to produce higher quality of effluent to be used for restricted irrigation.

- Phase 1 operation (partial operation) commenced on March 2014.

- Commissioning and operation of the treatment plant is expected to start on December, 2015.

During construction, it was noticed that the flow received by the plant was lower than expected. In response to this, the existing main sewer line delivering raw sewage from Mafraq City to the plant was inspected and found to be deteriorated and 80 percent clogged. To prevent wastewater from penetrating into the ground and posing an environmental hazard, it was ultimately recommended to replace the sewage line.

USAID approved funding the construction of the sewer line. The negotiated construction cost of the sewer line was $5.6 million, raising the total contract amount to $29 million, of which USAID is providing $23.9 million and the Water Authority of Jordan (WAJ) is providing the remaining $5.1 million. The construction of the sewer line started on January 2015 and is expected to be completed by April 2016.

In order to store treated water for use in irrigation, and to avoid flooding in wadi areas and water wells downstream, WAJ awarded a JD 2.1 million contract for the construction of a reuse system (a 90,000 m3 storage pond, pump station and irrigation pipeline network). The reuse system contract commenced on January 2015 and is scheduled to be completed in October 2015.
