The City of Mafraq, located in northern Jordan near the border with Syria, is served by
the Mafraq Wastewater Treatment Plant (WWTP), which is situated approximately 6 km
north of the city on a 37 hectare (ha) site. Wastewater from the city is conveyed to the
plant through a 6 km 900 mm diameter gravity sewer. The plant, designed for an average
daily flow of 1,850 cubic meters uses a series of 12 waste stabilization ponds to treat the
wastewater generated by the town’s current population of about 55,000 people.
Approximately 24 ha of the site are leased to a local farmer who grows olives, wheat,
sorghum and alfalfa. The treated effluent from the plant is pumped to the fields used by
the farmer and is distributed in ditches for flooded irrigation using a border check system.
