Biwater to build wastewater treatment plant in Moroccan city of Tarfaya

The National Office of Electricity and Drinking Water (ONEE) has selected UK company Biwater to design and construct a new wastewater treatment plant in the southern coastal town of Tarfaya.

Biwater has carried similar projects in other Moroccan cities, including Tamuda Bay, Khenifra, Aourir and Boukhalef. The new project “is part of the country’s efforts to clean the coast of Tarfaya and protect the environment from the effects of wastewater discharged”, said Yassine Laib, Biwater’s Country Manager for Morocco.

The new Tarfaya facility will provide pre-treatment, biological treatment and advanced tertiary treatment, including ultraviolet disinfection and sludge dewatering. The drying beds will be designed to reduce the sewage sludge to dry solids content, which will be safely transferred off site for its disposal.

Following construction, Biwater will provide 12 months of operational assistance and maintenance to the local workforce.

Under a separate contract with ONEE, Biwater are currently constructing Laâyoune’s main wastewater treatment plant, which is nearing completion.


This facility will include a solar sludge drying greenhouse that will sustainably dry the effluent sludge produced as a biproduct from the wastewater treatment plant.
