Biwater wins contract to build wastewater treatment facility in Morocco


Biwater, a UK-based water treatment services provider, has secured a turn-key contract from Office National de l’Electricitéet de l’Eau Potable (ONEE) to design and construct a new wastewater treatment facility in Southern Morocco.

To be located in the coastal town of Tarfaya, the new wastewater facility will offer pre-treatment, biological treatment and advanced tertiary treatment, along with ultraviolet disinfection and sludge dewatering.

Biwater will also design the drying beds to reduce the sewage sludge to solids content, which can then be safely transferred from the site for its disposal.

The contract work has already started with earthworks in progress. Biwater has claimed to be working under a fast-track construction programme to reduce the ecological impact of raw sewage along the coast.

After the construction is completed, the company will offer 12 months of operational assistance and maintenance to the local workforce.

Biwater Morocco country manager Yassine Laib said: “This project is part of the country’s efforts to clean the coast of Tarfaya and protect the environment from the effects of wastewater discharged. The project will use treatment processes to meet the people’s need for wastewater treatment in this region.”

Laib continued saying: “After the successful commissioning of similar projects in Tamuda Bay, Khenifra, Aourir and Boukhalef, we are proud to continue our long-standing work to improve sanitation conditions for all across Morocco.

“Biwater, therefore, looks forward to delivering another turn-key solution that will serve the residents of Tarfaya and support the clean-up of its coastline.”

Presently, ONEE and Biwater are constructing Laâyoune’s main wastewater treatment plant, under a separate contract. The facility, which is nearing completion, will include a solar sludge drying greenhouse that can sustainably dry the sludge as a by-product from the wastewater treatment plant.

Earlier this month, the company started development works on the Tamale Water Supply Scheme, a drinking water project in the Northern Region of Ghana.

The $272m contract was offered by Ghana Water Company Limited (GWCL) in 2019 to construct and expand the water supply infrastructure in Tamale.
