COMMISSIONING OF THE WASTEWATER TREATMENT PLANT (STEP) IN TANGER AUTOMOTIVE CITY ACTIVITY ZONE

Signed in 2018, the Tripartite agreement had brought together the two developers, Tanger Automotive City and Al Omrane, for the realization of off-site infrastructure works for liquid sanitation of the new city of Chrafate and the TAC industrial zone with the technical assistance of ONEE.

The works consisted in the implementation of a transfer of raw water by pumping to a new wastewater treatment plant with a total population equivalent capacity of 53,400, built according to the low load-activated sludge process, a work with a cost about 210 Million Dirhams MAD.

Downstream of the tertiary treatment, pumping station has been designed to discharge to an elevated reservoir with a capacity of 500 m3. This tank plays both the role of storage for watering and allows the loading with gravity discharge of the excess of treated water to the Jnan Mokhtar wadi.

All wastewater is now treated and transferred to the plant with excellent treatment performance, in line with the regulations. The treated water is under no circumstances discharged into the water sources surrounding TAC and is intended for the watering of green spaces in the TAC areas and the city of Chrafate and are subject to other secondary uses (washing…).
