Al Wahda Dam, Morocco

Protecting an area prone to frequent flooding, irrigating agricultural fields, and generating electricity. These are three equally important objectives achieved in Morocco, in the M'Jara region, through the construction of the Al Wahda Dam in the province of Sidi-Kacem.

Commissioned by the Hydraulics Administration of the Ministry of Public Works (AH) in collaboration with the National Office of Electricity (ONE), the facility is located on the Ouergha River. It consists of an 88 m high earth-filled dam, creating a reservoir of 3.8 billion cubic meters of water, and a power station at the base of the dam with a total installed capacity of 247.5 MW.At the time, the installed capacity of the power station alone represented 22% of all installed capacity in Morocco.

Among the project's achievements are the protection of the Gharb plain against periodic devastating floods, irrigation of over 100,000 hectares in the Gharb plain and the lower Ouergha valley, production of 400 million kWh of electricity per year, and the transfer of over 600 million cubic meters of water to the southern regions of the country to address the characteristic water deficit in these areas.

The Al Wahda Dam site is approximately 35 km as the crow flies from the city of Ouezzane, 5 km from the village of M’Jara, accessible from the provincial road RP No. 26 connecting the cities of Ouezzane and Fes.
