President of Republic Lays Foundation Stone for Nouakchott Sanitation Project (Pole A)
On 16 December, His Excellency Mr. Mohamed Ould Cheikh El-Ghazouani, the President of the Republic, laid the foundation stone for the Nouakchott Sanitation Project (Pole A).
This project, whose foundation stone laying is part of the commemorative events of the 64th anniversary of National Independence Day, comprises two main components: one for domestic sanitation, and the other for rainwater drainage both due to be completed in 45 months.
This pole includes the moughataas of Tevragh Zeina, Sebkha, and Ksar, as well as parts of the moughataas of El Mina and Teyarett. The rest of Nouakchott will indirectly benefit from the project, through its contribution to the suction and drainage of lake water.
The project, costing 177,609,691 US dollars and financed from the Mauritanian state budget, is carried out by CMEC.
Under the first component for domestic sanitation and water supply, 104,290 linear meters of HDPE CR8 or GRP sewer pipes with diameters ranging from 250 to 1,000 mm will be procured and laid. There are also plans to
– acquire and install 12,300 linear meters of HDPE PN10 or GRP sewer pipes with diameters ranging from 160 to 800 mm.
– acquire and install 66,000 linear meters of 200 mm diameter PVC pipes.
– construct 29 pumping, lift, and discharge stations with flow rates ranging from 16 liters/second to 960 liters/second, and heads from 6 to 17 meters.
– construct an activated bacteria wastewater treatment plant with an average capacity of 19,000 m³/day, expandable to 33,000 m³/day.
The project also includes other installations and works, such as
– manholes and maintenance hatches.
– road crossings.
– the transformation of existing networks: telephone, drinking water, sewage, and electricity.
– dismantling and removing old pipes located along the route of the new network.
The second component of the project, the stormwater drainage system, will involve :
– Supplying and installing 15,747 linear meters of reinforced concrete culverts, with lengths ranging from 300 to 8,700 meters.
– Supplying and installing 1,654 linear meters of HDPE or GRP pipes with a diameter of 1,000 mm.
– Constructing five pumping, lifting, and water discharge stations with variable flow rates ranging from 150 liters/second to 730 liters/second and heights ranging from 7 to 13 meters.
