DAKAR, Senegal – Senegal’s water utility, Société Nationale des Eaux du Sénégal (SONES) has awarded a €7.6 million (4.9 billion West African CFA francs) contract to Veolia to build an iron removal water plant.
Veolia, through subsidiaries OTV and SADE, will design and build a 40,000 m3/day plant, which is part of SONES’s extensive program aimed at substantially increasing the drinking water supply to Dakar and its suburbs.
The investment is part of a plan to improve water quality because of some of the city’s water is sourced from boreholes with high iron content.
Treatment will consist of raw water aeration, physical-chemical treatment and sand filtration. The water will then by disinfected using chlorine produced on site by electrochlorination.
SONES, Senegal’s state-owned urban and suburban water utility, is the contracting authority for this project, which is financed by a West African Development Bank loan.
