As part of the Acting project, GRET is supporting the implementation of a sanitation service in the district of Guet Ndar, in Saint Louis du Sénégal, one of the most densely populated districts in West Africa. 25,000 people live here, between the Senegal River and the Ocean. Half of the families living in the district have no sanitation facilities and waste water runs into the river and the sea untreated. Following a feasibility study conducted by GRET in 2012 and technical studies conducted at the start of the project in 2014-2015, priority was given to a collective sanitation value chain. The call for tenders to install the system has just been published by the City of Saint-Louis via the Communal development agency with support from GRET. The operation aims to install 6 km of pipes, while the Senegal national office for sanitation (Onas) is building and renovating two pumping stations. The technical constraints are significant (flush groundwater table, sandy soil, density of habitat…). The work will begin once a contractor has been selected and after the hot season.
