Recovering Resources from Wastewater and Fecal Sludge in Dakar, Senegal

Cambérène, the largest sanitation system in the Greater Dakar area, has focused on three areas through the Cambérène, WWTP: (1) the reuse of wastewater by market gardeners (horticulturalists) around Dakar; (2) energy production from methane gas produced during wastewater treatment; and (3) recovery and sale of treated fecal sludge. This brought economic benefits for ONAS such as additional revenue and for local farmers such as cost savings, as well as environmental and social benefits such as less polution of aquifers.
