In 2021, Centrient‘s Toansa site partnered with the local community to restore a polluted pond and re-establish its biodiversity. Seepage from the pond was causing damage to the shallow aquifer used for drinking water, raising health concerns. The Toansa team led a project to clean the pond and install a new water treatment system.

One month after the start of the project, the water quality in the pond had already improved drastically, with up to 400,000 litres of sewage water being treated every day. With an area of 2,000 m2 , the restored pond can be used for agriculture and pisciculture and support the rearing of more than 40,000 fish per year.

As well as supporting more than 3,000 community members, the new system for treating the incoming sewage water harnesses renewable wind and solar energy, preventing around 7,200 kg oof potential CO2 emissions annually.
