Maun in Botswana to get drinking water plant from Veolia

Feb. 5, 2013 - PRLog -- The new plant will augment the supply from existing underground water sources which become impractical to maintain during the nearby Okavango Delta’s flood season. To maintain consumer demand during these periods, the plant will source water directly from the river.

“River water is high in dissolved organic compounds that give it its characteristic brownish colour and earthy smell and taste, despite its normally low turbidity,” says Peter Healy, Managing Director at VWS Envig Botswana. “To make this water suitable for human consumption, we opted for clarification by means of ballasted flocculation to remove the extremely light-weight organic particles that would otherwise settle very slowly.”

Veolia will install its patented Actiflo™ high-rate water clarification system. Featuring footprints that are five times smaller than conventional clarifiers, the Actiflo™ will achieve rapid settling with the help of Actisand™ – a ballast designed to rapidly flocculate and settle organic particles.

“After clarification, the water will be polished with multimedia and granular activated carbon filters, and finally disinfected before being fed into the town’s pipeline system,” says Healy.

Veolia is also responsible for a booster pump and delivery pipelines. “This involves replacing the main distribution pump and connecting the new station with minimal disturbance to the current water supply,” concludes Healy.
