A multi-stage water treatment plant project undertaken by WEC Water, a leading South African engineering, procurement and construction (EPC) company, specialising in water and wastewater treatment, has been completed and commissioned at Kasane in the northern region of Botswana. The new treatment plant provides secure and safe drinking water to the local communities.

The water treatment plant produces 16 MLD of potable water for a local population of 90 000 people, as well as for businesses in the region. It replaces an older facility that was no longer capable of treating water to meet the increased demand of a local economy undergoing rapid growth.
WEC was appointed as the mechanical and electrical sub-contractor and was responsible for the design, manufacturing, delivery, installation and commissioning of the water treatment works.
Raw water is drawn from the Chobe River and is treated by clarification, followed by gravity sand and activated carbon filtration and final disinfection by dosing chlorine dioxide. Ruan Kellerman, Senior Project Manager at WEC Water says, “The recent economic growth of Kasane, particularly in the tourism sector and associated businesses, has spurred the Botswana Government to upgrade its municipal services in the area. This upgrade aims to accommodate not only the influx of tourists and tourism facilities, but also the resultant increase in the number of associated businesses and workers that are flocking to the area.”
The primary objective of the project was to guarantee that the treated water, sourced from the Chobe River, adhered to the BOS 32:2015 drinking water standards. The plant is designed to supply potable water to one of the nation’s fastest growing regions and to accommodate future scalability.
