The Botswana University of Agriculture and Natural Resources (BUAN) recently took delivery of a solar-powered wastewater recycling system. The installation was supplied by German start-up Boreal Light, which specialises in the manufacture of water treatment systems.
Botswana University of Agriculture and Natural Resources (BUAN) now has better access to water. On 13 June 2023, the public higher education establishment in Gaborone, the capital of Botswana, took delivery of a wastewater recycling system supplied by Boreal Light. The German supplier of water treatment systems commissioned Kenyan start-up Waterkiosk to install the system.
The new water desalination system, the first of its kind to be installed by Boreal Light in Botswana and the Southern African sub-region, has a capacity of 11 m3 per hour, or 264 m3 per day. “The raw water comes from a sewage-fed reservoir that is heavily polluted with a long list of minerals, bacteria, viruses, algae and turbidity,” says Boreal Light.
The water from the Boreal Light system supplies a pivot irrigation system and modern drip irrigation lines at BUAN’s university farm. The aim is to improve yields on the university’s agricultural farm in the face of the growing food challenge.

The Botswana University of Agriculture and Natural Resources aims to support the transformation of Botswana’s agriculture and natural resources sectors by 2027, while also producing competitive, high-calibre graduates. BUAN also aims to play a role in achieving Sustainable Development Goal 2 (SDG 2), which focuses on eliminating hunger, ensuring food security, improving nutrition and promoting sustainable agriculture.
