We were responsible for the full scope of services, including preliminary design, detailed design and documentation, contract administration and site supervision, for the Leandra wastewater treatment works in Mpumalanga.

A parallel activated sludge BNR plant was designed which incorporated FC dosing for phosphate removal. The project included a new biological reactor, secondary clarifier, drying beds, chlorination contact tank and various ancillary structures.

Flow control to the new activated sludge plant is controlled by a specially designed division chamber.
