The Botleng Wastewater Plant is situated in the township of Botleng, just outside the town of Delmas.  The plant is owned by the Victor Khanye Municipality and was designed by Moedi Consulting Engineers with Headstream Wastewater Treatment and Bluewater Bio providing the HYBACS® process design.Phase 1 of the Plant has been completed as a 3.5ml/d HYBACS® plant containing 2 SMART units.

  • Type: Municipal Sewage Water
  • Plant Capacity: 3,500m3 per day
  • Installed April 2011
  • Operator: Victor Khanye Municipality
  • Average electricity = 75kw/h = 40% saving from conventional AS
The Botleng plant was successfully commissioned in June 2011 and after a 5-month period of being operated by the municipality’s consulting engineer it was handed over to the municipality in December 2011.  During the period prior to hand over the plant demonstrated excellent performance and electricity savings of up to 40% compared to the adjacent existing AS plantThe municipality recognised that additional treatment capacity will be needed in the near future as the town grows and hence wanted a plant which could be easily expanded. The HYBACS® process is ideally suited to a modular scale up and the new HYBACS® plant has been designed to enable a cost effective second phase extension to 7ml/d per day by the installation of an additional 2 SMART units and 1 additional clarifier (no additional aeration zones or aeration equipment needed)
