Enviros Consulting landfill leachate treatment experts have successfully completed the commissioning of the new Leachate Treatment Plant for eThekwini Municipality's solid waste Disposal department (Durban Solid Waste - DSW).
The plant is treating leachate collected from the Buffelsdraai Landfill, which is a large new landfill located to the north west of the city. The site opened in May 2006 and receives the waste-stream that was originally accepted by the now closed La Mercy landfill site. The site will also accept waste previously disposed at other DSW landfills, including the large Bisasar Road Landfill.
The leachate treatment plant is planned to be completed in two stages with a treatment capacity of approximately 200 cubic metres per day, of which half has now been installed and commissioned.
The plant is the third biological treatment plant using a nitrification process similar to the many other Enviros plants, which Enviros has designed and commissioned in South Africa. It follows the commissioning of the Vissershok Leachate Treatment Plant (Cape Town City Council) and the Mariannhill Leachate Teatment Plant (Durban Solid Waste).
The leachate treatment plant protects the local river from contamination by leachate, which would if not treated, pollute the watercourse. Even if present at extremely low levels untreated leachate can cause taste problems in water later abstracted and treated for potable (drinking) water supplies.
The plant includes a reed bed for final water quality polishing, and will provide water for irrigation and for dust suppression.
