Bushkoppie Wastewater Treatment Works

 

Project Value: R 72.6 Mil

Client: Johannesburg Water

Completion Date: 2016

Consulting Engineer: Hatch Goba

 

Eigenbau recently completed a contract for Johannesburg Water to replace the fine bubble diffused aeration system at Bushkoppie WWTW. The contract consisted of replacing the old ceramic dome diffusers with 9″ EPDF disc diffusers. The plant has four reactors, 100m x 50m. Each of the four biological reactors were drained, the old diffused aeration system removed, and then a new system installed.

Eigenbau installed 16 320 new diffusers in each reactor, complete with lateral pipes, down pipes, isolation valves and ancillary equipment. We designed and implemented a temporary pumping system so that the plant’s settling tanks remained in operation whilst we took a biological reactor offline.At the end of the contract there was a saving that was spent on improving the performance of the plant, including degritting channels and settling tanks.
