Bellville Wastewater Treatment Works (WWTW)

Construction of the civil and structural works for the MBR Extension at the Bellville Wastewater Treatment Works, in Bellville in the Western Cape. The Bellville plant will feature the largest membrane bio-reactor (MBR) in the country; and its capacity will increase by 20 Ml/day, to 70 Ml/day (average dry weather flow – ADWF). The 20 Ml/day MBR will be separate from the existing activated sludge plant. Hence, during the construction period, the existing plant will not be impacted upon. In addition, the design and build contract, including all mechanical and electrical works, will supply a new inlet works for the MBR plant, new biological reactors and six membrane trains. A new sludge dewatering facility will also be supplied, as well as an upgrade of the existing electrical and control systems infrastructure at the Bellville WWTW. Value: R187 million
