Johannesburg Water’s work to upgrade its water pipeline network in Carlswald, in Midrand, a prerequisite to a bigger plan to build the new Carlswald reservoir, is progressing well.

The Carlswald Water Pipeline project is at the environmental assessment stage, with a positive environmental authorisation granted in September 2024, as well as in the public participation process stage.

The proposed 5.1 km pipeline, which will start on Walton road and end just outside the Blue Hills Country Estate entrance, will service current and future developments in the area.

“The pipeline is required to implement the new Carlswald reservoir supply zone project, to augment the Errand reservoir – which does not have sufficient capacity. This will in turn supplement and improve storage capacity at the Errand system,” Johannesburg Water said in a statement on Wednesday.

The detailed designs for the planned 20 megalitre Carlswald reservoir have been completed, and the project is currently at the procurement stage, with construction set to start once a contractor is appointed.

“The building of this new Carlswald reservoir will improve water storage, as well as ensure an uninterrupted supply of water in the area. There is constant urban development in the city (more so in Midrand/Blue Hills/Kyalami areas) and Johannesburg Water needs to ensure that our infrastructure and service delivery matches the growing population,” says Johannesburg Water general manager: capital expenditure William Chitsa.

The communities that will benefit from the project include Barbeque Downs extensions 47, 38, 22, 35, 49, 9, 19, 33, 27, 45, 21, 17, 12, 46, 48, 32, 36, 5, 24, 1, 25, 7, 13 and 28; Kyalami Park; Kyalami Heights; Kyalami AH; Kyalami AH extension 1; Kyalami extensions 2, 3 and 14; Kyalami Estate extension 17; Kyalami Gardens extensions 1, 13, 14, 15, 16, 12, 19, 21, 22, 23 and 24; Beaulieu; Blue Hills extension 8 and 9; Willaway; Willaway extensions 2, 5, 6, 7, 9, 10, 11, 12, 13 and 14; Glenferness AH extensions 1 and 2; Glenferness AH; Treesbank AH; as well as Plooysville AH.
