Plans to boost water supply in Midrand area with construction of Carlswald reservoir & upgrade water network

As part of its mandate to maintain and upgrade water infrastructure and provide services, Johannesburg Water has a reservoir and water pipeline project to upgrade the water pipeline network in Carlswald, Midrand, and improve water storage to communities.

The purpose of the Carlswald Water Pipeline project is to upgrade the water pipeline network in Carlswald, Midrand, and is a prerequisite to the bigger plan to build the new Carlswald Reservoir.

The pipeline project is progressing well and is at the Environmental Assessment stage as well as Public Participation Process stage. A positive environmental authorisation was granted in September 2024.

The 20 megalitre-Carlswald Reservoir Detail Designs have been completed. The construction of the reservoir will begin once a contractor is appointed. The process is currently at the procurement stage.

“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’s General Manager: Capex, William Chitsa.

The proposed pipeline is approximately 5.1km in length and will start on Walton Road and end just outside the Blue Hills Country Estate entrance and 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.”
