The project is the construction of the Western Highveld Bulk Water Supply Scheme, Work Package 1. It aims to improve potable water security across portions of Gauteng, Limpopo, and Mpumalanga by constructing pipelines, pump stations, reservoirs, and associated infrastructure. The project addresses water supply infrastructure backlogs within the Mathanjana Magisterial District (MMD) and Rapotokwane settlements. Water will be sourced from Rust De Winter Dam surface water. The scheme includes a 51.5 km gravity bulk pipeline (19.4 km of 500 mm and 32.1 km of 400 mm diameter welded steel pipeline) from the command reservoir to various villages. The project is located within DR JS Moroka Local Municipality, Nkangala Region, Mpumalanga.
