Underground water pilot launched to serve Joburg’s underserved

In an effort to ensure reliable access to water for residents in underserved areas in Johannesburg, Johannesburg Water has launched an groundwater pilot project to improve supply to these areas.

The project, in partnership with the University of the Witwatersrand’s School of Geosciences, involves the drilling of boreholes and the creation of localised water distribution points.

The pilot phase targets nine informal settlements across the Deep South (Region G). According to Johannesburg Water, the project is first of its kind to improve water supply for underserved communities throughout the City of Johannesburg.

Johannesburg Water’s Managing Director, Ntshavheni Mukwevho, said this innovative project represents a major milestone in addressing long-standing water supply challenges in underserved communities across the City of Johannesburg.

“By tapping into underground aquifers, Johannesburg Water aims to supplement existing water infrastructure and ensure that all residents—regardless of where they live—have consistent access to safe water,” he said. 

Underground water as complementary source to City of Johannesburg’s bulk water supply

Johannesburg Water said the goal is to test the viability, sustainability and scalability of groundwater as a complementary source to the city’s bulk water supply, particularly in areas with limited or no formal infrastructure.

Work has begun at the Water Works, Marikana, and Kokotela areas, and next, the project will move to the Phumla Mqashi and Narens Farm.

The Deep South is an area with a high volume of underserved homes and illegal water connections, which has put a strain on the system due to the demand exceeding the available supply and capacity.

This initiative has been hailed by relevant players in the water sector. Sustainable Drop Projects said the initiative is a step towards equity and the partnership is uniquely positioned to turn these challenges into a benchmark for safe and sustainable groundwater use.

“We are encouraged by the involvement of Wits’ Geosciences expertise, which gives us great confidence. As you are aware, the geological context of the Deep South requires careful navigation. The potential presence of dolomitic aquifers introduces specific risks, such as sinkhole formation from over-abstraction and water quality variability, which could impact community safety and project sustainability.

“We trust that the rigorous pilot phase will prioritise detailed geohydrological surveys, sustainable yield determinations, and continuous groundwater monitoring as core components. This scientific, precautionary approach is essential for managing risks and ensuring the success of the project,” said Sustainable Drop Projects.

Keletso Mbele, community leader for Water Works area said they are truly grateful to Johannesburg Water and all its partners for this project. “We will ensure that we safeguard the project, as water is life and is also a scarce resource,” she said.
