Critical Reservoirs Struggle To Rebuild

Tshwane’s water supply system is showing encouraging improvements, but recovery remains fragile and uneven across Regions 1, 3, 4 and 6. While several reservoirs have stabilised, others remain critically low. High consumption and limited incoming supply continue to slow recovery, making reduced water use essential to protecting these gains and improving supply to affected communities.

Region 1: Water supply has largely stabilised across the region. The Mabopane Main system is improving, with its distribution reservoirs maintaining stable storage levels. However, the Soshanguve L system remains under pressure, particularly in high-lying areas supplied by the Soshanguve L Tower. Klipgat and Winterveld reservoirs remain relatively stable, although customers in high-lying areas will experience low pressure as high consumption in lower-lying areas limits the water reaching them

Region 3: Region 3 remains the most severely affected. Klapperkop Reservoir is almost depleted, while Heights High Level Reservoir remains critically low, limiting their ability to supply downstream reservoirs. Atteridgeville Low Level and several central reservoirs have reasonable storage, but require sufficient incoming water to sustain supply. Carina Street Reservoir is approaching critically low levels, while Findlay Reservoir has stabilised.

Region 4: Atteridgeville High Level Reservoir has recovered to a satisfactory level. Bakenkop, Brakfontein and Doornloof reservoirs continue to improve, while Louwlardia has shown significant recovery. Rooihuiskraal and The Reeds have moderate storage levels and are improving. These gains remain vulnerable to sustained high consumption

Region 6: Garsfontein Reservoir has moderate storage, while Elardus Park and Moreleta have comparatively better levels. Mamelodi, Derdepoort and Parkmore Low Level remain under pressure and are being closely monitored. Mamelodi R3 and R4 reservoirs are stable at low levels, leaving little reserve to meet any increase in demand. Reduced consumption is vital to sustaining recovery: The network remains vulnerable, particularly in Region 3, parts of Region 6 and recovering systems in Region 4. In several critical systems, consumption continues to exceed the rate at which water can be replenished. This prevents reservoirs from rebuilding the reserves needed to sustain reliable supply. The city and Rand Water continue to coordinate supply balancing, controlled restrictions and measures to reduce demand. These interventions support recovery, but their success also depends on customers reducing consumption. All customers, including those whose supply remains uninterrupted, are urged to use water only for essential needs, repair leaks promptly and avoid watering gardens, washing vehicles with hosepipes or filling swimming pools. Every reduction in consumption helps reservoirs recover and improves the prospect of reliable supply for affected communities
