Winter precipitation has provided a significant boost to water security in the West Cape, bringing major water supply systems closer to the critical threshold of 80% and causing a noticeable recovery in the province's largest reservoirs.
Water Supply Status
According to the latest data from the Department of Water and Sanitation, the Cape Town water supply system reached 77.63% capacity this week, a confident increase compared to 76.94% last week. The overall state of dams in the province reflects this positive trend, rising to 78.84% from 77.97%, as the region's catchment areas continue to receive regular seasonal rains.
Largest Reservoirs
The massive Theewaterskloof reservoir is leading this recovery, serving as the basis for municipal supply in the region and increasing to 77.78% capacity, which sharply contrasts with the 63.06% recorded at the same time last year. Operational flexibility was further enhanced by smaller high-altitude reservoirs such as Steenbras Upper, which are officially overflowing at 102.17%, and Wemmershoek, which is on the verge of overflowing at 99.95%.
Recovery in Other Areas
Meanwhile, the Olifants-Doorn catchment area shows impressive improvement: the Clanwilliam dam now holds 96.00%, more than double the dismal 41.42% registered the same week last year. Even the drought-affected Garden Route is seeing relief, as the Akkerkloof dam in Knysna reached 41% thanks to active pumping from its balancing systems.
Calls for Water Conservation
Despite the very encouraging figures, water services strongly urge residents to remain vigilant. The Regional Manager for the West Cape, Ntombizanele Bila-Mupariva, expressed strong satisfaction with the stable growth but emphasized that water conservation remains a top priority. Bila-Mupariva noted that while the dam levels are very encouraging, the ultimate goal is to reach full capacity before the dry summer months, reminding residents that water usage restrictions will only be reviewed as the system approaches maximum storage.
