The Department of Water and Sanitation (DWS) in the Western Cape continually provides update to residents on the current status of water availability across the province. According to Ms Ntombizanele Bila-Mupariwa, DWS Western Cape Provincial Head, the Western Cape Water Supply System (WCWSS) indicates a slight decrease in overall water storage levels, now standing at 91.44%, reflecting a marginal decline of less than 1% compared to last week. However, this marks a substantial decrease when compared to the same period last year, when the system was at 100% capacity and overflowing.
The Olifants/Doorn River Catchment, which supports the agricultural activities and some Local Municipalities in the West Coast Region, stands at 92%. Ms Bila-Mupariwa highlighted that the Clanwilliam Dam, which had previously been lowered to facilitate ongoing construction, is replenishing. Current dam levels are at 90%, and the department is monitoring the levels and will keep the communities updated. Water users relying on this system are therefore assured of access bulk water supply.
The Theewaterskloof Dam, the largest dam in the province and the WCWSS, is currently at 85%, compared to 100% at this time last year.
Other key dam levels as of 16 September 2025 are as follows:
- Berg River Dam – 99.62%
- Brandvlei Dam – 77.59%
- Gamka Dam – 36.53%
- Bulshoek Dam – 91.90%
- Ceres Dam – 100%.
The overall provincial average, covering all 44 monitored dams in the Western Cape, has remained stable at 84% since last week. As the province enters the warmer spring and summer seasons, typically associated with increased water demand due to higher temperatures and outdoor activities, residents are urged to continue using water wisely.
“Spring and summer are particularly water-intensive seasons due to the predominantly hot weather conditions and most towns in the Western Cape are tourist destinations. It is important for residents to conserve this valuable resource and be mindful of their consumption. Considering South Africa’s semi-arid climate and the growing impact of climate change, we wish to emphasize the importance of responsible water use,” says Ms Bila-Mupariwa.
The Department continues to monitor dam levels closely and will provide regular updates to ensure the public remains informed.
