NORTH WEST — Critical Bloemhof Dam rehabilitation efforts are officially underway as the Department of Water and Sanitation (DWS) begins a controlled water release to facilitate essential upstream slope repairs. The strategic infrastructure project aims to address recent slope damage while maintaining regional water security and ensuring public safety.
According to the DWS, engineering and technical specialists are maintaining continuous oversight of the situation. A contracted team is already on-site, executing necessary maintenance preparations under the direct guidance of departmental experts. Currently, the dam is operating at an elevated level of 109%. Dams across the integrated Vaal River System are being managed at these higher levels to guarantee water security, while remaining vigilant about potential flood management needs.
For the physical rehabilitation of the upstream slope to commence, a completely dry working area must be established. To achieve this, the DWS announced it will steadily release water to bring the dam down to its full supply level of 100%. A release rate of 400 cubic meters per second (m3/s) will be implemented. The department estimates that reaching the target level will take approximately one to two weeks.
Addressing public concerns, the DWS explicitly assured communities and stakeholders that the planned water release will not result in downstream flooding. The controlled discharge is carefully calculated to mitigate any adverse impacts on areas situated below the dam.
Technical teams are currently conducting further analyses to find the optimal balance between dam safety, water security, and flood management. However, the department emphasized that structural integrity and dam safety remain the absolute priority. Should the Dam Safety Office issue a directive to maintain the water at a specific level, the DWS is legally obligated to comply and operate the Bloemhof Dam accordingly.
Reaffirming its dedication to transparent communication, the DWS promised to keep all affected water users and stakeholders informed with regular updates as the maintenance program evolves. The department concluded by assuring the public that every possible effort is being made to finalize the repairs swiftly and safely, ultimately safeguarding the long-term resilience of this vital strategic water resource.
