CLANWILLIAM, Western Cape – The R8 billion Clanwilliam Dam Wall Project is rapidly gaining momentum in the Western Cape, with government officials confirming that the massive infrastructure upgrade is firmly on schedule. During a comprehensive mid-week inspection, Deputy Minister of Water and Sanitation David Mahlobo toured the Cederberg Local Municipality site to evaluate construction advancements and engage directly with the crews and local stakeholders driving the development.
Visible Progress on the Ground
The physical transformation of the site is highly visible, with Mahlobo praising the engineering teams for successfully navigating complex construction phases. According to the Deputy Minister, the demolition of specific sections of the legacy dam wall has been fully executed.
Furthermore, foundational work for the new structure is highly advanced. Drilling and grouting for the new dam wall’s foundation are well underway, and concrete placement for the new wall has already surpassed the 21,998 cubic metres mark.
The on-site teams have also successfully delivered several other critical components. These include the preparatory groundwork for the new dam wall, the emergency construction of an upstream coffer dam located at the intake tower, and the completion of the lower spillway section, which was finalized in May of this year.
Overcoming Weather Hurdles and Future Timelines
Mega-projects of this scale inevitably face environmental challenges. Excavation work for the coffer dam’s foundation was temporarily halted last year due to exceptionally heavy rainfall. However, the teams successfully resumed these critical excavations in February.
Looking ahead, the project roadmap outlines a clear path to the finish line. The installation of spillway pipes and the construction of the gallery are scheduled to kick off in November 2026. Following this, the excavation of the tunnel and the intake tower is slated for completion by June 2027, setting the stage for the overall project handover in 2028.
Championing Local State Capacity
A major point of pride for the department is the reliance on domestic expertise. Mahlobo highlighted that the project is a testament to the government’s internal capability to execute complex engineering feats without heavy reliance on foreign contractors.
“I am very pleased because it is not an easy thing, but the team that is working here [from our department] is very experienced… It is an advantage that there is capacity within the State to do these kinds of major infrastructure projects… and that the department was able to bring in experience… mostly South African entities and companies… [This] is one of those particular advantages with which we are very pleased,” Mahlobo noted.
Stakeholder Collaboration and Uninterrupted Supply
Beyond the concrete and steel, the department is acutely aware of the project’s impact on the local community. Throughout the construction, officials are working diligently to balance the massive building effort with the need to maintain uninterrupted water supplies for both agricultural irrigation and domestic use.
During the site visit, Mahlobo held direct engagements with key community groups, including the Clanwilliam Water Users Association and the Lower Olifants River Water User Association. He reassured these groups that the timeline remains intact and urged continued partnership.
“There is still more work to be done on this project, and we encourage the coordination of cooperative governance with stakeholders, as well as the provincial government. Good short-term milestones have been achieved, but there is still a lot of work to be done, and we therefore need to work together to ensure that we reach our targets and finalisation of the project within the planned timeframe,” Mahlobo urged.
A Flagship Investment for the West Coast
Recognized as a flagship water infrastructure investment, the Raising of the Clanwilliam Dam Wall Project is fundamentally designed to secure the long-term water future of the West Coast.
Once the dust settles and the project is completed, the dam wall will stand 13 metres taller than its original height. This structural elevation will expand the dam’s total storage capacity by an estimated 82 million cubic metres of water.
This massive influx of stored water will drastically improve the reliability of supply for regional economic growth, household consumption, and farming operations. The upgrade is specifically positioned to uplift local farmers, households, and historically disadvantaged agricultural operators.
Additionally, the modernized infrastructure will ensure strict compliance with contemporary dam safety standards, particularly during severe flood events, while simultaneously preserving the vital ecological requirements of the Olifants River.
