JB Marks Municipality Coordinates with Water Department on Crucial Boskop Dam Canal Overhaul
Due to structural repairs on a major supply canal, the local authority has implemented emergency routing measures to prevent widespread shortages, though residents are being urged to exercise caution regarding their consumption.
Department of Water and Sanitation Imposes Strategic Shut of Boskop Dam Right Bank Canal
A critical, scheduled closure of the Boskop Dam Right Bank Canal is underway following a joint directive from the Department of Water and Sanitation (DWS) and the JB Marks Local Municipality. The shutdown, required to carry out essential "corrective maintenance," began on Sunday, 8 November 2026, at 07:00 and is slated to continue until Friday, 13 November 2026, at 07:00.
The Right Bank Canal, which has historically functioned as a primary conduit for conveying untreated water from the Boskop Dam south toward Potchefstroom’s municipal purification works, will be entirely dewatered to allow engineering teams to perform repairs. The 120-hour maintenance window is designed to address wear-and-tear and prevent more serious, unmanaged failures along the aging concrete-lined route.
To sustain supply, the DWS has diverted the bulk of the raw water flow into the Boskop Dam Left Bank Canal. However, municipal engineers have raised concerns, noting that the Left Bank Canal has a smaller carrying capacity than the western channel, which could result in a significant bottleneck in raw water delivery.
Mitigation Measures and Increased Relying on Potchefstroom Dam
To offset the capacity limitations of the Left Bank Canal during the repair window, the municipality is implementing a contingency plan to draw additional resources from alternative storage sites. Specifically, the local authority has been "strongly urged" to maximize its water extraction from the nearby Potchefstroom Dam.
The Potchefstroom Dam, situated closer to the town's northern boundary, will serve as a vital buffer to ensure that the municipal water treatment plant can continue operating at necessary volumes. This supplemental extraction is meant to stabilize the network’s pressure and prevent high-lying areas from experiencing outages.
However, because both the Boskop and Potchefstroom dams are interconnected parts of the Mooi River Government Water Scheme, the redirection requires careful monitoring to ensure that balancing these extractions does not trigger ecological or volumetric strain. The municipality, therefore, expects that while these maneuvers should mitigate the worst of the disruption, localized pressure drops remain a possibility if overall consumer demand surges.
Community Urged to Protect Reserves During Transitional Week
Local administration has emphasized the need for active cooperation from both residential and commercial consumers throughout the week-long maintenance period. Households, schools, and businesses are being asked to suspend non-essential water uses, such as garden irrigation, filling pools, and washing vehicles, to minimize pressure on the constrained supply.
"The Department appreciates your cooperation and understanding," the municipal communications team stated, assuring residents that both local and national technical crews are working around the clock to ensure the Right Bank Canal is safely recommissioned by Friday morning.
Should any unexpected shortages or major pressure losses occur outside the expected boundaries, the municipality's communication unit has committed to issuing real-time alerts. Regular updates are being posted across the municipality’s official portals, and the public is encouraged to report any major leaks or burst pipes promptly to assist in conserving the available supply.
This temporary diversion highlights the ongoing challenges of maintaining critical, mid-century water infrastructure, and the necessity of coordinated efforts between local government and national departments to guarantee long-term service reliability.
