Johannesburg Water has completed another successful major water pipe replacement project.

The project, in Blairgowrie, marks a significant milestone in the City of Johannesburg’s ongoing efforts to enhance water security, reduce leaks and water wastage, and provide a more sustainable water supply for residents. It formed part of Johannesburg Water’s broader water infrastructure renewal programme, focused on replacing ageing and frequently failing asbestos cement pipelines with modern, high-quality, corrosion-resistant modified polyvinyl chloride (MPVC) pipes. These upgrades were designed to reduce water losses, ensure consistent pressure, and minimise disruptive bursts.

Johannesburg Water’s, and capex project manager, Tsakani Ngobeni explained that because MPVC pipes are lightweight, they are much easier to install, more durable, and extremely resistant to corrosion and cracking. “Compared to asbestos, MPVC pipes are far less harmful to the environment and human health because they don’t emit toxic fibres. For water and sewerage infrastructure projects, it is typically a more durable, safe, and sustainable option.”

The project involved the replacement of 750m of pipeline and included the installation of fire hydrants, valves, and domestic water meters.

Key outcomes of the project include:

• Improved reliability of water supply to households and businesses in Blairgowrie,
• Reduced likelihood of pipe bursts and leaks, lowering emergency repair costs and disruption of water supply,
• Enhanced water pressure management, supporting day-to-day usage needs, and
• Long-term sustainability benefits, helping preserve precious water resources.
