Metro upgrades old pipes in Silverton to mitigate water loss

Tshwane metro has embarked on a multi-million rand project to curb the scourge of water losses, and persistent pipe bursts by replacing the old dilapidated piping system in Silverton, east of Pretoria.

This much-needed refurbishment, according to the metro, is conceived to thwart the disruption of water loss, and water wastage which has bad financial implications for the city.

According to the project manager Themba Mankanyi, old pipes which are frequently leaking and bursting are to be replaced in this four-month project.

Makanyi said they are currently working on Brandwag Street, digging out old pipes and installing quality pipes which are not prone to breakage or leaks.

Metro spokesperson Lindela Mashigo said the scope of work entails the replacement of approximately 1 765m of worn-out water network pipeline.

He said the project will focus on installing isolation valves, valve boxes, water meter connection pipes, fire hydrants, valve chambers where required and all re-instatements in Brandwag Street in Silverton and Meyerspark.

The project commenced on August 23 and will cost R7.5-million.

“The estimated amount includes the construction cost, professional engineering fees and OHS Agent fees.”

Mashigo added that the delay in the commencement of the works was due to challenges experienced with the contractual obligations, social facilitation, identification and approval of the site camp location.

“The change in pipe material design after a decision was taken to rather make use of trenchless technology as far as possible instead of open excavation method also impacted the commencement date.”

He said after work has been completed it is estimated that approximately 3 200 kilolitres per day will be saved.

“This will mean no further leaks and/or pipe bursts along the replaced pipeline and the water supply should be uninterrupted.”

According to Mashigo, the completion date of the project is estimated to be at the end of January 2025.

“The initial construction period is four months. However, an extension of time claim is expected due to the delays.”

He added that a temporary pipe with connections is provided along the pipe route while the existing worn-out water network pipeline is replaced.

“A Community Liaison Officer is also appointed to communicate with all affected residents throughout the construction period to ensure that any problem experienced can be attended to as soon as possible.”

Mashigo told Rekord the construction method that the contractor uses during construction and the type of material used must be per the design and must comply with the standards and specifications of the city.

“A full-time professional resident engineer from the appointed consulting engineering firm and the City of Tshwane’s System Inspector are supervising the construction work and are executing quality control.”
