The City is replacing more than 1000 metres of ageing fibre-cement water pipes in Southfield with plastic ones.
The R3.4 million project to replace the 100mm and 150mm diameter fibre-cement water pipes in Wynsam Way and Gull and Legas roads is part of the R836.6 million budgeted for a citywide programme to replace water and sewage pipes and reduce pipe bursts and leaks, says the City.
“In Southfield, the declining condition of pipes due to age started causing more frequent bursts. This was the main driver for replacement. New and improved 110mm and 160mm diameter uPVC pipes are a cost effective alternative and manufactured to last at least another 50 years,” said a City statement.
Excavations and installations started in February, and the project is scheduled to be completed by June, the City said.
Replacement is being done using the open-trench excavation method, which requires excavation of roads and pavements to lay down pipes.
Teams use several methods to lay, install and join pipes; secure pipe fittings; and replace valves and hydrants. Then the system is flushed and the water pressure is tested.
“Replacing pipes systematically, reduces the recurrence of disruptions in the future. It also gives us an opportunity to plan ahead and prepare a budget for rehabilitation, based on the most recent projections of usage and wear and tear. However, external factors such as vandalism and population growth also have a direct impact on the durability of water and sanitation infrastructure,” said mayoral committee member for water and sanitation Zahid Badroodien.
