Johannesburg Water’s (JW) Conservation and Demand Management Programme (WCWDM) aims to reduce demand by 37,123 million litres per annum.
JW said through its technical interventions, and this new initiative, it hopes to tackle water losses.
Logan Munsamy, senior manager for WCWDM and Technical Metering, said “the organisation plans to install smart pressure controllers on key network zonal PRVs. These controllers will help manage pressure more effectively, reducing the incidence of bursts and leaks. Together, these interventions aim to lower high pressures in the system, ultimately decreasing minimum night flows and water losses.”
He also said another initiative, known as the Pressure Reducing Valve (PRV) Programme is essential in the water supply system, installed inline within pipelines.
Both programmes will now regulate downstream pressure to ensure consistent water supply over long distances, even through pipes of varying diameters.
Each region in Johannesburg Water’s Networks Department conducts PRV maintenance with a dedicated special services team, led by an operations manager and skilled artisan fitters, responsible for both reactive and preventative maintenance.
