Johannesburg Water (JW) will be rolling out smart pressure controllers at 28 high-consumption reservoirs and towers.
The local water utility said the controllers are among several initiatives purposed to conserve water by reducing water losses.
The gadgets are expected to throttle reservoir outlets in order to reduce minimum night flow losses and build reservoir capacity overnight.
Logan Munsamy, Senior Manager of Water Demand Management and Technical Metering, at JW, said high-consumption Pressure Reducing Valves (PRV) zones will be prioritized in the rollout.
“Smart controllers will help manage pressure more effectively, reduce the incidence of bursts and leaks. Together, these interventions aim to lower high system pressure, ultimately decreasing minimum night flow losses.”
So far, some 53 pressure controllers were installed since 2023.
Another 306 are expected before end of September this year.
