Stop Flushing Blind: Using Residual Data To Cut Flushing Volumes

Water distribution systems frequently rely on calendar-based flushing routines, discharging substantial volumes of treated water on rigid schedules to guard against chlorine residual decay. Because utilities often lack continuous visibility at vulnerable locations—such as dead ends and low-flow zones—entire distribution lines are flushed indiscriminately to mitigate potential risk. This practice wastes fully treated, chemically dosed water on segments that may still maintain adequate residual levels.

Deploying continuous residual monitoring at key distribution nodes transforms flushing into a precise, targeted maintenance action. Operating with internal flow control allows sensors to deliver accurate readings even in stagnant or low-flow conditions without generating additional sample waste. Instead of flushing on a fixed route, operators can trigger actions only when real-time data indicates a drop in residual, drastically cutting unnecessary water loss and creating clear compliance documentation.
