How does flushing the water distribution system work?
The Public Works Department has an ongoing program of flushing the distribution pipes to help ensure that they are kept clean. Otherwise, rust and sediment would cling to the pipe walls. Flushing is done by opening fire hydrants and letting the water rush through the pipelines at a higher-than-normal velocity. The water being moved through at a high velocity breaks loose the sediment that may be present. The water is flushed until it becomes clear and cold. During this process, there is a sufficient amount of chlorine residual present for disinfection.
