Why is water main flushing needed?
Water mains (pipes) need to be flushed to remove sediment from corrosion that has built up over years of use. The pipes are cleaned by forcing water through at high speeds. Flushing removes the sediment that can cause water to appear dirty or discolored, and may also improve the water's taste.
