This article discusses how the Norwich (Connecticut) Department of Utilities solved a nagging rusty‐water problem. A 2‐inch plastic service line was tapped into the top of a 6‐inch dead‐ended cast iron main about 400 feet from the terminus of the cast‐iron pipe. The 400 ft of dead‐end main now accumulates rust particles, allowing the 2‐in line to flow clear. Semi‐annual hydrant flushing rids the system of all iron before it backs up the 6‐in dead‐end into the 2‐in service main.
