The author offers guidelines for establishing a distribution system maintenance program: 1) use main information systems; 2) optimize water quality in the treatment plant; 3) use a fixed flow direction pattern in the network as long as possible; 4) research the useful life expectancy of pipe materials and predict replacement dates; 5) every 10-12 years, renovate the system to maintain the transport function; 6) accept reactive maintenance on service connections and valves; and 7) formulate replacement criteria based on costs and interruption time. This primer offers detailed discussion of each point.
