3.6 System Reliability; Looping

Looped water mains are desirable for fire flow, system reliability during maintenance, water quality and shall be completed wherever possible. Dead ends shall be avoided, except as needed to provide for future service, cul-de-sacs, and fire hydrants. An extension to provide for future looping may be required, even if such extension is not required to serve adjacent properties. Dead-end extensions shall be provided with a standard blowoff assembly, see PUD standard details for further guidance.
