A. Any person or developer wanting to connect water main extensions to the existing City public water distribution system must submit construction plans and specifications to the Director, pay established fees and charges, and receive permits approved by the Director before any construction of the water main extension commences.

B. The Department will not perform field engineering or prepare detailed plans and specifications for water main extensions and associated appurtenances for any owner or developer. The owner or developer is responsible for all costs for hiring a civil engineer registered in Arizona to perform all work. The owner or developer must pay all costs to design, permit, and construct the water main extension, including any costs of acquiring rights-of-way and easements, preparation of as-built plans, and the Department’s inspection of construction.

C. Any water main extension must be sized for adequate service during peak demands and fire flows, as determined by the Director. The Director will determine the necessary layout of public water mains.

D. Each service connection must have a flow rate of at least three gallons per minute, with a minimum residual pressure of 40 pounds per square inch at the meter.

E. If public booster pumps or pressure reducing valves are necessary to maintain appropriate water pressures in mains because the development to be served with the main extension is near the hydraulic gradient of the distribution system of the City service area, the developer must construct at the developer’s expense the necessary facilities and must meet City design standards.

F. All water main extensions, service connections, public booster pumps, pressure reducing valves, and all other water distribution facilities constructed by developers pursuant to this article upstream of points of service delivery become and remain the property of the City on acceptance of the facilities by the City. The City assumes ownership, maintenance and operation of the facilities on acceptance.

G. If the finished floor elevation of a structure that receives water service is above the designed pressure zone’s top elevation boundary, the developer must construct a private booster-pump station and associated storage facilities to provide adequate pressure for the required flows to the property. If the finished floor elevation is below the designed pressure zone’s low elevation boundary and the static pressure at the meter exceeds 80 pounds per square inch, the developer must install a pressure reducing valve to decrease pressure adequately for the required flows. Any stations, facilities or valves must be located downstream of the point of service delivery and remain privately owned, operated, and maintained at the property owner’s sole cost and expense.
