(B) Water mains.
(1) In residential, business, and industrial areas, water mains shall have a minimum nominal diameter of eight inches. For diameters of eight inches, ten inches, or 12 inches, water mains shall be pressure class 350, or an approved equal, ductile iron pipe manufactured in the U.S. in accordance with the latest revision of ANSI/AWWA C151/A21.51. Each pipe shall be subjected to a hydrostatic pressure test of at least 500 psi at the point of manufacture.
(2) Pipe shall have standard asphaltic coating on the exterior. Pipe shall also have a cement mortar lining on the interior in accordance with ANSI/AWWA C104/A21.4, or latest revision. Water mains with nominal diameters of 14 inches or larger shall be a pressure class approved by the city utility.
(C) Hydrants. Water hydrants shall be the same as those presently used throughout the city with two two and one-half inch openings and one four and one-half inch pumper nozzle, all national standard thread. Hydrants shall be placed along the streets not more than three feet back of the curb line, at intersections whenever possible. The maximum distance between hydrants and valves in residential areas shall be 450 feet and in business and industrial areas shall be 350 feet. Ports or openings shall be elevated between 26 and 34 inches above grade and be turned facing the street.
(D) Sewage system. Sanitary house connection sewers shall be no less than four inches in diameter. If less than six inches, PVC-ASTM-3033-3034 must be used. Sanitary local sewers to serve a subdivision, or a part thereof, shall be a minimum of eight inches, inside diameter.
(E) Water supply interconnections. There shall be no cross-connection between a public and private water supply system and a sewer which will permit the passage of any sewage or polluted water into the water supply. Sewers shall be kept removed from water supply sources and structures.
(F) Relation of sewers to water mains. A minimum horizontal distance of ten feet shall be maintained between water and sanitary sewer lines servicing any property. At points where sewers cross water mains, the sewer shall be constructed of cast iron pipe, or encased in concrete for a distance of ten feet in each direction from the crossing, measured perpendicular to the water line. This will not be required when the water main is at least two feet above the sewer.
(G) Valves. Water main valves shall be located at every street and cul-de-sac intersection and before each hydrant.
