(A) Private Water Mains. Private water mains serving fire hydrants shall be the same size as the public mains supplying the private water system unless hydraulically calculated to provide the minimum required flow and pressure in accordance with nationally recognized standards. In all cases, mains do not need to exceed 10 inches but shall be at least 6 inches in diameter. Alternative designs, based on nationally recognized standards for calculating fire flow demands, may be approved. If the minimum flow and pressure requirements cannot be supplied by a private water supply system, the owner may be required to install a public water supply system and/or multiple points of connection to the public water mains(s).
(B) Valves. Control valves shall be provided to limit the number of private hydrants affected by maintenance, repair or construction. Valves shall be located at street intersections and at no more than 800-foot intervals. Valves shall be provided in each hydrant lead.
(C) Outlet Position. All hydrants shall be positioned so the largest outlet faces the street or fire apparatus access route.
(D) Hydrant Height Above Grade. The center of the lowest outlet cap of fire hydrants shall be at least 18 inches above grade and not more than 24 inches above grade.
(E) Hydrant Specifications. All fire hydrants shall meet the specifications of the most current edition of the Standard Specifications for Sewer and Water Construction in Wisconsin.
(F) Hydrant Colors. All fire hydrants shall have a red barrel. All bonnets are indicated in red with the exception of a dead-end hydrant, which shall have a color bonnet of black. All hydrant caps are color indicated by the gpm as indicated: Green - 1000 gpm or greater; Orange - 500 - 1000 gpm; and Red - 500 or less gpm.
(G) Hydrant Markers. Whenever the location of a fire hydrant may be obscured by its placement, or due to the placement of a building, structure, fencing, grade or land, vegetation, snow accumulation or other obstruction of vision, the Fire Chief and/or the Director of Public Works may require such fire hydrants to be identified and marked with above grade markers. Above grade markers are any devices, approved for use by the Fire Chief and/or the Director of Public Works, designed to promote and enhance the ready identification of fire hydrant locations. Each grade marker should be no less than four feet in height and attached to the hydrant.
