All fire hydrants shall be identified with a pavement marker, Stimsonite Model C80. The marker shall be placed on the side of the street of the hydrant, four feet inside of the solid white line denoting the edge of roadway. The marker shall be installed using a two-part epoxy adhesive as manufactured by Ennis Paint Company or approved equal. Fire hydrant branches (from main to hydrant) shall be not less than 6 inches inside diameter. Each branch shall be provided with a gate valve located as close as possible to the main. Valve box top shall be set to grade. Hydrants shall be located near road lines with pumper discharge nozzle facing the roadway. Hydrants shall be laid as to minimize their vulnerability to traffic. Fire hydrant extensions shall not be allowed. 11
Hydrants shall be placed within 15 feet of the street of paved area when possible, and shall be no closer than 5 feet from the edge of the street or paved area and/or back of curb.

All service line taps shall be installed in accordance with the construction details of this manual. Services shall have a minimum of 30 inches cover including at ditches. All service crossings under roadways shall be installed in a casing not less than 36 inches between the top of the pavement and the top of the casing. Water service taps shall not be placed under pavement including roads, driveways, parking lots and sidewalks. Services shall not exceed 100 feet to the meter. Meters should generally be placed at the property line. In developments where the property line is not clearly defined (such as at condominiums) the meter should be placed for ready access. Meters shall not be placed in areas that can be fenced, such as backyards, under any circumstances. Services crossing under parking lots shall have their meters placed prior to the crossing so that the Department is not responsible for the service lines. All valves shall be placed according to plan unless relocation is mutually agreed to. Record or as built drawings shall reflect the actual location and size of all mains, fittings, hydrants, services and valves. All taps must be at least 18 inches from a fitting or bell. 12. Connection To Existing System a) Tapping Tees and Valves Tapping sleeves shall be #304 stainless steel with flanged outlets. Tapping valves shall be resilient seat type with a flanged joint on the inlet side and a mechanical joint on the discharged side of the valves. Tapping valves shall have a 2 inch operating nut. Working pressure rating shall not be less than 200 psi. Gaskets between the flange faces of the tapping sleeve and tapping valve shall be 1/8" minimum thickness of BUNA N gasket material. b) Size on size taps Taps may be made on the same size main only when the main to be tapped is AWWA C900, C905 or DIP. c) Installation 12
