21.02.035 Water system requirements.

(1) New or Replacement Water Mains for Community Systems with 15 or More Connections.

(a) New or replaced water mains shall be a minimum of eight inches in diameter for dead-ends and six inches for circulating mains (grid or loop systems). For dead-end cul-de-sacs, a six-inch diameter main need only extend to the last required fire hydrant if the distance is 300 feet or less, otherwise, an eight-inch diameter main is required to the last required hydrant. Smaller water lines may be installed thereafter to the remaining residences.

(b) Hydrant leads less than 50 feet may be six inches in diameter. A dead-end main that extends across a street only for the purpose of serving a hydrant shall be of a size capable of providing the required fire flow, but not be less than six inches in diameter. All mains shall have hydrants and/or tees and valves installed to conform to this regulation. The County Fire Marshal, after consultation with the local Fire Department or district, may waive this requirement if the water system is unable to provide sufficient fire flow at the time of water main installation. In such cases, the water system owner shall commit to a compliance date to be approved by the Fire Marshal by which fire flow shall be available and hydrants installed.

(c) The water system shall be capable of delivering the required fire flow at a minimum hydrant pressure of 20 psi while maintaining normal system peak instantaneous demands. Water mains shall conform to current AWWA specifications.

(d) The minimum fire flow requirements for one- and two-family dwellings (R-3) shall be 500 GPM for 45 minutes.

(2) Fire Hydrant Specifications and Installation.

(a) This standard shall apply to all new fire hydrant installations and when existing hydrants are replaced. All hydrants shall conform to current AWWA specifications for traffic model fire hydrants:

(i) One hundred fifty psi working pressure.

(ii) Three hundred pounds hydrostatic test.

(iii) One five-and-one-quarter-inch main valve opening.

(iv) One four-inch NST pumper port (check with local fire district to determine if a five-inch Storz fitting is required).

(v)  Two two-and-one-half-inch NST hose port.

(vi) One one-and-one-half-inch pentagon operating nut – open left.

Main valve shall be compression-type, opens against pressure, and will remain closed should the hydrant be damaged or broken. Hydrant shoe or inlet may be flanged, AC pipe, or mechanical joint. Hydrant shall be furnished with two drain ports to ensure rapid and complete drainage of hydrant barrel to eliminate all danger of freezing. (Refer to the AWWA manual, Installation, Field Testing and Maintenance of Fire Hydrants, for detailed specifications.)

(b) There shall be an auxiliary gate valve installed to permit the repair and replacement of the hydrants without disruption of water service. Gate valves shall be in conformance with the latest specifications of AWWA and be iron body, bronze mounted with two-inch square operating nuts that open left. End styles shall be flanged, mechanical joint or ring-tite.

(c) Hydrants shall be installed plumb and be set to the finished grade. The bottom of the lowest outlet of the hydrant shall be no less than 18 inches above the finished grade. There shall be no less than 36 inches of clear area about the hydrant for operation of a hydrant wrench on the outlets and on the control valve. Hydrants shall be accessible for Fire Department pumpers. The pumper port shall face the street. Where the street cannot be clearly defined or recognized, the port shall face the most likely route of approach and the location of the fire truck while pumping, as determined by the local Fire Department.

(d) Hydrants shall not be obstructed by any structure or vegetation, or have the visibility impaired for a distance of 50 feet in the direction of vehicular approach to the hydrant. Fire hydrants subject to vehicle damage (i.e., those located in parking lots) shall be adequately protected.

(3) Fire Hydrant Location and Spacing.

(a) Where new water mains are extended along streets where hydrants are not needed for protection of structures or similar fire problems, fire hydrants should be provided at not less than 1,000-foot spacing to provide for transportation hazards. Spacing shall be measured by the pathway required for the Fire Department to lay the fire hose. This spacing shall be determined by the Clallam County Fire Marshal and the local fire district.

(b) The location of all water mains, fire hydrants, and valves to be installed shall be properly and accurately marked on identifiable plans or drawings. Three copies of all plans or drawings shall be furnished to the Clallam County Fire Marshal. Location of hydrants shall be determined by the Clallam County Fire Marshal and the local fire district.

(c) The average spacing between fire hydrants for other than one- or two-family dwellings (R-3) in short plats and subdivisions shall not exceed that listed in Table A. Regardless of the average hydrant spacing, no portion of a building shall be farther from a hydrant than the distance listed in Table A. Distances shall be measured along approved emergency vehicle accesses and adjacent public and private roads.

(d) For water systems serving one- or two-family dwelling (R-3) buildings in short plats and subdivisions, the distance from the center point of lot frontage to a hydrant shall not exceed 350 feet.

(e) On dead-end streets and roadways not exceeding 600 feet in length and serving one or two-family dwellings (R-3) in short plats and subdivisions, there need not be hydrants located on the dead-end street or roadway if there is an approved hydrant at the intersection.

(f) Hydrants shall be provided along approved emergency vehicle accesses and adjacent public and private roads. When practical, hydrants shall be located at street intersections. The minimum number of hydrants available to a building shall be not less than that listed in Table A.

(g) All new and existing approved hydrants shall be considered available if accessible to the Fire Department by public or private roads or approved emergency vehicle accesses meeting the requirements of Chapter 29.30 CCC.

(h) When possible, hydrants shall be located a distance from the building equal to the building height plus 10 feet and as close to the front access point as practical.

(i) All sprinkler piping installed underground shall be installed by, or under the direct supervision of, a level U State-certified installer.

(j) The authority having jurisdiction shall witness all flushing of sprinkler piping installed underground.

(k) The Fire Marshal and local Fire Department shall be notified of any new hydrant installation and the fire flow available.
