Any potential hazards should be mitigated using engineered solutions. Confined Space Confined Spaces should be identified in the design phase and eliminated wherever possible. Backflow Preventers should be located above grade or inside of a building rather than in a pit or below grade structure. As minimums, provide double check valve assemblies on all fire services or other water service connections that may have the potential for cross-connection. Provide reduced pressure zone backflow assemblies on all water service connections that may produce hazardous backflow conditions.
Metering: All domestic and reclaimed water service lines to each building shall be metered in accordance with NPS Staff Directive Plumbing Fixtures: All plumbing fixtures and fittings shall be low-flow, water conserving, conforming to the requirements stated in the Energy Policy Act.
Water Pressure: Pressure reducing valves shall be provided as necessary to limit water pressure in buildings to 80 per square inch gauge psig maximum. Booster pumps shall be provided as necessary to maintain a minimum of 25 psig at the furthest plumbing fixture at design flow rate conditions.
