Section 445A.6711 - Distribution system: Pressure
Universal Citation: NV Admin Code 445A.6711
Current through September 16, 2024
1. A distribution system must be designed to maintain:
(a) A
minimum pressure of 20 psi at ground level for all service connections during
all conditions of fire flow experienced during maximum day demand.
(b) A normal working pressure of not less
than 40 psi during maximum day demand.
(c) A minimum pressure of 30 psi during peak
hour demand.
2. The zones of pressure of a distribution system must be designed in such a manner that the static pressure at the lowest ground elevation of the zone does not exceed 100 psi. If a zone of pressure may potentially exceed that pressure, the head in the zone must be controlled by the installation of a pressure regulator downstream from the service connection for each user of water in the zone.
