(1) Capacity and Minimum Distribution System Pressure. A pump used to provide minimum distribution system pressure shall:
(a) have
the capacity to meet the maximum demand of the specific portion of the
distribution system served; and
(b)
be capable of providing the minimum pressures required by Section
R309-105-9.
(2) Number of Pumps.
(a) A water supplier shall have at
least two pumps installed and in operation at a booster pump facility that
provides the only means available to meet the minimum distribution system
pressure requirements of Section R309-105-9 for the water distribution pipeline
served by the facility.
(b) A
booster pump facility that requires at least two pumps shall meet the maximum
demand of the water distribution pipeline served by the facility with the
largest pump out of service.
(3) Booster Pumps.
(a) A booster pump shall be equipped with an
automatic shutoff or low-pressure controller as recommended by the pump
manufacturer.
(b) A booster pump
withdrawing water from a distribution line shall maintain an intake pressure of
at least 20 psi when the pump is in normal operation.
(c) A booster pump withdrawing water directly
from a water storage tank shall be provided with net positive suction
head.
(4) Pump Motor. A pump motor shall:
(a) be sized to meet
operating conditions without overloading; and
(b) provide the maximum horsepower required
by the pump without the use of a service factor.
(5) Certification of Drinking Water Treatment Chemicals and System Components.
(a) Chemicals
added to drinking water at pump facilities shall be certified to meet NSF/ANSI
60.
(b) Products, components, and
materials used in pump facilities that may impart chemical contaminants or
impurities to drinking water shall be certified to meet NSF/ANSI 61.
(6) Suction Lift. When a pump provides suction lift:
(a) the maximum lift
shall be within the pump manufacturer's recommended limits; and
(b) tanks priming shall be provided for the
pump.
(7) Priming.
(a) When a pump requires priming, the priming
system shall:
(i) use water of at least the
same quality as the water being pumped; and
(ii) include a means to prevent back
siphoning.
(b) When an
air-operated ejector is used for vacuum priming, it shall draw clean air
through a screened intake:
(i) at least ten
feet above the ground; and
(ii) at
least ten feet away from a point of contamination.
(8) Water Seal.
(a) Water used as a seal for a pump shall be
of at least the same quality of the water being pumped.
(b) A water line supplying drinking water
used as a seal for a pump that pumps non-potable water shall be protected from
backflow.
(9) Individual Home Booster Pumps. Individual home booster pumps shall not be allowed for any individual service from the public water supply main. Exceptions may be granted by the Director if it can be shown that the granting of an exception will not jeopardize public health.
