Idaho Administrative Code › Title IDAPA 58 - Environmental Quality, Department of › Rule 58.01.08 - IDAHO RULES FOR PUBLIC DRINKING WATER SYSTEMS › Section 58.01.08.541 - FACILITY AND DESIGN STANDARDS: PUMPING FACILITIES

Current through August 31, 2023
Pumping facilities shall be designed to maintain the sanitary
				quality of pumped water. (3-24-22)
01.
Pump Houses
. Unless otherwise approved by the Department based on
			 documentation provided by the design engineer, pump house components shall be
			 located above-grade. The following requirements apply to pump houses as defined
			 in Section 003 unless it can be shown that
			 some or all of these requirements are not needed to protect the combination of
			 system components in a given structure: (3-24-22)
a. Pump houses shall be readily accessible
			 for operation, maintenance, and repair at all times and under all weather
			 conditions unless permitted to be out of service for a period of
			 inaccessibility. (3-24-22)
b. Pump
			 houses shall be protected from flooding and shall be adequately drained. The
			 ground surface shall be graded so as to lead surface drainage away from the
			 pump house. Unless otherwise approved by the Department based on documentation
			 provided by the design engineer, the floor surface shall be at least six (6)
			 inches above the final ground surface and pump house components shall be
			 located at least six (6) inches above the floor surface. (3-24-22)
c. Pump houses shall be of durable
			 construction, fire and weather resistant, and with outward-opening doors. All
			 underground structures shall be waterproofed. (3-24-22)
d. Provisions shall be made for adequate
			 heating for the comfort of the operator and the safe and efficient operation of
			 the equipment. In pump houses not occupied by personnel, only enough heat need
			 be provided to prevent freezing of equipment or treatment processes.
			 (3-24-22)
e. Ventilation shall
			 conform to existing local and/or state codes. Adequate ventilation shall be
			 provided for all pumping stations for operator comfort and dissipation of
			 excess heat and moisture from the equipment. In all cases, measures must be
			 taken to minimize corrosion of metallic and electrical components.
			 (3-24-22)
f. Pump houses shall be
			 provided with a locking door or access to prohibit unauthorized entrance and
			 shall be protected to prevent vandalism and entrance by animals. Plans and
			 specifications for pump houses must provide enough detail to enable the
			 reviewing engineer to determine that the facility is secure, safe, accessible,
			 and that it conforms to electrical and plumbing codes. (3-24-22)
g. Pump houses shall be kept clean and in
			 good repair and shall not be used to store toxic or hazardous materials other
			 than those materials required for treatment processes. (3-24-22)
h. A suitable outlet shall be provided for
			 drainage from pump glands without discharging onto the floor.
			 (3-24-22)
i. Floor drains shall not
			 be connected to sewers, storm drains, chlorination room drains, or any other
			 source of contamination unless otherwise approved by the Department based on
			 documentation provided by the design engineer. Gas chlorination room drains
			 shall not be connected to any other drainage system and should terminate in a
			 properly located below ground sump. Sumps for pump house floor drains shall not
			 be closer than thirty (30) feet from any well. (3-24-22)
j. Adequate space shall be provided for the
			 installation of potential additional units and for the safe and efficient
			 servicing of all equipment. (3-24-22)
k. Suction basins shall be watertight, have
			 floors sloped to permit removal of water and settled solids, be covered or
			 otherwise protected against contamination, and have two (2) pumping
			 compartments or other means to allow the suction basin to be taken out of
			 service for inspection maintenance or repair. (3-24-22)
l. Pump houses shall be designed to allow
			 efficient equipment servicing. Crain-ways, hoist beams, eyebolts, or other
			 adequate facilities for servicing or removal of pumps, motors or other heavy
			 equipment shall be provided. Openings in floors, roofs or wherever else shall
			 be provided as needed for removal of heavy or bulky equipment.
			 (3-24-22)
m. All remote controlled
			 stations shall be electrically operated and controlled and shall have signaling
			 apparatus of proven performance. Signaling apparatus shall report automatically
			 when the station is out of service. (3-24-22)
n. Any threaded hose bib installed in the
			 pump house must be equipped with an appropriate backflow prevention device.
