					 equipment. Auxiliary power for chemical addition, treatment, and monitoring
					 equipment is not required if the treatment, chemical addition, control, and
					 monitoring equipment is not necessary to meet the primary drinking water
					 standards in ch. NR 809 or the continuous disinfection requirements of chs.
					 NR
					 810 and
					 811.
(1) POWER SOURCES. Standby power may be
				  provided by any of the following:
(a) A
				  dedicated on-site generator or engine. A dedicated on-site generator may be
				  located inside or outside the building. Dedicated on-site engine-generator sets
				  installed within the building shall be located in a separate room. Diesel fuel
				  tanks shall be provided with secondary containment and interstitial leakage
				  monitoring and the installation shall receive written approval from the
				  department of safety and professional services or its authorized agent under
				  ch. ATCP 93 prior to installation. All fuel lines shall be exposed above grade.
				  Water lines to water cooled units shall be provided with backflow prevention in
				  accordance with s.
				  SPS
				  382.41.
(b) A portable power source owned by the
				  municipality and dedicated to the water supply facility operation.
(c) A portable power source not owned by the
				  municipality but only if the water system owner obtains a written agreement
				  with the owner of any portable power source, including tractors or trailered
				  engine-generator sets, that requires the water system owner to have primary
				  access to the power source in an emergency and that allows the portable power
				  source to be brought to the water system as required for testing. The portable
				  power source shall be located in the community if practical.
Note:
The department recommends the use of
					 water system owned dedicated on-site or portable engine-generator sets in all
					 cases. It is recommended that the equipment necessary to convert natural gas
					 fueled engines to propane be maintained on site in case the natural gas supply
					 has to be shut off for any significant length of time. It is recommended that
					 exterior engine-generator set installations be installed within a locked
					 security fence.

Current through June 24, 2024
Figure No. 1 located in the Appendix shall be used for
					 determining minimum pump capacities for domestic service only, unless specific
					 information is submitted to the department for review and the department
					 approves the alternate pump capacities. When using Figure No. 1, the number of
					 homes may be reduced by one-third for apartment units, condominium units, and
					 manufactured or mobile homes. As an alternative, for apartment units,
					 condominium units, and manufactured or mobile homes, the minimum pump capacity
					 may be reduced to 1 gallon per minute per living unit. The department may
					 require the water system owner to perform more detailed engineering studies to
					 determine pump capacities for multiple uses, including domestic, commercial,
					 and industrial usage and fire protection.

(1) PUMP BASES. If
				  a submersible pump is used, the top of the well casing shall be effectively
				  sealed against entrance of water under all conditions including vibration or
				  movement of conductors or cables. Requirements for the installation of pitless
				  units are provided in s.
				  NR
				  811.35. Submersible pump installations shall meet the

				  extended to terminate through the top of the well casing.
(b)
Well seals.
Well seals
				  shall consist of a sanitary surface plate bolted down with a gasketed or
				  machined seal to a flange welded to the well casing or alternatively, a
				  department approved well seal with one-piece top plate. All openings in the
				  well seal shall be sealed watertight with grommets or compression fittings to
				  prevent the entrance of contaminants.
(c)
Protective collars and pump
				  bases.

				  shall terminate at least 12 inches above the floor and be surrounded by a pump
				  base or a minimum 1.5-inch thick concrete collar. Either the pump base or the
				  concrete collar shall be installed to a height at least 6 inches above the
				  floor.
2. If a pump base is
				  installed, any other outer well casing shall be terminated a minimum of 4
				  inches above the finished floor and incorporated into the pump base.

(1) WELL VENT. Each well shall be vented to
				  the atmosphere in accordance with the following requirements:
(a) For wells without pitless units, a metal
				  vent pipe shall be installed that terminates in a 24-mesh corrosion resistant
				  screened "U" bend or mushroom cap at least 24 inches above the floor. The vent
				  pipe diameter shall be a minimum of 2 inches for well casings 10 inches in
				  diameter and larger. The department may, on a case-by-case basis, allow smaller
				  diameter well vents on existing installations if water drawdown has not
				  compromised the sanitary seal or require larger diameter well vents for wells
				  with significant water level drawdown. Vent piping shall be welded watertight
				  to the side of the well casing a minimum of 4 inches above the floor and may
				  extend through a concrete pump base or collar where one is present.
				  Alternatively, vent piping may project through a well seal or pump discharge
				  head if the well seal or discharge head is watertight and will facilitate the
				  installation of the vent pipe.
(b)
				  For wells with pitless units, a metal vent pipe shall be installed which
				  terminates in a 24-mesh corrosion resistant screened "U" bend or mushroom cap
				  at least 24 inches above the floor. The pitless unit vent area shall be equal
				  to or greater than the area provided by a 2-inch diameter vent pipe for pitless
				  units 10 inches in diameter or larger. Vent piping shall extend above or be
				  incorporated into the top of the pitless unit or be welded watertight to the
				  side of the pitless unit a minimum of 4 inches above the floor and may extend
				  through a concrete pump base or collar where one is present.
Note:
It is recommended that vent
					 installations for pitless units be factory installed to prevent damage to the
					 integrity of factory units and paint systems.
(c) If the well is flowing, the vent shall
				  terminate above the artesian water level or a suitable automatic valve shall be
				  provided.
