Current through June 24, 2024
(1) GENERAL. An adequate supply of potable
				  water shall be supplied under pressure for milkhouse and milking operations.
				  Water used for milkhouse and milking operations, including water used to cool
				  milk in a plate or tubular cooler, shall be potable. Potable water shall comply
				  with the microbiological drinking water standards set forth in s.
				  NR
				  809.30.
Note:
A properly designed and installed water
					 supply tank that utilizes static head pressure to provide potable running water
					 to the milkhouse is minimally adequate to comply with this
					 paragraph.
(2) BACKFLOW
				  PROTECTION; CROSS-CONNECTIONS. A potable water supply system on a dairy farm
				  shall be designed, constructed, installed, and maintained to prevent
				  contamination of the potable water supply through backflow, backsiphonage,
				  cross-connections, or any other connection to the potable water supply system.
				  An air gap adequate to prevent the back-siphonage or backflow of any liquids
				  shall be maintained between every potable water outlet and the flood rim of the
				  fixture that it supplies, and between the potable water outlet and every other
				  source of potential contamination, unless alternative protection is approved
				  under s.
				  SPS
				  382.41.
(3) WELL CONSTRUCTION. Wells used to supply
				  water for milkhouse and milking operations on dairy farms shall comply with ch.
				  NR 810, 811, or 812 in the case of a community water system.
(4) WATER TRANSPORTED TO DAIRY FARM. A person
				  transporting water in containers or tanks to a dairy farm for milkhouse or
				  milking operations shall seal the containers or tanks to prevent contamination.
				  The containers and tanks shall be thoroughly cleaned and sanitized before being
				  filled with potable water for use at the dairy farm. A sanitarily designed,
				  cleaned, and sanitized pump, hose, and fittings shall be used to transfer water
				  from transport containers and tanks to previously cleaned and sanitized storage
				  tanks at the dairy farm so that the water is not contaminated during transfer
				  or by the storage tanks.
(5) WATER
				  QUALITY TESTING BY DAIRY PLANT. A dairy plant operator, including a milk
				  contractor that submits a milk producer license application on behalf of a milk
				  producer and thereby certifies that the milk producer's dairy farm and milking
				  operations comply with applicable requirements under this chapter, shall do all
				  of the following for each milk producer from whom the dairy plant operator
				  procures milk:
(a) Sample the milk producer's
				  water supply at least once every two years. If the water supply system has more
				  than one well, water from each well shall be sampled. The water sample from
				  each well shall be taken from water before it has flowed into a pressure tank
				  or any water treatment equipment.
(b) Sample the milk producer's water supply
				  whenever the milk producer installs, alters, or repairs the water supply
				  system.
(c) Sample any transported
				  water supply used by the milk producer at the point of use, at or before first
				  use and monthly thereafter.
(d)
				  Have each water sample under this subsection analyzed at a laboratory that is
				  certified under ch. ATCP 77 to perform water quality analyses. The laboratory
				  shall analyze the water samples for compliance with the microbiological
				  drinking water standards set forth in s.
				  NR
				  809.30. The dairy plant operator shall submit each
				  water quality analysis result to the division within 30 days after the dairy
				  plant receives the water quality analysis result. If the analysis of any water
				  sample indicates that the water supply of a dairy farm may be unsafe, the dairy
				  plant operator, within 3 business days of the water quality analysis result
				  being reported to the dairy plant operator, shall report the analysis result to
				  the division and resample the water supply and have it analyzed.
