Each facility shall be equipped with effective plumbing and sewage facilities and adequate accommodations including, but not limited to, the following:

  1. The water supply shall be sufficient for the operations intended and shall be derived from an approved source. Drinking water and water used for food processing operations shall meet bacteriological and chemical quality standards specified in 327 IAC 8-2. Running water at a suitable temperature and under pressure as needed shall be provided in all areas where required for the processing of food, for the cleaning of equipment, utensils, and food-packaging materials, or for employee sanitary facilities.

  2. If a food processing plant obtains water from a water system not subject to 327 IAC 8-2 for its operations the operator shall sample the water at least annually for bacterial analysis by a certified laboratory, maintain records of analysis of sample results for three (3) years, and provide such records to the department upon request.

  3. A plumbing system shall be of sufficient size and shall be designed, constructed, installed and maintained according to the applicable Indiana Plumbing Code, 675 IAC 16.1, to:

  1. Carry sufficient quantities of water to required locations throughout the facility.

  2. Properly convey sewage and liquid disposable waste from the facility.

  3. Avoid constituting a source of contamination to food, water supplies, equipment and utensils or creating an unsanitary condition.

  4. Provide sufficient floor drainage in all areas where floors are subject to flooding-type cleaning or where normal operations release or discharge water or other liquid waste on the floor.

  5. Prevent backflow or backsiphonage from, or cross-connection between, piping systems that discharge wastewater or sewage and piping systems that carry water for food or food manufacturing. This shall be accomplished by:

  1. installing a backflow or backsiphonage prevention device on a water supply system which meets the standards in 675 IAC 16.3 for construction, installation, maintenance, inspection and testing for that specific application and type of approved device.

  2. using an air gap, if necessary, between the water supply inlet and the flood level rim of the plumbing fixture, equipment, or nonfood equipment. It shall be at least twice the diameter of the water supply inlet and may not be less than one (1) inch. It shall be a minimum of two (2) pipe diameters of the pipe or six (6) inches, whichever is the lesser.

  1. Sewage disposal shall be conveyed into an approved sanitary sewerage system or other system, including the use of sewage transport vehicles, pumps, hoses and connections that are constructed, maintained and operated according to law.
