  (a) safe;

  (b) durable, corrosion resistant, and nonabsorbent;

  (c) finished to have a smooth, easily cleanable surface; and

  (d) designed and intended only for use with potable water.

  (6) A fitting with "V" type threads on an onboard water tank inlet or outlet shall be allowed only when a hose is permanently attached.

  (7) If provided, an onboard water tank vent shall terminate in a downward direction and shall be covered with:

  (a) 16 mesh to 25.4 mm (16 mesh to 1 inch) screen or equivalent when the vent is in a protected area; or

  (b) a protective filter when the vent is in an area that is not protected from windblown dirt and debris.

  (b) An operator shall only use a hose designed and intended to convey potable water when filling an onboard water tank as described in Subsection R392-102-7(1)

  (10) A food truck operator shall install and maintain a filter that does not pass oil or oil vapors in the air supply line between the compressor and potable water supply system when compressed air is used to pressurize the water tank system.

  (11)(a) A cap and keeper chain, closed cabinet, closed storage tube, or other protective cover or device approved by the local health officer shall be provided for a water inlet, outlet, and hose.

  (b) The protective cover or device shall be used whenever the water tank or hose inlet and outlet fitting is not in use.

  (12) A food truck's onboard water tank inlet shall be:

  (a) 19.1 mm (three-fourths inch) in inner diameter or less; and

  (b) provided with a hose connection of a size or type that will prevent its use for any other service.

  (13) The operator shall flush and sanitize any water tank, pump, and hoses before placing into service after initial purchase, construction, repair, modification, and periods of nonuse of 30 days or more, and as often as necessary to maintain the equipment in clean and sanitary condition.

  (14) A food truck operator shall operate a water tank, pump, and hoses so that backflow and other contamination of the water supply are prevented.

  (15)(a) A wastewater holding tank in a food truck shall be:

  (i) sized 15 percent larger in capacity than the water supply tank; and

  (ii) sloped to a drain that is 25 mm (1 inch) in inner diameter or greater, equipped with a shut-off valve.

  (b) Subsection R392-102-7(15(a)(i) does not apply to a potable water tank that is used only for beverage service on a food truck and is not connected to a wastewater holding tank.

  (16) Wastewater shall be conveyed to the point of disposal through an approved sanitary sewage system or other system, including use of wastewater transport vehicles, waste retention tanks, pumps, pipes, hoses, and connections that are constructed, maintained, and operated according to:

  (b) A food truck operator shall thoroughly flush and drain a tank for liquid waste retention in a sanitary manner during the servicing operation.

  (18) Wastewater or liquid waste conveyance lines that are not shielded to intercept drips shall be installed or located under food and food contact surfaces.

  (19) The operator shall store potable water pipes, hoses, and tubes separately from wastewater pipes, hoses, and tubes in a manner that prevents cross contamination.
