HEALTH AND SAFETY CODE
SECTION 114205-114242



114205.  (a) Nonpermanent food facilities that handle nonprepackaged
food shall be equipped with potable water and wastewater tanks,
unless approved temporary water and wastewater connections are
provided.
   (b) Permanent food facilities shall be in compliance with Sections
114190 to 114201, inclusive.


114207.  Materials that are used in the construction of potable
water and wastewater tanks and appurtenances shall be safe, durable,
corrosion-resistant, nonabsorbent, and finished to have a smooth,
easily cleanable surface.


114209.  Potable water tanks and wastewater tanks shall be sloped to
an outlet that ensures complete drainage of the tank and designed
and constructed so as to be easily and completely drained.



114211.  (a) The water system shall be designed and constructed
using materials that enable water to be introduced without
contamination.
   (b) All tanks, line couplings, valves, and all other plumbing
shall be designed, installed, maintained, and constructed of
materials that will not contaminate the water supply, food, utensils,
or equipment.
   (c) All waste lines shall be connected to wastewater tanks with
watertight seals.
   (d) Any connection to a wastewater tank shall preclude the
possibility of contaminating any food, food-contact surface, or
utensil.



114213.  (a) Any potable water or wastewater tank mounted within a
mobile food facility or mobile support unit shall have an air vent
overflow provided in a manner that will prevent potential flooding of
the interior of the facility.
   (b) If provided, a water tank vent shall terminate in a downward
direction and shall be covered with 16 mesh per square inch screen or
equivalent when the vent is in a protected area or a protective
filter when the vent is in an area that is not protected from
windblown dirt and debris.



114215.  Hoses used in conjunction with nonpermanent food facilities
shall meet all of the following requirements:
   (a) A hose used for conveying potable water from a water tank
shall be:
   (1) Safe.
   (2) Durable, corrosion-resistant, and nonabsorbent.
   (3) Resistant to pitting, chipping, crazing, scratching, scoring,
distortion, and decomposition.
   (4) Finished with a smooth interior surface.
   (5) Protected from contamination at all times.
    (6) Clearly and durably identified as to its use if not
permanently attached.
   (b) Liquid waste lines shall not be the same color as hoses used
for potable water.
   (c) Hoses used on a mobile food facility or a mobile support unit
and potable water tank connectors shall have matching connecting
devices. Devices for external cleaning shall not be used for potable
water purposes on the mobile food facility. Hoses and faucets
equipped with quick connect and disconnect devices for these purposes
shall be deemed to meet the requirements of this subdivision.
Exterior hose-connection valves shall be attached to mobile food
facilities or mobile support units and shall be located above the
ground with an approved water connection.


114217.  (a) A potable water tank of sufficient capacity to furnish
an adequate quantity of potable water for food preparation,
warewashing, and handwashing purposes shall be provided for
nonpermanent food facilities.
   (b) At least five gallons of water shall be provided exclusively
for handwashing for each nonpermanent food facility. Any water need
for other purposes shall be in addition to the five gallons for
handwashing.
   (c) Except as specified in subdivision (d), at least 25 gallons of
water shall be provided for food preparation and warewashing.
   (d) At least 15 gallons of water shall be provided for
nonpermanent food facilities that conduct limited food preparation.
   (e) The water delivery system shall deliver at least one gallon
per minute to each sink basin.


114219.  A potable water tank shall be enclosed from the filling
inlet to the discharge outlet and emptied to ensure complete drainage
of the tank.


114221.  (a) Water tanks shall be designed with an access port for
inspection and cleaning. The access port shall be in the top of the
tank and flanged upward at least one-half inch and equipped with a
port cover assembly that is provided with a gasket and a device for
securing the cover in place and flanged to overlap the opening and
sloped to drain.
   (b) Notwithstanding subdivision (a), water tanks that are not
accessible for inspection may comply with this section by submitting
written operational procedures for the cleaning and sanitizing of the
potable water tank. The enforcement agency shall review and approve
the procedures prior to implementation and an approved copy shall be
kept on the mobile food facility during hours of operation.



114223.  A fitting with "V" type threads on a water tank inlet or
outlet shall be allowed only when a hose is permanently attached.



114225.  (a) Potable water tanks shall be installed in a manner that
will allow water to be filled with an easily accessible inlet.
   (b) A potable water tank's inlet and outlet shall be positioned so
that they are protected from contaminants such as waste discharge,
dust, oil, or grease.
   (c) Nonpermanent food facilities shall be provided with a
connection of a size and type that will prevent its use for any other
service and shall be constructed so that backflow and other
contamination of the water supply is prevented.



114227.  A filter that does not pass oil or oil vapors shall be
installed in the air supply line between the compressor and potable
water system when compressed air is used to pressurize the water tank
system.


114229.  If not in use, a potable water tank and hose inlet and
outlet fitting shall be protected using a cap and keeper chain, quick
disconnect, closed cabinet, closed storage tube, or other approved
protective cover or device.


114231.  A nonpermanent food facility's potable water tank inlet
shall be three-fourths inch in inner diameter or less and provided
with a hose connection of a size or type that will prevent its use
for any other service.


114233.  A water tank, pump, and hoses shall be flushed and
sanitized before being placed in service after construction, repair,
modification, and periods of nonuse.



114235.  A person shall operate a water tank, pump, and hoses so
that backflow and other contamination of the water supply are
prevented.


114238.  A water tank, pump, and hoses used for conveying potable
water shall not be used for any other purpose.

the preparation of a food or beverage is supplied, an additional
wastewater tank capacity equal to at least 15 percent of the water
supply shall be provided.
   (c) Additional wastewater tank capacity may be required where
wastewater production is likely to exceed tank capacity.
   (d) Where ice is utilized in the storage, display, or service of
