111090.  Any owner or operator of a water-vending machine or other device from which any operator or customer dispenses vended water shall comply with the following standards of design, construction and sanitation and any additional standards adopted by regulation that the department determines are reasonably necessary to protect the public health. The water-vending machines or devices shall do all of the following:(a)  Comply with the construction and performance standards established by the department or by an independent authority approved by the department. (b)  Be designed and constructed to permit easy cleaning and maintenance of all exterior and interior surfaces. (c)  Have all parts and surfaces that come into contact with the water constructed of approved, corrosive-resistant and nonabsorbent material capable of withstanding repeated cleaning and sanitizing treatment. (d)  Have a recessed or guarded corrosion-resistant dispensing spout. (e)  Be designed so that all treatment of the vended water by distillation, ion exchange, filtration, ultraviolet light, reverse osmosis, mineral addition, or any other acceptable process is done in an effective manner. (f)  Have an effective system of handling drip, spillage, and overflow of water. (g)  Have a backflow prevention device approved by the department for all connections with the water supply. (h)  Dispense water disinfected by ultraviolet light or other method approved by the department prior to delivery into the customer’s container. (i)  Be equipped with monitoring devices designed to shutdown operation of the machine when the disinfection unit fails to function, or shall be monitored daily at startup and manually shutdown whenever the unit fails to function. (j)  Be equipped with a self-closing, tight-fitting door on the vending compartment, or enclosing the vending spout to protect the vending spout when the water-vending machine is not in use. As an alternative, water-vending machines or other water-dispensing devices may be enclosed in a room with tight-fitting walls, ceilings, and one of the following: a self-closing door, an effective air screen device, or an alternative effective device approved by the department. (k)  Comply with the American Water Works Association (AWWA) specifications for granular activated carbon if used in the treatment of potable water (AWWA B604-74).

(n)  Be located in an area that can be maintained in a clean condition and in a manner that avoids insect and rodent harborage. (o)  Be equipped with monitoring devices designed to shut down the labeled purified water delivery system if treatment of water by the machine does not result in a total dissolved solids content of less than 10 milligrams per liter in the purified water. Alternatively, machines shall be monitored daily at startup and manually shutdown whenever the total dissolved solids content exceeds 10 milligrams per liter in the purified water.
