The following standards shall apply to recreational vehicle parks and campgrounds:

(1) Potable water supply and distribution:

(i)  The supply or supplies of potable water shall comply with the applicable potable water standards of the authority having jurisdiction or, in the absence thereof, shall meet the intent of the Safe Drinking Water Act of 1974 (public law 93-523 as amended (1986)) [42 U.S.C. § 300f et seq.].

(ii)  Where the recreational vehicle park or campground has its own water supply system, the components of the system shall be approved by the authority having jurisdiction. Further, there shall be a source protection buffer area of at least two hundred (200) feet surrounding each such supply.

(iii)  Potable water systems, if provided for filling recreational vehicle potable water tanks, shall be located at least fifty (50) feet from any waste disposal station. When such a system is provided, a sign of durable material, not less than two (2) by two (2) feet in area, shall be posted adjacent to the potable water outlet. Such sign shall be inscribed in clearly legible letters with the following: “POTABLE WATER NOT TO BE USED FOR FLUSHING WASTE TANKS,” or other similar warning. For the purpose of this subsection, a potable watering system shall mean a tap and not the source.

(iv)  The potable water system should be protected from back-flow by means of a listed vacuum breaker located downstream from each connection.

(2) Water supplies for fire protection:  Water supplies for fire protection purposes shall meet the requirements of the authority having jurisdiction.

(3) Prohibited connections:  The potable water supply shall not be connected to any nonpotable or unapproved water supply.

(4) Potable water connections at individual camping unit sites:  All wells, springs, and similar sources of water intended for potable purposes shall be properly constructed, located, and protected to exclude surface contamination and to minimize the potential of contamination from sanitary hazards.
