(3) Sewer inlet connections at individual recreational vehicle unit sites:
(i) When provided, the sewer connections for individual recreational vehicle sites shall be located so as to minimize damage by the parking of recreational vehicles or automobiles.
(ii) The connection shall consist of an inlet extending vertically to grade. The minimum diameter of the sewer inlet shall be four (4) inches and shall be provided with a four-inch (4) inlet or a minimum three-inch (3) fitting.
(iii) The sewer inlet pipe shall be firmly imbedded in the ground and be protected against damage from heaving or shifting and the entrance of surface water. It shall be provided with a tight-fitting plug or cap to be used when the site is vacant.
(iv) The sewer inlet pipe shall not be required to be individually vented, regardless of the use of the traps at each inlet.
(v) A drain connector shall be sealed and fitted to the camping unit inlet connector.

(4) Recreational vehicle sanitary disposal stations:
(i) One recreational vehicle sanitary disposal station shall be provided for each one hundred (100) recreational vehicle sites, or parts thereof, that are not equipped with individual sewer connections.
(ii) Each station, where provided, shall be convenient to access from the service driveway and shall provide easy ingress and egress for recreational vehicles.
(iii) Unless other approved means are used, each station shall have a concrete slab with a center drain inlet located so as to be on the driveway (left) side of the recreational vehicle.
(iv) The slab shall be not less than three (3) feet by three (3) feet, at least three and one-half (3½) inches thick, and properly reinforced, the surface of which is trowelled to a smooth finish and sloped from each side inward to a sewer inlet.
(v) The sewer inlet shall consist of a four-inch (4), self-closing, foot-operated hatch of approved material with a tight-fitting cover. The hatch body shall be set in the concrete of the slab with the lip of the opening flush with its surface to facilitate the cleansing of the slab with water. The hatch shall be properly connected to a sewer inlet that shall discharge to an approved sanitary sewage disposal facility constructed in accordance with ANSI A119.4 section 4-8.1.

(5) Holding tank flushing facilities: Where holding tank flushing facilities are provided by the operator, the following standards shall apply:
(i) Holding tank flushing facilities shall consist of piped supply of water under pressure, terminating in a valved outlet located and installed to minimize damage by automobiles or recreational vehicles. The flushing device shall consist of a properly supported riser terminating at least two (2) feet above the ground surface with a three-quarter (¾) inch valved outlet to which is attached a flexible hose.
(ii) The water supply to the flushing device shall be protected from backflow by means of a listed vacuum breaker located downstream from the last shutoff valve.
(iii) Adjacent to the flushing arrangement there shall be posted a sign of durable material, not less than two (2) feet by two (2) feet in size, and inscribed in clearly legible letters with the following: “DANGER — NOT TO BE USED FOR DRINKING OR DOMESTIC PURPOSES” or other similar warning.
(iv) There shall not be any cross-connection between the holding tank flushing facilities and the potable water system. If the flushing facilities do not have a separate water source entirely, such facilities shall be separated from any potable system by an air gap or a backflow device.
(6) Sanitary facilities:
(i) Toilets shall be provided at one or more locations in every recreational vehicle park or campground, except at primitive and semi-primitive campgrounds.
(ii) In recreational vehicle parks and semi-developed and developed campgrounds, a minimum of one toilet shall be provided for each sex up to the first twenty-five (25) dependent sites. For each additional twenty-five (25) dependent sites, not provided with sewer connections, an additional toilet for each sex shall be provided. No public toilets are required if all sites serve only self-contained recreational vehicles.
(iii) Chemical and recirculating toilets shall be of an approved type.
(iv) Where provided, porta-johns shall be an approved type.
(v) Toilet facilities shall have convenient access and shall be located within a five-hundred-foot (500) radius from any camping units not provided with individual sewer connections.

Listed exhaust fan(s), vented to the exterior, the rating of which in cubic foot per minute is at least twenty-five percent of the total volume of the toilet room(s) served, shall be considered as meeting the requirements of this subsection.
