8.2 The sewer lines shall be constructed of approved materials with adequate vents, water-tight joints,

and sufficient cleanouts. All sewer lines shall have a minimum diameter of six inches except that a sewer lateral which serves no more than 25 individual sewer connections for individual camping vehicle lots or no more than five toilet connections may be four inches in diameter.

8.3 Sewers shall be installed at a grade of at least one-eighth inch per foot to insure a velocity of two feet per second when flowing full. Horizontal drainage lines connecting with other horizontal drainage lines shall enter through 45 degree "y" branches or other combinations of equivalent sweep.
8.4 Cleanouts or manholes shall be provided at the upper end of each main sewer line, at intersections of two or more sewer lines, changes in grade or alignment of more than 45° and at intervals of not more than 400 feet.
8.5 Individual sewer connections shall meet the following requirements:
a. A four inch inside diameter sewer lateral and riser pipe with the surrounding ground graded to drain from the rim of the riser pipe. The sewer lateral shall be properly trapped and vented if camping vehicles without individually trapped and vented plumbing fixtures are accommodated.

The sewer service connection shall be installed and maintained with a grade not less than one-quarter inch per foot.
8.8 When the campsite is not occupied, the sewer riser pipe shall be adequately covered.
8.9 A flushing sink or other means of disposal shall be provided for disposal of liquid wastes from dependent camping vehicles, unless a sanitary waste station is provided and is conveniently located. The flushing sink shall be easily accessible and located at a distance of not more than 300 feet from any campsite. The sinks shall not be located in a room containing toilet, lavatory or bathing facilities, and toilets shall not be used for disposal of such liquid wastes.

a. Easy ingress and egress from a service road for camping vehicles and located not less than 50 feet from a campsite.
b. Connection to the sewer system by a trapped four inch sewer riser pipe and vented not more than 10 feet down stream from the trap by a four inch vent adequately supported, and extending at least eight feet above the ground surface.
c. The sewage inlet surrounded by a curbed concrete apron or trough of at least three feet by three feet, sloped to the inlet, and provided with a suitable hinged cover milled to fit tight.
d. A means for flushing the immediate area, and camping vehicle holding tank shall be provided at each sanitary waste station. It shall consist of a properly supported water riser pipe terminating two feet above the ground with a 3/4 inch valved outlet and attached hose. The water outlet shall be protected against backsiphonage and backflow by an approved vacuum breaker installation located downstream from the shut-off valve.
