Current through Register Vol. 50, No. 6, June 20, 2024
A. The
				sewer main and sewer laterals shall be installed in a separate trench not less
				than 5 feet (1524 mm) from the park water service or distribution system (see
				§613. C of this code).
B.
				The minimum size of pipe in any travel trailer park drainage system shall be 4
				inches.
C. Each travel trailer
				shall be considered as 6 fixture units in determining discharge requirements in
				the design of park drainage and sewage disposal systems.
D. Minimum
grade
(S) for sewers shall be so
				designed that the flow will have a mean velocity of 2 fps (0.6096 m/s) when the
				pipe is flowing half full.
E. The
				discharge of a park drainage system shall be connected to a community sewerage
				system. Where a community sewerage system is not available, an approved
				commercial treatment facility or individual sewerage system shall be installed
				in accord with the requirements of LAC 51:XIII (Sewage Disposal).
F. Manholes and/or cleanouts shall be
				provided and constructed as required in Chapter 7 of this code. Manholes and/or
				cleanouts shall be accessible and brought to
				grade(G).
G.
				When in a travel trailer park (i.e., other than a single travel trailer on its
				own lot), the sewer main shall be provided with a minimum 4-inch vent, not more
				than 5 feet (1524 mm) downstream from its upper trap. Long mains shall be
				provided with additional relief vents at intervals of not more than 200 feet
				(61 m) thereafter. These relief vents shall be a minimum of 4 inches and shall
				be securely supported and extended a minimum of 10 feet (3048 mm) above
				grade(G).
H.
				Branch lines or sewer laterals to individual travel trailers shall be not less
				than 4-inch diameter.
I. Sewer
				inlets shall be 4-inch diameter and extend above
				grade(G) 3 to 6 inches (76 to 152 mm). Each inlet shall
				be provided with a gas-tight seal when connected to a trailer and have a
				gas-tight seal plug for use when not in service.
J. Each trailer site shall be provided with a
				trailer trap. Sewer laterals over 30 ft (9144 mm) from the main park drainage
				sewer shall be provided with an individual vent and shall also be provided with
				a 4-inch cleanout brought to grade(G). When an
				individual vent for the sewer lateral/trailer trap is required, it shall be
				3-inch minimum (upstream of the clean out fitting) and shall extend not less
				than 10 inches above the roof of the travel trailer.
K. To provide the shortest possible drain
				connection between the travel trailer outlet and sewer inlet, all sewer inlets
				should terminate with reference to the site location of the travel
				trailer.
L. Drain connections shall
				slope continuously downward and form no traps. All pipe joints and connections
				shall be installed and maintained gastight and watertight.
M. No sewage, waste water, or any other
				effluent shall be allowed to be deposited on the surface of the
				ground.
N. Testing the Park
				Drainage System. Upon completion and before covering, the park drainage system
				shall be subjected to a static water test performed in accordance with §319. A of this code.
