All sewer lines shall be located in trenches of sufficient depth to be free of breakage from traffic or other movements and shall be separated from the park water supply system by a safe distance as approved by the Plumbing Inspector. Sewers shall be at a grade which will insure a velocity of two feet per second when flowing full. All sewer lines shall be constructed of materials approved by the Building Official, shall be adequately vented, and shall have watertight joints.
(C) Individual sewer connections.
(1) Each mobile home stand shall be provided with at least a four-inch diameter sewer riser pipe. The sewer riser pipe shall be so located on each stand that the sewer connection to the mobile home drain outlet will approximate a vertical position.

The sewer connection shall consist of one pipeline only without any branch fitting. All joints shall be watertight.
(3) All materials used for sewer connections shall be semi-rigid, corrosion resistant, nonabsorbent and durable. The inner surface shall be smooth.
(4) Provision shall be made for plugging the sewer riser pipe when a mobile home does not occupy the lot. Surface drainage shall be diverted away from the riser. The rim of the riser pipe shall extend at least two inches above ground elevation.
(D) Sewage treatment and/or discharge.
