Crossover Systems
(use on slopes)
- It is important to have sufficient drop in the line from the tank to the first drainage trench to prevent the back up of effluent into the tank before the effluent can flow over the first crossover.
- Crossovers must be constructed, in undisturbed soil, of solid non-perforated pipe.
- The most impermeable soil available (i.e. - clay) must then be packed around these crossover pipes.
- Under no circumstances shall gravel be placed in the crossover trench.
- Crossovers should be constructed high enough to insure that sewage fills the entire trench to a depth of 12 inches before overflowing through the crossover to the next trench.
- A 4-inch observation pipe should be installed at the end of the drainage trench. The pipe would extend to the surface of the ground and be capped.
