The multi-pipe system is basically a drain filed system which does not use gravel or rock to aid in the dispersion of waste water.
One advantage of the multi-pipe system is the lower profile and higher efficiency of these systems.
It also means that the installations are shallower than the normal installations which may result in greater water table separations.
The installation design facilitates the most even distribution of waste water and acts like a trickle filter.
The multi-pipe rockless system can be used for residential and commercial septic tank installations.
