The first step in any septic installation is to perform a site survey and do a percolation soil test on the area where the powts is going to be installed. Effluent flows into this large open area underneath the yard. Infiltrator quick4 plus series chambers are high density polyethylene arches that interlock to form a continuous drainage area with a much greater storage surge volume than pipe in gravel leach fields.

With no gravel inside chambers have ample air to help keep the leach field soil aerobic and healthy. The size necessary for your drain field will depend on a few factors. The entire bottom of a chamber is open. Vertical pipes are placed usually at the end of each drainfield trench or section or at critical or suspect areas near the drainfield to permit monitoring of liquid levels in the drainfield trenches.

The drain field also called the leach field performs more than half the job in a conventional residential septic system. An improperly designed drain field will do nothing but cause huge problems with the entire system. The system then can be designed based on the findings of the survey and results of the soil test.
