Disposal Field (Leach Line)
In addition to installing septic tanks, Alliance Septic Service can install new leach lines as well. There are several forms of leach lines from horizontal gravel, Bio Diffuser Chambers (Infiltrators), and vertical drilled leach wells. Depending on the type of ground, which varies greatly from one area to the next, Alliance Septic Service can design a leach system that will work for you.
Gravel leach lines are a time proven method of disposing of effluent (water that exits a septic tank) and can be installed in most areas and soil conditions. Gravel Leach lines are a single excavated trench or multiple connected by a distribution box for even flow. When the trench is complete and level from one end to the other, gravel fills up the portion of the trench designed for the individual job. At this point a perforated pipe is installed along the top of the level gravel fill to disperse effluent throughout the entire area. This is also similar to the vertical drilled leach well system except for all of the components are installed in a vertical hole in the ground then connected to the septic tank.
Infiltrator chambers are plastic half domed structures placed together in a trench that is leveled from end to end, then hooked to the septic tank. Multiple lines can be combined with a distribution box like the gravel leach lines. They are a versatile solution if the area where they are being installed has adequate space, as the Infiltrator style of leach lines require more horizontal length combined compared to gravel leach lines. Usually Infiltrator chambers are a more cost effective leach line solution due to the ease of installation and less materials overall being used.
