An important element of land development projects is wastewater disposal. For projects in areas without public sanitary sewer systems, a subsurface sewage disposal system typically will be required.
The Regulations to Govern Subsurface Sewage Disposal Systems can be found on the Tennessee Department of Environment & Conservation (TDEC) website, here: http://www.tn.gov/environment/water/septic-disposal_regulations.shtml
There is a misconception that the only option for a subsurface sewage disposal system is a standard septic tank with a conventional disposal (drain) field). But the Tennessee SDS regulations also include sewage disposal alternatives such as advanced treatment systems, low pressure pipe systems, and subsurface drip disposal (SDD) systems, to name a few. In many instances these alternative systems provide options to increase development density.
