New Conventional Gravity Septic Systems




New Conventional Gravity Septic Systems  

Only a few years ago all septic systems utilized gravity distribution to dispose of sewage effluent. Lately gravity designs are still very much in use and will always be around. This is especially true in deep loamy soils where pressure distribution within the drainfield offers no treatment advantage. The four examples in this section; Frost, Lesmore, West Repair, and Wiggy represent designs for average type conventional residential homesites including a repair for an older system.  

Many local health jurisdictions these days want to see a cross-section of the drainfield soil profile including any restrictive soil units. The drawings in this chapter include several soil conditions and soil depths which require a range of notes you would see on the septic plans or on presentation drawings for a health permit application. These standard specifications may include minimum and maximum trench depths and many other details. Septic system drawings are now part of any formal application for construction of a new house. The CAD (computer aided) drawing templates included here can be easily made specific to your location and its rules.  

If any parts of the Eco-nomic templates are made a part of say an application for a regulated septic system, confirm with a call to local health that the person submitting them has all the information needed to prepare a complete application and is properly qualified to do so.
