What is an ETA septic system?
Evaporation-Transpiration (ET) Septic Systems, and Evapo-Transpiration Absorption Septic Systems (ETA) dispose of septic effluent from the septic tank by providing a surface area intended to allow the effluent to evaporate. Watch out: don’t pave-over nor drive over the septic fields or you may destroy the system.
What is a transpiration septic system?
Transpiration involves the removal of water by vegetation or how much water plants can soak using their roots. In most installations the septic tank is located upslope of the transpiration bed, so effluent will disperse through the transpiration trenches by gravity.
What is an ET bed?
An evapotranspiration (ET) bed treats wastewater by using evapotranspiration — the loss of water from the soil by evaporation and by transpiration from plants growing there. A liner is required if the surrounding soil is very permeable, such as in sandy gravel or karst limestone. …
How does above ground septic tank work?
Wastewater flows from the home to a septic tank, then via gravity to a pumping tank which pumps it to a sand mound located above ground level, where it is evenly distributed throughout the drain field.
What is an alternative to a leach field?
Sand Filter This is one example of an alternative septic system without a leach field, which makes it compatible with environmentally sensitive areas. In some cases, the treated water can pass directly from the sand filtration system to the soil without needing to flow through more piping to a leach field.
Is there an alternative to a septic tank?
The major alternatives to septic tanks include mound, aerobic septic, and cesspool systems, as well as sander filter, constructed wetlands, and drip irrigation. The mound system is most popular for soil that is too shallow over bedrock or for a water table which is too high.
