A typical three-bedroom home, therefore, would have a projected daily flow of between 360 GPD and 600 GPD as the basic figure for calculating the overall size of the soil absorption system
(a soil loading rate being the other variable).
"The soil absorption system
, or leach field, is where the real treatment occurs," Joe says.
Individual site assessment to determine suitability is always necessary before designing and constructing a soil absorption system
of systems 713 Major system types Holding tanks, septic systems, cluster soil absorption system
Inspection frequency As requested Other services Pumping service, groundwater testing Property owner pays $117/year developed lots; $59/year undeveloped; $75 per pumpout Other support sources -- Overall cost per house [approximately equal to]$100 per year Auburn Lake Trails No.
Now You Own a Septic System" introduces the conventional septic-tank soil absorption system
-- In an aerated soil absorption system
, ammonium in septic-tank effluent is converted to nitrates.
To compensate for a high natural water table, the soil absorption system
was constructed by bringing in 1605 [m.sup.3] (2100 [yd.sup.3]) of fill, which was placed over existing pasture land.
Written for engineers and scientists involved in wastewater management, this guide describes water treatment methods and land planning approaches that use the least amount of mechanical elements when constructing ponds, wetlands, and soil absorption systems
. The authors discuss nitrogen removal in lagoons, on-site wastewater systems, sludge freezing, pond effluent upgrading, soil aquifer treatment systems, subsurface flow constructed wetlands, and vertical flow wetlands.

This trend seems to be holding steady or slightly increasing according to the Ohio Department of Health (ODH), which reported that between January 1 and June 30, 2007, 87% of systems installed were septic tanks discharging to soil absorption systems
Intermittent pressure dosing of effluent to soil absorption systems
has been investigated as a method for improving the aeration status and therefore promoting longevity of a system (McGauhney and Winneberger 1964; Bouma et al.
Meanwhile, in rural areas and suburbs all over the United States, where houses were scattered and constructed a few at a time, individual on-lot septic tanks and soil absorption systems
were pressed into use.
