What is a Septic Tank?
A septic tank is a self-contained wastewater treatment system that is located underground. Septic tanks effectively and efficiently treat and dispose of household wastewater on site. In rural areas where site sizes are larger and houses can be spaced quite widely apart, septic tanks can prove a much more economical solution than central sewer systems.
Carlow Concrete Tanks is one of the leading suppliers of domestic septic tanks in Ireland. Our 1000 gallon (4500 litres) septic tanks weights 4.5 tonnes and has a working capacity for up to 8 persons with 300mm risers available if required to bring access opening to ground level. Our Septic Tank system incorporates a 3-stage tank with three separate chambers of 330-gallon capacity and a percolation field.
Sewage enters our septic tank system through a ʻT-pieceʼ. This helps to avoid excessive turbulence in the primary chamber and reduces the speed of the flow rate. By discharging at mid depth in the tank, the scum at the surface is not broken. Therefore the system presents the ideal conditions for the first stage of the wastewater treatment.
The percolation area is essentially a drain field constructed of permeable materials and completely covered with soil and grass. The soil of the drain field needs to be loose enough to ‘percolate’ for the liquids to leech from the tank and be effectively dispersed.
In order to size the percolation area, a standard test is carried out (usually under supervision of a building professional or representative from a local authority in Ireland). Normally this is carried as part of a planning application. The EPA Design Manual further details the construction of a percolation area.
