What are septic tank drainage fields?
Septic tank drainage fields are an integral part of a septic system. Often incorrectly called soakaways, a drainage field is much more than just a soakaway. A drainage field is a specifically designed arrangement of perforated pipework, laid in trenches to allow the effluent to filter into the ground. They are designed to ensure aerobic contact between effluent and the subsoil. Drainage fields need to be designed to individual requirements taking into consideration ground conditions, flows, property boundaries and many more factors.
