Septic tanks work slightly differently to sewage treatment plants. A septic tank only partially treats sewage by using an anaerobic process and as a consequence it is illegal under General Binding Rules to discharge effluent from a septic tank into a water course or surface water. Effluent discharges from a septic tank can only legally discharge into a functioning soakaway/ sub-surface irrigation system. The porosity of the soil will determine whether a soakaway will work and therefore whether a septic tank is even a suitable long term solution. If you’re not sure if it is suitable for your home or premises, then contact us.
