A septic tank is designed to hold a body of still water in which anaerobic bacteria break down sewage. This forms three layers within the tank as follows;
As sewerage passes through the tank the solid waste floats to the surface where the bacteria act. To maintain optimum bacterial action it is important that this surface layer is not fouled with oils and fats and the system does not become flooded through poor drainage.
The Do’s and Don’ts:
DO – use biodegradable soaps to enable the quick breakdown of wastes and to avoid foaming
DO – clean your tank regularly – every 2-5 years.
DO – clean the filter every 6-12 months if your tank has one
DO – conserve water. E.g. only wash full loads of washing etc.
DO – contact us if you have any questions or enquiries. 0800 11 44 90
DO NOT – use excessive amounts of hard detergents or disinfectants, these kill the bacteria.
DO NOT – allow newspaper to enter the septic tank. The ink kills useful bacteria, and is also highly likely to block the pipework.
DO NOT – overload the tank with food scrapes, fat, cooking oil, sanitary pads, disposable nappies, etc.
DO NOT – grow deep rooting trees or shrubs on or around the septic tank and effluent trench
DO NOT – allow storm water to enter the septic tank or effluent trench
