Septic Tanks come in all shapes and sizes and in varying states of repair. Septic tanks are used for the storage and/or treatment of foul waste from any property that is not connected to mains drainage. Regardless of type, age, function or location all septic tanks require a regular empty, known as a de-sludge, to keep them in operational condition. If your property uses a septic tank or the like it is your responsibility to know how your system works and to ensure it is serviced regularly.
Modern septic tanks, sewage treatment plants and cesspits are designed to treat a specified volume of water over a daily period; this is calculated on maximum persons that could live in the property [not necessarily living in the property at that time] and allowing for a set amount of water per person.
