If your home or premises is connected to a domestic waste water treatment system (DWWTS), such as a septic tank, then you should have the sewage sludge removed at appropriate intervals.
This will depend on the size your system and the number of people in the house, but is typically between one and two years (unless otherwise recommended by the manufacturer).
Your system should be emptied by an authorised contractor. As a homeowner, you should get a receipt from the authorised contractor each time your tank is emptied and you should keep the receipt for five years.
