The 52000 Litre Cesspool Tank from GRAF meets the Building Regulations size for a household of up to seven people. It is also a good fit for a small group of cottages or holiday lets sharing one tank.
Made from tough polyethylene, the 52000 litre cesspool tank is much lighter than concrete or steel, which makes it quicker to install. It is watertight and holds all incoming effluent and raw sewage with no outlet. A licensed waste carrier empties it when it gets close to full.

Sizing a 52000 Litre Cesspool
Building Regulations Approved Document H2 asks for at least 18,000 litres for two people, plus 6,800 litres for each extra person. On that basis the 52000 litre cesspool suits up to 7 people in a permanent home.
At around 150 litres per person per day, a full household of 7 would fill the tank in roughly 7 weeks, so plan your collections around that.
