The 10000 Litre Cesspool Tank from GRAF is a Carat XL holding tank for medium-use sites. It works well for sports clubs, small campsites, shared workshop units and other places with regular but not heavy toilet use.
Made from tough polyethylene, the 10000 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 10000 Litre Cesspool
For a permanent home, Building Regulations Approved Document H2 asks for a cesspool of at least 18,000 litres for two people. This size suits low-use, seasonal or temporary sites rather than a house, so check with your local Building Control if you are unsure.
At around 100 litres a day going in, this tank holds roughly 14 weeks of wastewater before it needs emptying.
