The 4800 Litre Cesspool Tank from GRAF sits in the middle of the Carat range. It is a good fit where usage is steady but light, such as a farm office, a stable yard toilet, a fishing lake facility or a seasonal café with its own washroom.
Made from tough, lightweight polyethylene, the 4800 litre cesspool tank is far easier to handle and install than concrete or steel. 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.

- 4,800 litre capacity (approx. 1,056 gallons)
- Holds raw sewage and effluent with no discharge to ground

- 15 year manufacturer warranty and 50 year design life
How Often Does a 4800 Litre Cesspool Need Emptying?
If around 100 litres a day enters the tank, the 4800 litre capacity works out at close to seven weeks between emptying. Where two or more toilets share the tank, the extra volume gives a useful safety margin.
For a permanent home, Building Regulations Approved Document H2 asks for a cesspool of at least 18,000 litres for two people. Smaller tanks like this one suit low-use, seasonal or temporary sites. Check with your local Building Control before you order one for a house.
