What is the cost of installing a Cesspit (Cesspool)?

A cesspit, unlike a septic tank, is a single-stage unit that holds wastewater until it is full and needs to be emptied. If you’re researching the cost of installing a cesspool, there are a few factors to consider.

Size of the Tank

The size of your cesspit will inevitably affect the cost. A larger number of people living within the property will require a larger tank. However, a larger property doesn’t necessarily mean a larger tank is needed. A small-sized cesspool can cost upwards of £1500

Labour and Materials

The materials your system is made from will also affect the cost. Investing in a high-quality unit that will give you longevity is recommended. Cutting corners may result in frequent repairs and replacement costs.


Various companies offer installation services, but it’s recommended that you discuss installation with your local drainage company. They have the best knowledge of what to avoid and the best course of action.

Overall Cost

The cost of installing a cesspool will vary depending on the choices made. On average, the whole project should cost between £5000 – £15000.
