Domestic water and wastewater treatment products

Structurally sound units

A cesspool is a covered, watertight tank used for storing sewage. It has no outlet and relies on road transport for the removal of raw sewage. No treatment is involved.

Guidance notes

• For domestic applications cesspools should have a capacity below the level of the invert of at least 18,000ltrs for two users, and should be increased by 6800ltrs for each additional user. Cesspools for commercial premises have no such restrictions
• Installation of a high level alarm is recommended to indicate when it is nearly full
• Whoever empties your cesspool (or septic/PSTP) should be a registrered Waste Carrier and hold a current discharge licence from the local water authority
• Use of cesspool is not permitted in Scotland
