Commercial Sewage Treatment Plants

While most UK wastewater is handled by municipal treatment works, rural areas without mains drainage rely on landowners to arrange alternative disposal methods.

Cesspits

A Cesspit is an underground chamber used for the storage of sewage. The appearance of a cesspit is similar to that of a ‘hand dug’ water well.

How Our Commercial Sewage Treatment Plants Work

Commercial sewage treatment plants are engineered to provide comprehensive wastewater treatment. They typically include:

Primary Settlement: Initial phase where solids are separated from the liquid waste.
Biological Treatment: Microorganisms break down organic matter, reducing Biological Oxygen Demand (BOD), Suspended Solids (SS), and ammonia (NH4).
Final Settlement: Further clarification of the treated water, making it safe for discharge.

For additional protection, some systems have optional tertiary treatment procedures that can be installed to enhance the quality of the treated effluent. These filters provide extra filtration, ensuring compliance with the Environment Agency’s standards.
