How does a sewage treatment plant work?

A sewage treatment plant works by creating an artificial environment to speed up the natural process of breaking down pollutants in sewage, allowing the treated liquid to safely drain into the surrounding environment, and the sludge to be periodically tankered away.

The Environment Agency and SEPA now recommend sewage treatment plants over septic tanks and cesspools as they treat waste to a higher quality. Please contact us for more infomation.
