Waste Water Treatment

When it is not possible to connect to a mains sewer, septic tanks are usually the choice for domestic and commercial dirty water waste.

A sewage treatment plant can be an addition to and existing septic tank system or can come combined into more modern septic tanks.  The sewage treatment plant adds the ability to process the dirty water to a point where is deemed clean enough to discharge into the environment.

Where are sewage treatment plants used?

One of the many situations when sewage treatment plants really come into play is when site conditions don’t allow for a large enough soak away or when ground water level is high.

With a correctly specified and installed sewage treatment plant the output drainage water is clean enough to be discharged into a water course such as a stream or river (a permit may be required for this for more information see the Government  & Environment agency website for more details- Septic tanks and treatment plants: permits and general binding rules)

What is the difference between Cesspool, Septic Tank & Sewage Treatment Plant

·         A Septic Tank intercepts your drain water and separated the solid waste from the dirty water.  Using gravity the solid waste drops into the tank and the dirty was water is outputted via the septic tanks outlet to the soak away system to then deal with the dirty water.

·         A Sewage Treatment Plant, or sometimes referred to as a package treatment plant treats the water so that the water it outputs is clean enough to be soaked away into a stream or river.

·         A Cesspit or Cesspool usually found in older properties works inm the same way to a septic tank but is usually a brick built container for the sewage waste.
