Drain Interceptors


Many businesses use drain interceptors. They are also known as a drain interceptor trap or a separator. The purpose of a drain interceptor is to separate oil or other contaminants from liquid wastewater. The interceptors have to be cleaned and contaminants disposed of legally and ethically. That is where our Tardis services come in!

Where are drain interceptors found?


Drain Interceptors reside in many places underground. The most common locations are:


  • Industrial Estates
  • Pubs
  • Schools
  • Car parks
  • Supermarket car parks
  • Hospitals
  • Lorry Parks
Interceptors stop effluent and run-off from vehicles or other cleaning activities. However, these run-offs if uncaught, can damage the environment and pollute rivers or streams.


Take the scenario, for example, that a car is leaking oil in a car park and it starts to rain. The drains begin doing their jobs by draining the water, but it’s up to the interceptor to successfully trap the oil in the water and store it separately. The oil and water will run together into the drain; however, when passing through the drain, it will become separated as the interceptor traps the oil. The water runs through separately.

Interceptors help protect the environment ultimately and the business’s reputation. There have been cases where contaminants have affected a local water stream and harm wildlife.

Dirty water or run-off from vehicle washing/cleaning activity is called trade effluent. Whether you’re cleaning one vehicle or responsible for a large lorry fleet, you must arrange for collection and disposal of effluent. It’s illegal to discharge trade effluent to the environment or into drains without permission.
