Interceptor Cleaning and Servicing

We offer competitively priced liquid waste collection services with experienced drivers and operatives utilising high-performance vacuum tankers equipped with jetting and wash down equipment.

Accumulation of silt and debris in the interceptors will prevent them from working efficiently and so they need to be regularly emptied and cleaned, otherwise a pollution incident will inevitably occur.

Whilst on site attending to your interceptors our vacuum tanker service can include cleaning out of gully pots, drainage channels, bunds, catchment pits and sumps.

Cutting/suds oils are polluting to water and must not be directed into the surface water systems. Our vacuum tankers will call to your premises and we will arrange for safe disposal.

What are Interceptors / Separators?

Water from vehicle parking areas, yards and forecourts should run to a surface water interceptor where oil and silt will be retained before the liquid, which should be clean and unpolluted, discharges to surface water drains and eventually to local water courses. You are legally responsible for making sure that the discharge does not pollute the receiving water course.

Only clean and unpolluted water should be directed to surface water interceptors, storm drains, watercourses or soakaways.

Effluent arising from vehicle wash operations containing detergents (including so-called bio-degradable), traffic film removers and other chemicals must be directed to the foul drainage system. So too must liquid waste arising from vehicle maintenance and workshops, canteens and laboratories.

If you have concerns relating to the correct discharge of effluent from your premises you should consider carrying out a drainage survey.

Detergents, oil and chemicals will pollute streams and rivers even if discharged through interceptors, and, therefore, should go to the foul sewer. Consent to discharge to a public sewer should be obtained from the local sewage company for handling at the sewage treatment works. Alternatively, such liquid waste can be directed to a catch pit with no discharge capability and collected and removed for disposal by our vacuum tankers.

We carry out interceptor integrity tests in accordance with Environment Agency Guildline PPG3. The purpose of the test is to confirm the interceptor is sound and peforming effectively and not polluting the surrounding environment. The test should be carried out every five years at the same time the interceptor is emptied and serviced with the vacuum tanker. We provide a fully equipped and qualified confined space entry team with CCTV so that the interceptor can be properly examined.

Each chamber is examined for cracks, leaks and distortion and the inflow and outflow pipes are similarly tested. A report confirming fit for purpose and recommendations, if any, is provided.

PPG3 recommends that interceptors should be checked every six months and the integrity test carried out at least every five years.
