If you are wondering “is my oil interceptor fit for purpose?” you are not alone. We often have enquiries from customers who would like to know if their oil interceptor works and if it is adequate for the risks they have on site. Our compliance and suitability assessments combine our separator design consultancy with our separator integrity servicing. The output of the assessment will provide an assessment as to the functionality and suitability of the interceptor.
To test functionality of the system we undertake an integrity service/general inspection of the separator in line with BS EN 858-2:2003. You will be provided with a general inspection report meaning another integrity service should not be needed for another 5 years.
We can also perform additional checks such as sampling the discharge of the interceptor to ensure contamination is reduced to within set parameters (5 ppm class I, 100 ppm class II).
The report will detail the functionality of the system and if defects are found give advice for any repairs which may be necessary.
Your current interceptors will be assessed and compared against the required specification. If your interceptors meet or exceed the required specification you will be provided with a report validating the interceptors are fit for purpose.
If your interceptors fail to meet the requirements we can recommend further actions required. Unfortunately if inadequate interceptors have been installed it will often require replacing the old interceptor or installing additional interceptors. However remedial actions will not always require replacing the interceptor; alternative risk mitigation measures can be implemented based upon a site specific risk assessment such as making drain alterations, installing new equipment upstream of the interceptor e.g. silt traps, installing new equipment inside the interceptor e.g. interceptor high oil alarms or installing new equipment downstream of the interceptor e.g. containment valves or SUDS.
If further actions are required we can liaise with the Environmental Regulator's local Pollution Incident Reduction team to ensure they are satisfied that the proposed changes are adequate.
"The type and class of interceptor needed will depend on the activity and where the discharge is directed to."
