Environmental Control Monitoring and Maintenance

Surface Water sampling Cornwall

All companies should have environmental control measures proportionate to the risks they have on site. Our liquid pollution risk assessments will help you to identify your risks and ensure you have adequate control measures in place.

Once you have identified and installed adequate control measures it is essential to have a robust monitoring and maintenance programme in place. This will ensure your control measures are fully functioning and help to maximise the lifespan of your assets.

Site audits usually take place monthly, 6 monthly or annually and are tailored to the client’s requirements, interacting effectively with any checks conducted by internal staff. Sites we conduct these services for range from low risk commercial sites to upper tier COMAH sites.

Our robust auditing service ensures you are compliant with regulations and provides third party validation that appropriate checks are in place for verification to Environment Agency and ISO 14001 auditors.

Following an audit you will be provided with a written report detailing the condition of your environmental controls with recommendations for any corrective actions necessary.

Environmental controls audits typically consist of:

Spill Kits

Ensuring the kits are suitably located and adequately stocked to deal with the likely spills they would encounter.

Interceptors and interceptor alarms

In line with BS EN 858-2 performing checks on the suitability, condition and contents of the interceptors. We would also test the oil/silt alarms and closure devices.


Perform checks on the suitability and condition of the bunding to ensure that there are no fail points which could release liquids.


Checking bund water control units are functioning correctly to manufacturer specifications.

Shut off valves

Performing tests of shut off valves and emergency closure devices and/or conducting a more thorough annual service.

Discharge Compliance

Sampling discharges from drain outlets to measure water quality in line with discharge consents and environmental permits.

Tank & Pipe Testing

Perform visual inspections for leaks and corrosion and pressure testing where and when appropriate.

Documented Procedures

Perform checks that your site specific procedures are adequate and that they are being observed on site.


“By consolidating our bund and interceptor inspection and maintenance regime into one visit we have been able to make substantial financial and environmental savings as well as ensuring we have 3rd party validation that suitable maintenance is being conducted.”

Extracts from legislation and guidance

"If you pollute, you could get an unlimited fine, go to prison for up to 5 years, or both. You may also have to pay for the whole cost of the clean-up."

Environment Agency guidance - Pollution prevention for businesses

"You need a plan for how you’ll maintain the infrastructure of your site, and any machinery."

Environment Agency guidance - Develop a management system: environmental permits


A regular maintenance and inspection regime is essential if defects or leaks that could compromise the integrity of the primary, secondary or tertiary containment are to be identified in a timely manner. The EPR, PPC and COMAH Regulations require adequate inspection/maintenance procedures to be in place.

Being unaware of defects in the containment facilities would be no defence should a pollution incident occur."
