Interceptor & Separator Maintenance
Compliance servicing for oil, fuel and water interceptors used in car parks, loading bays and industrial estates
Environmental Protection Through Pollution Control
Interceptors and separators prevent oil, fuel, and hydrocarbons from entering drainage systems and watercourses—protecting the environment, meeting regulatory obligations, and avoiding prosecution under environmental legislation.
Installed in car parks, loading bays, fuel stations, and industrial estates, these systems require regular servicing to maintain capacity, prevent blockages, and ensure effective pollutant removal before discharge.
Environmental Regulations & Compliance
Interceptor maintenance is governed by PPG3 (Pollution Prevention Guidelines), Building Regulations Part H, and environmental discharge consent conditions. Sites discharging surface water must demonstrate adequate pollution control measures.
The Environment Agency enforces strict penalties for pollution incidents—including prosecution, unlimited fines, and remediation costs. Duty of care obligations require documented maintenance records and proper disposal of interceptor contents.
Servicing & Maintenance Requirements
Sludge Removal
Quarterly emptying prevents capacity loss, maintains separation efficiency, and ensures interceptors continue to trap pollutants effectively.
Oil Layer Extraction
Removal of accumulated hydrocarbon layer prevents bypass and ensures continued pollutant capture before discharge to surface water drains.
Structural Inspection
Check for cracks, damaged baffles, blocked outlets, and structural defects that compromise interceptor performance or allow pollutant bypass.
Waste Transfer Documentation
Licensed waste carriers must provide waste transfer notes for all extracted materials, demonstrating compliance with duty of care obligations.
Pollution Risk & Enforcement Consequences
Neglected interceptor maintenance exposes estates to:
- →Environmental pollution: Oil and fuel bypassing interceptors contaminates watercourses, triggering EA enforcement action
- →Prosecution risk: Pollution incidents can result in unlimited fines, director liability, and remediation costs
- →Surface water flooding: Blocked interceptors cause car park and loading bay flooding during heavy rainfall
- →Insurance invalidation: Policies often require pollution prevention measures as a condition of cover
