Drains at commercial premises, including petrol stations, food service areas, vehicle maintenance bays, or high-traffic hardstanding, are likely handling more than just water. Fats, oils, grease (FOG), hydrocarbons and sediment regularly enter the system, posing serious operational and environmental risks without effective management.

Drain interceptors help trap these pollutants, but they only work if cleaned and maintained at the right intervals. Failing to do so can lead to flooding, sewer contamination, odour complaints, and breaches of UK environmental regulations.

At MRMS, we help commercial property owners and facilities managers across the North of England stay ahead of these issues with proactive drain interceptor cleaning. Our services not only protect business infrastructure and reputation, but they also support wider ESG and sustainability goals, from pollution prevention to regulatory compliance and corporate governance.

FOG Management Challenges Across Commercial Sectors

We work with a wide range of commercial property owners and facilities managers in sectors where FOG and related pollutants are common. Whether you manage a restaurant unit, a vehicle workshop, or a multi-tenant retail estate, we deliver reliable, scheduled maintenance to keep your drainage systems running safely, cleanly, and compliantly.

Commercial Kitchens & Restaurants

Grease, cooking oils and food waste from shopping centre food courts, catering facilities and hospitality kitchens enter the drain with every wash-down. Without regular interceptor cleaning, these materials solidify and block the system, causing backflows, smells and hygiene issues.

Vehicle Workshops & Garages

Engine oil, fuel, brake fluid and grime wash into drains from petrol stations and workshop floors in garages, body shops, MOT centres and dealerships. Interceptors trap hydrocarbons, but without scheduled emptying, they overflow and allow pollutants to enter the public sewer or the environment.

Distribution Centres & Logistics Yards

Vehicle wash-down areas and hardstanding runoff in warehouses, transport depots and service yards bring silt, fuel residues and detergents into the drainage system. These systems fill quickly, especially during wet winter months, and must be serviced more frequently to avoid overflow.

Food Processing Sites

Food Processing Sites FOG output from industrial kitchens, abattoirs and food production plants is often high and continuous. Interceptors protect local drainage infrastructure but must be maintained to prevent contamination and unplanned shutdowns.

Why Drain Interceptor Cleaning Matters

Planned preventative maintenance (PPM) for drain interceptors isn’t just good practice, it’s essential for keeping your site compliant, operational and protected from costly risks. 

  • Full compliance with environmental regulations such as PPG3 and BS EN 858
  • Reliable operations across all drainage-dependent business processes
  • Improved health and safety, hygiene and odour control across your site
  • Asset longevity through reduced wear on drainage infrastructure
  • Complete Waste Reporting for due diligence and contractor audits

How Drain Interceptors Work

Drain interceptor diagram

Drain interceptors (sometimes referred to as grease or oil interceptors, depending on their application) are essential components of commercial drainage systems. Their job is to prevent fats, oils, grease (FOG), silt, and hydrocarbons from entering the public sewer system, where they could cause blockages, environmental contamination, and legal liability.

Drain interceptors use the simple physics of gravity and water flow to remove contaminants. As wastewater enters the chamber, its flow slows down, allowing materials to separate by density:

  • Heavier solids like grit, food particles, or silt settle to the bottom.
  • Lighter substances like FOG, oils and hydrocarbons float to the top.
  • Cleaner water exits the chamber via a submerged outlet, which draws from the middle layer.

This process protects downstream pipework and stops pollutants from reaching the public sewer, watercourses, or treatment facilities. The separation process works best when interceptors are correctly sized, installed and, most critically, maintained.

Drain inteceptors are sometimes confused with grease traps, predominantly found under sinks in commercial kitchens. While grease traps are designed to prevent cooking grease from entering the drainage systems, they are limited in function and capacity, requiring regular cleaning. Both systems are necessary, working in tandem to prevent FOG from causing problems further down the line.
