Grease Trap Cleaning

Safe waste disposal solution

Grease traps are an essential part of any commercial kitchen or food processing plant and help with grease management by capturing harmful fats, oils and greases (FOG), preventing them from entering the sewer where they could cause potential damage or blockages.

Without proper grease trap maintenance and cleaning, grease deposits can build-up quickly inside the traps, making them ineffective. The accumulation of the grease can also make it very difficult to dispose of and become a source of unpleasant odours. Our grease trap cleaning service helps to stop blocks in drains and malodours by cleaning out and safely disposing of the waste.

Frequently Asked Questions about Grease Traps and Grease Trap Cleaning

  • How does a Grease Trap work?

    Whether you are cooking in a residential or commercial catering environment, all types of cooking generate waste that can flow down the sink through the pipework. If left unchecked, the build-up of fats, oils, and grease (FOG) and food waste can build-up, potentially leading to blockages. Commercial fat traps or grease traps are specially designed plumbing drainage devices used to intercept wastewater before entering the water disposal system.

    Within a commercial kitchen or food processing plant, grease traps form a vital role in helping to ensure harmful FOGs are captured and removed before entering the system where they could cause potentially damaging obstructions, also known as fatbergs but with continuous use, grease can build-up very quickly inside grease traps making them ineffective.

  • Does UK law require Grease Traps?

    For commercial kitchen facilities across the UK, several regulations and legislations form part of the owners' and proprietors' duty of care for managing and disposing of FOG produced as part of their business operations.

    • The British Building Regulations (document H, section 2.21), commercial food premises state regulations for grease management. Under regulations, a commercial food premise connected to the mains drainage system serving hot food should be fitted with a grease trap or separators complying with BS EN 1825-1:2004. Grease Traps and Interceptors must be provided by law to a range of facilities, including Restaurants, Cafes, Fast Food Restaurants, Food Processing, and Commercial Kitchens.
    • Under the Water Industry Act 1991, it is a criminal offence to discharge any matter that may interfere with the free-flowing of wastewater into public sewers systems.
    • Every commercial premise is also responsible for arranging the collection and disposal of waste (including waste cooking oils and fats). It must comply with the requirements of section 34 and Duty of Care of the Environmental Protection Act 1990.
    • The Food Safety Act 1990 states that drainage problems or blockages caused by the effects of fat, oils and grease (FOG) within drains that result in failure to comply with the Food Hygiene Regulations could result in prosecution, fines or imprisonment or give grounds for an emergency prohibition order.

  • How often should a Grease Trap be emptied and cleaned?

    As part of your Grease Trap Cleaning Procedure, grease traps should be emptied and serviced regularly depending on the volume of effluent passing through the unit.

  • Is Grease Trap waste controlled waste?

    Yes, waste from grease traps is classified as controlled waste. The Environment Agency or an Environmental Health Officer is required to see evidence that regular cleaning of the grease trap has been performed and a registered waste carrier disposes of any waste that has been removed.

  • How do you prevent drain blockages and fatbergs?

    Clogs or blocks in your pipework are entirely avoidable. Also, don't pour fats, oils, or grease down the drain. These cooking by-products can cause a build-up entering the wastewater drainage system, forming semi-solid waste or fatbergs.

    Avoid pouring or overloading your grease trap system by regularly maintaining your drains and pipes, preventing drains from clogging. Even a well-maintained system can be at risk of blockage, but using a preventative maintenance service can stop FOG and other contaminants from accumulating in your pipework.

    Rentokil Specialist Hygiene’s biological dosing service periodically feeds kitchen drain pipes and grease traps with a biological solution containing environmentally controlled bacteria, which can safely break down the grease and prevents a build-up from occurring.

Drain Blockage Prevention - Biological Dosing Service

Our Biological Dosing drain blockage prevention solution periodically feeds kitchen drain pipes and grease traps with a biological solution containing environmentally friendly bacteria and enzymes, which break down the grease and prevents the build-up from occurring.

This regular dosing provides protection against blockages, offensive odours, flooding, and associated repercussions. Our compact battery-operated unit is unobtrusive and programmed to match the volume and frequency of doses to suit your daily serving times and kitchen routines. The dosing intervals can be increased during peak times to maintain optimum protection.

Following installation, our team can carry out scheduled maintenance visits to check the condition of the drainage system, top up fluid and ensure the dosing system is operating effectively. In addition, the automated solution reduces the use of traditional drain-clearing techniques and extends the life of the pipework whilst decreasing the frequency of grease trap emptying.
