Why Proper Grease Trap Installation Matters
An adequately sized grease trap in the right position is an essential method for the effective management of grease in commercial kitchens. Proper installation ensures efficient grease separation while allowing easy access for inspection, cleaning and maintenance, supporting reliable drainage performance and long-term kitchen operations.
On the other hand, an undersized system installed incorrectly will likely allow FOG to enter into mains water supplies. This will lead to FOG build up, causing blockages, odours, hygiene concerns and operational disruptions.
Commercial Grease Trap Installations in the UK
Our commercial grease trap installation service also covers the initial assessment, expert recommendations, supply and installation of systems for appropriate commercial premises across the UK. Our engineers have years of experience in the practical requirements of keeping site disruption to a minimum, with installation quality to a maximum.
Every kitchen is different, so we consider factors like general wastewater flow, FOG output, available space, drainage arrangements and maintenance access before recommending a system.
So arrange your free Aqua Mundus site survey today or explore our Grease Traps range or use our Grease Trap Size Calculator as a starting point.

Choosing the Right Grease Trap for Your Installation
Selecting the right grease trap option has numerous considerations including kitchen types, output, wastewater flow, FOG loads, available internal space, existing drainage and more. Options for future cleaning, access and any potential changes to kitchen layout should also be kept in mind too.
A passive grease trap will separate FOG from wastewater as it passes through the unit, while an automatic recovery system uses a different method to remove collected grease. The Aqua Mundus grease trap size calculator can help you determine the ideal option for your situation.

Hospitality & Commercial Kitchens
Hotels, pubs, catering facilities and other commercial kitchens may need systems capable of handling different service volumes throughout the day. See our Commercial Kitchens page.
Education
Schools, colleges and other education sites may operate kitchens serving large numbers of meals within concentrated service periods.

Industries We Work With
Grease Trap Installation & FOG Compliance
Legislation like Section 111 of the Water Industry Act 1991 restricts the discharge of matter into a public sewer where it may interfere with the free flow of the sewer system or the treatment of content disposal.
For commercial food operations, suitable grease management can help control fats, oils and grease before they enter drainage systems.
This does not mean that the legislation universally requires every commercial kitchen to install a specific type of grease trap. The appropriate solution depends on the individual premises and operation.
