Stop Clogging With Stellar Interceptor Design
Oil and Grease Trap Design
Oil and grease traps intercept and separate most greases and oils before they enter the wastewater collection system. They are common fixtures in restaurants, food service establishments, institutions with kitchens, and other commercial facilities that produce significant amounts of animal fats, oils, and grease (FOG).
They prevent clogs and blockages in piping that can lead to wastewater overflows and backups. Grease traps have baffles and flow control fittings that retain the grease in a reservoir while allowing the greywater to flow to the wastewater system.
Neville Engineering Service understands the vital role that grease traps play in commercial kitchens and food service establishments. Here are some key reasons why our top-of-the-line oil and grease interceptors are indispensably crucial:
Prevent clogged and blocked drains – Our traps catch grease before it coats and sticks to piping.
Reduce odors – Trapping grease helps minimize rancid smells from FOG buildup.
Prevent corrosion – Grease is acidic and can eat away at plumbing and sewer infrastructure if left uncontrolled.
Protect wastewater treatment – Excess FOG disrupts biological processes at municipal wastewater plants.
Avoid fines and penalties – Proper grease traps help facilities comply with wastewater ordinances and regulations.

FAQs
What is a grease trap, and why is it important?
Grease traps (or interceptors) capture and separate fats, oils, and grease (FOG) before they enter the wastewater system. They are essential in restaurants, commercial kitchens, and food service facilities to prevent clogged pipes, foul odors, corrosion, and non-compliance with wastewater regulations.
What problems do grease traps help prevent?
Neville Engineering’s grease trap designs help you:
Prevent clogged and blocked drains by capturing grease before it enters piping
Reduce odors caused by rancid FOG buildup
Prevent corrosion of plumbing and sewer infrastructure
Protect municipal wastewater treatment processes
Avoid fines by complying with plumbing and wastewater codes
Why should I choose Neville Engineering for my grease interceptor design?
With over 30 years of experience, Neville Engineering provides code-compliant, high-performance grease trap solutions. Our engineers understand the specific demands of commercial kitchens and size units based on facility type, meal volume, hours of operation, fixture count, and flow rates.
How do you size grease interceptors properly?
We use advanced sizing methods that factor in:
