Commercial Grease Traps
Over 70% of sewer blockages are caused by fats, oils, and grease (FOG), making grease traps essential for commercial kitchens and food service establishments. Gainey’s commercial grease traps are engineered to intercept and retain liquid grease and waste, allowing for effective separation before it enters the sewer system. This process helps prevent blockages, protects plumbing infrastructure, and keeps your operations running smoothly. Designed for durability and efficiency, our grease traps are ideal for fast food outlets, restaurants, and any facility that manages high volumes of greasy waste.

Frequently Asked Questions:
What size grease trap do I need for my project/application?
Sizing depends on flow rate, fixtures connected, restaurant capacity, and local code requirements. Gainey’s helps engineers, contractors, and owners determine the correct size based on your kitchen load, regulatory standards, and performance needs so you stay compliant and avoid backups, overflows, and unnecessary maintenance. Try out our sizing calculator.
Will this grease trap meet local code and health department requirements?
Yes. Gainey’s precast grease traps are designed to meet or exceed local parish, municipal, and state regulatory requirements, including plumbing codes and health department standards. If your jurisdiction requires approvals or submittal documentation, we can provide design information (with the help of outsourced engineer partners).
How is the grease trap designed structurally and how durable is it long-term?
Our grease traps are built using steel reinforced precast concrete, out-source engineered for structural integrity, watertight performance, and long-term durability in demanding soil and groundwater conditions. Our concrete mixes resist corrosion, deformation, floatation, and collapsing far better than lightweight materials like plastic or fiberglass, meaning decades of dependable service.
How flexible are the inlet/outlet connections and configurations?
We offer flexibility to match real-world site conditions. Grease traps can be produced with a variety of pipe sizes, elevations, and orientations. Openings can be precast, cored, or supplied with boots, sleeves, or grout connections depending on project design. Our team works with you to ensure the correct configuration without compromising structural integrity.
How often does it need to be pumped and maintained?
Maintenance depends on usage, restaurant size, menu type, and local regulations. Most facilities pump monthly or bimonthly. Properly sized tanks reduce how often maintenance is required and help prevent odors, clogs, and downtime. Local health departments may also require documented maintenance, so installing the right system matters.
How fast can I get it and how easy is it to install?
Because our systems are precast and built in advance, they can be delivered quickly. Installation is straightforward for contractors and typically much faster than poured-in-place solutions, often completed and backfilled in the same day depending on site conditions. Our team coordinates closely with your contractor to keep the project on schedule.
