Residential Grease Interceptor Setup in Woonsocket, RI
While less common, some large residential kitchens or homes with extensive outdoor cooking setups may benefit from a small grease interceptor.

Gravity Grease Interceptor Installation in Woonsocket, RI
Gravity grease interceptors, or GGI units, are larger, typically located outdoors, and rely on the natural difference in specific gravity between FOG and water.

New Restaurant Build-Out Grease Traps in Woonsocket
If you are opening a new restaurant, the grease trap is often a key part of plan review. We work with your architect or contractor to size the unit and show it on plumbing plans.

We also coordinate with the city's pretreatment staff when they require a review.
Gravity Grease Trap Installation in Woonsocket

Grease Trap Installation for Schools and Institutions in Woonsocket
School cafeterias, hospitals, senior living facilities and churches with kitchens often need commercial interceptors.

Our crews schedule work around school breaks or off hours. We also provide documentation for facility managers and inspectors.

Grease Trap Sizing and Placement in Woonsocket, RI
Correct sizing and smart placement are critical for a grease trap's effectiveness.
