Hydromechanical Grease Trap Installation in Somerville
Hydromechanical grease traps sit under or near sinks and use baffles and flow control to separate grease from water. They are common in small cafes, coffee shops and quick-service restaurants with limited space. We install units from Zurn, Watts, Schier and Endura sized by gallons per minute. Each install includes a flow control fitting and proper venting to keep the trap working as designed. These units need frequent cleaning, so we place them where staff can reach the lid easily.
Large Outdoor Grease Interceptor Installation in Somerville
For high-volume commercial kitchens in Somerville, large outdoor grease interceptors are often required by code. These substantial units are installed underground and designed to manage significant amounts of FOG before wastewater enters the municipal sewer system. We handle the whole process, including excavation, precise placement, connection, and final inspection, ensuring a robust and compliant installation.
New Restaurant Build-Out Grease Traps in Somerville
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 then install it during rough-in so it is ready for inspection. Getting the trap right early avoids costly changes after the slab is poured. We also coordinate with the city's pretreatment staff when they require a review.
In-Ground Gravity Interceptor Installation in Somerville, MA
Larger restaurants and high-volume kitchens often need an outdoor gravity interceptor. These concrete or polyethylene tanks typically range from several hundred to over 1,500 gallons. We excavate, set the tank on a stable base, connect inlet and outlet piping and install manhole risers. Tree roots and shifting fill around old clay or cast iron sewer laterals are a frequent cause of backups in established neighborhoods. We plan excavation equipment around the ground conditions we find on site. A properly installed interceptor can go much longer between pump-outs than an indoor trap.
Grease Trap Sizing and Placement in Somerville, MA
Correct sizing and strategic placement are critical for a grease trap's effectiveness. Installing a unit that is too small will lead to frequent clogs and overflow, while an oversized one can be an unnecessary expense. Our plumbers carefully calculate the required capacity based on your kitchen's water flow, fixture count, and operating hours, ensuring optimal performance for your Somerville, MA business.

Frequently Asked Questions About Grease Trap Installation in Somerville
The cost of grease trap installation in Somerville, MA varies widely based on the type and size of the trap, whether it's an indoor or outdoor unit, and the complexity of the installation. For a small under-sink hydro-mechanical unit, plan on between $1,500 and $4,000. Larger outdoor gravity interceptors can range from $7,000 to $20,000 or more, including excavation and concrete work.
While the terms are often used interchangeably, 'grease trap' usually refers to smaller, indoor hydro-mechanical units, often found under sinks. 'Grease interceptor' usually refers to larger, outdoor gravity-fed units with higher capacities. Both serve the same purpose of separating FOG from wastewater.
Manufacturer warranties vary, with many polyethylene units carrying long structural warranties. We also warranty our installation workmanship and connections.
An indoor under-sink trap can often be installed in a day. Outdoor interceptors typically take several days to a week or more, depending on excavation, concrete work and inspection scheduling.
Signs you might need a new grease trap include frequent sewer backups, persistent foul odors coming from drains, slow drainage throughout your kitchen, or if your current unit is visibly corroded or leaking. If your existing trap is old and no longer meets current local codes in Somerville, an upgrade is also advisable.
That depends on local rules and the trap type. Some programs require dish machines to discharge through the interceptor, while others restrict high-temperature discharge into certain units, so we confirm the requirement before we install.
The lifespan of a grease trap depends on its type, material, and how well it's maintained. Steel grease traps may last 10 to 15 years, while durable fiberglass or polyethylene units can last 20 to 30 years or even longer. Regular cleaning and proper usage are key to lengthening its lifespan.
BWM Plumbing stands behind our work with a comprehensive warranty on all grease trap installations. The specific warranty period will be outlined in your service agreement and usually covers parts and labor for a designated timeframe. Manufacturer warranties also apply to the grease trap unit itself.
