Large Outdoor Grease Interceptor Installation in Great Falls
For high-volume commercial kitchens in Great Falls, 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 entire process, including excavation, precise placement, connection, and final inspection, ensuring a robust and compliant installation.

Gravity Grease Interceptor Installation in Great Falls, MT
Gravity grease interceptors, or GGI units, are larger, usually located outdoors, and rely on the natural difference in specific gravity between FOG and water. These are common for high-volume commercial kitchens. Our team handles the involved excavation, concrete work, and plumbing connections required for proper GGI installation, ensuring compliance with all local Montana ordinances for waste management.
Emergency Grease Trap Services in Great Falls, MT
While installation is planned, sometimes an emergency situation like a burst pipe or severe blockage may call for immediate grease trap attention. If your current system fails critically and requires urgent replacement to resume operations, DFV Plumbing offers emergency services in Great Falls, MT. We focus on rapid response to minimize downtime for your business and get your kitchen back on track.
In-Ground Gravity Interceptor Installation in Great Falls, MT
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. Some areas have expansive clay that swells when wet, which can shift foundations and stress buried pipes. 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 Brands We Install in Great Falls
DFV Plumbing installs a wide range of trusted grease trap brands known for their durability and effectiveness. We work with leading manufacturers like Zurn, Big Dipper, Schier, and Rockford Separators, among others. Our team in Great Falls can help you choose the best brand and model that fits your specific needs, budget, and local code requirements for your commercial kitchen.
Grease Trap Installation Cost in Great Falls, MT
Small under-sink hydromechanical traps generally cost much less to install than large outdoor interceptors. Indoor units are usually a few thousand dollars installed, while in-ground interceptors can run well into five figures with excavation and concrete work. Pricing depends on unit size, location, soil conditions and whether we need to cut and patch floors. We give you a written estimate that includes permits and inspection. That way there are no surprises during construction.
New Restaurant Build-Out Grease Traps in Great Falls
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.

Restaurant Grease Trap Compliance in Great Falls, MT
Making sure your restaurant's grease trap system in Great Falls, MT meets all local and state plumbing and environmental codes is crucial.

Frequently Asked Questions About Grease Trap Installation in Great Falls
The cost of grease trap installation in Great Falls, MT 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, expect to pay 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.
Signs you might need a new grease trap include frequent drain clogs, slow drainage in multiple fixtures, persistent foul odors coming from drains, or if your current unit is old, corroded, or no longer meeting local code requirements. An inspection by a professional plumber can confirm the need for replacement.
Yes, commercial grease trap and interceptor installations usually require a plumbing permit and inspection. Some cities also require approval from their pretreatment or wastewater department.
Determining the correct grease trap size involves calculating your kitchen's wastewater flow rate, fixture count, and peak operating hours. Our experienced plumbers will conduct a complete assessment of your Great Falls business to recommend the appropriate size and type of grease trap that meets local codes and your operational needs.
Installation time depends on the size and complexity of the grease trap. A small under-sink unit might take a few hours, while a large outdoor interceptor could require several days due to excavation and concrete work. We aim to complete installations efficiently to minimize disruption to your business operations.
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 cleaning frequency for a new grease trap depends on its size, the volume of FOG produced by your kitchen, and local regulations in Great Falls. Typically, grease traps require cleaning every 1 to 3 months. Regular cleaning is essential to maintain efficiency and prevent backups.
We install a variety of reputable grease trap brands, including Zurn, Big Dipper, Schier, and Rockford Separators. Our plumbers are familiar with the specifications and installation requirements of numerous manufacturers, ensuring you get a high-quality, durable system tailored to your needs.
