Grease Trap Installation Cost in Denver, CO
Small under-sink hydromechanical traps generally cost much less to install than large outdoor interceptors. Indoor units are typically 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.

Gravity Grease Trap Installation in Denver
Gravity grease traps are a common and effective solution for many commercial kitchens in Denver. These passive systems use the natural separation of FOG from water due to density differences. Our plumbers are experts in installing gravity grease traps, ensuring proper sizing, correct inlet and outlet piping, and easy access for future cleaning and maintenance to maximize their efficiency.
Large Outdoor Grease Interceptor Installation in Denver
For high-volume commercial kitchens in Denver, large outdoor grease interceptors are often required by code. These large 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, delivering a robust and compliant installation.
Grease Trap Installation for Schools and Institutions in Denver
School cafeterias, hospitals, senior living facilities and churches with kitchens often need commercial interceptors. These sites usually have large dish machines and steam kettles that push high flow. We size interceptors to handle peak lunch or dinner loads without bypassing grease. Our crews schedule work around school breaks or off hours. We also provide documentation for facility managers and code officials.
Grease Trap Sizing and Placement in Denver, CO
Correct sizing and smart 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, delivering optimal performance for your Denver, CO business.
Automatic Grease Removal Units in Denver
Automatic grease removal devices skim grease from the water and collect it in a container your staff empties. Brands like Thermaco Big Dipper are popular in kitchens with limited space and frequent cleaning needs. We install these units with the correct power supply and drain connections. They can reduce the need for frequent pump-outs in smaller kitchens. We explain daily maintenance so your staff keeps the unit running well.
Gravity Grease Interceptor Installation in Denver, CO
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, maintaining compliance with all local Colorado ordinances for waste management.

New Restaurant Build-Out Grease Traps in Denver
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.

Frequently Asked Questions About Grease Trap Installation in Denver
The cost of grease trap installation in Denver, CO 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.
The main purpose of a grease trap is to intercept fats, oils, and greases (FOG) from commercial kitchen wastewater before they enter the public sewer system. This prevents pipe blockages, protects municipal infrastructure, and helps businesses comply with environmental regulations.
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 Denver, an upgrade is also a good idea.
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.
Yes, in most cases, installing a new grease trap or replacing an existing one in Denver requires specific permits from the local plumbing authority. GFR Plumbing will guide you through the permitting process, ensuring all necessary documentation is submitted and approvals are obtained before beginning work.
GFR Plumbing provides a warranty on our workmanship for all grease trap installations. Additionally, the grease trap unit itself will typically come with a manufacturer's warranty. We will provide you with all warranty details at the time of installation, ensuring peace of mind.
The timeline for grease trap installation depends on the project's scope. A simple under-sink unit might take a few hours. Larger outdoor gravity interceptors, which involve excavation and more extensive plumbing, can take anywhere from one to several days. We always aim to limit disruption to your business operations.
We install all common types of grease traps, including gravity grease interceptors, hydro-mechanical grease traps (automatic grease removal units), and compact under-sink grease traps. Our team helps you determine the best system for your commercial kitchen's specific needs and local code requirements.
