Large Outdoor Grease Interceptor Installation in Charleston
For high-volume commercial kitchens in Charleston, 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.

Hydromechanical Grease Trap Installation in Charleston
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 without trouble.
Grease Trap Installation Cost in Charleston, SC
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 Charleston
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 Charleston
The cost of grease trap installation in Charleston, SC 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.
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 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.
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.
Indoor traps should be close to the fixtures they serve and easy to open for cleaning. Outdoor interceptors are typically placed where a pump truck can reach them without blocking customer traffic.
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 verify the need for replacement.
Grease trap installation is a complex commercial plumbing task that requires specialized knowledge, tools, and adherence to strict local codes. Attempting a DIY installation can lead to costly errors, code violations, and potential health hazards. It is always best to hire licensed and experienced plumbers like KBN Plumbing.
The primary 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.
