Large Outdoor Grease Interceptor Installation in Billings
For high-volume commercial kitchens in Billings, large outdoor grease interceptors are often required by code.

We handle the whole process, including excavation, precise placement, connection, and final inspection, ensuring a robust and compliant installation.
Food Truck Commissary and Ghost Kitchen Traps in Billings, MT
Commissary kitchens and ghost kitchens often have several prep stations and heavy dishwashing loads. We design grease trap installs that handle high flow from multiple sinks and dish machines. Each unit is sized for the combined discharge, not just one fixture. We also install cleanouts and sample ports where the city requires them. This keeps shared kitchens compliant for each tenant.
Grease Trap Sizing and Placement in Billings, MT
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 avoidable 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 Billings, MT business.
Hydromechanical Grease Trap Installation in Billings
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 tight 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.

Gravity Grease Interceptor Installation in Billings, 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 complex excavation, concrete work, and plumbing connections required for proper GGI installation, maintaining compliance with all local Montana ordinances for waste management.

Frequently Asked Questions About Grease Trap Installation in Billings
Small indoor hydromechanical traps usually cost $1,500 to $5,000 installed. Large outdoor gravity interceptors often run $8,000 to $30,000 or more with excavation, concrete and site restoration. We provide a written estimate after a site visit.
The cleaning frequency for a new grease trap depends on its size, the volume of FOG produced by your kitchen, and local regulations in Billings. In most cases, grease traps require cleaning every 1 to 3 months. Regular cleaning is essential to maintain efficiency and prevent backups.
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.
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.
We calculate flow from every connected fixture, including sinks, floor sinks and dish machines. Hydromechanical units are typically rated by gallons per minute, while gravity interceptors are sized by volume and retention time.
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 thorough assessment of your Billings business to recommend the appropriate size and type of grease trap that meets local codes and your operational needs.
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.
We recommend and install high-quality, durable grease trap brands such as Zurn, Big Dipper, Schier, and Rockford Separators. These manufacturers are known for their reliability and compliance with industry standards, offering various solutions to meet diverse commercial kitchen needs.
