A grease interceptor works only when it is properly selected, connected, accessible, maintained, and emptied before accumulated fats, oils, grease, and solids reduce its effective capacity.
Scheduled or one-time pumping for accessible hydromechanical and gravity grease interceptors, with site-specific preparation and handling.
Authorized interior cleaning and a practical condition review after contents are removed and internal components are visible.
Recurring service built around actual accumulation, operating conditions, manufacturer guidance, and the governing wastewater authority.
Planning and installation for approved grease interceptors based on connected fixtures, flow, food-service operation, location, and code requirements.
Replace failed, inaccessible, undersized, damaged, or noncompliant equipment after verifying the existing system and current approval requirements.
Evaluation, cleaning, repair, or replacement planning for the approved grease-waste piping serving the interceptor.
Grease systems separate light FOG at the top and heavy solids at the bottom. Effective pumping addresses the full contents and makes the internal condition visible for inspection.
Confirm service location, protect the work zone, open approved access points, and assess immediate conditions.
Remove FOG, wastewater, and settled solids in accordance with the authorized service scope.
Document accessible baffles, tees, walls, lids, seals, and conditions requiring repair or further evaluation.
Secure access, record service details, and transport the material to an approved receiving or disposal facility.
“Grease trap” is a common term for different devices. The approved equipment, size, fixture connections, location, and maintenance access must match the food-service operation and governing requirements.
Compact listed equipment that uses flow control and internal separation features. Selection must follow the approved fixture flow, manufacturer listing, installation instructions, ventilation, access, and wastewater-authority requirements.
Large-volume equipment typically installed underground. Design must account for capacity, invert elevations, structural loading, access covers, groundwater or buoyancy, excavation, traffic rating, sampling, pumping access, and restoration.
Final selection and installation must follow the adopted plumbing code, wastewater or FOG-control authority, permit, approved plans, manufacturer listing, and actual site conditions.
Request Site Evaluation →Menu, production, hours, seating, warewashing, and expected FOG and solids loading.
Approved sink, drain, dishwasher, disposal, and equipment connection schedule—never assumed.
Fixture flow, retention, manufacturer rating, code sizing method, and wastewater-authority criteria.
Grease waste, venting, flow controls, cleanouts, sampling points, and required monitoring provisions.
Safe opening, pumping, inspection, replacement, clearance, odor control, and equipment access.
Elevation, excavation, utility conflicts, groundwater, traffic loads, supports, haul-off, and restoration.
Overflow, odor, slow drainage, frequent line cleaning, and damaged components can indicate overdue pumping, excessive loading, a failed interceptor, or a separate piping problem.
Request Grease-System Service →Sinks, floor fixtures, or grease-waste branches drain slowly or back up during peak use.
Persistent odors, grease around access covers, or evidence of overflow requires prompt review.
FOG and solids reduce the interceptor’s effective working volume before the scheduled service date.
Missing baffles, deteriorated tees, failed lids, corrosion, cracks, or unsafe access affect performance.
Wastewater notices, failed inspections, or poor service records indicate a program or equipment gap.
New menus, equipment, hours, seating, or production can increase loading beyond the original basis.
Service frequency should follow the controlling wastewater authority, permit, manufacturer requirements, actual FOG and solids accumulation, operating changes, and site history—not a generic calendar alone.
Build a Maintenance Program →Document equipment, access, capacity, condition, accumulation, current schedule, and open defects.
Coordinate service windows, keys, alarms, loading docks, traffic, odors, and kitchen shutdowns.
Maintain service dates, quantities where available, condition notes, photos, receiving records, and repairs.
Shorten or extend intervals only when authority requirements and documented accumulation support the change.
Pumping and installation follow different field paths, but both begin with clear access, authority requirements, and an approved scope.
Confirm property, equipment type, capacity, location, access, service history, and immediate condition.
Review authority, permit, disposal, fixture, design, access, schedule, and site responsibilities.
Separate pumping, cleaning, repairs, installation, excavation, restoration, and third-party work.
Protect the site, complete the approved service, and document concealed or changed conditions.
Secure covers, verify operation where applicable, record service, and identify remaining actions.
These general answers help with planning. The adopted code, wastewater or FOG authority, permit, manufacturer instructions, approved design, and site conditions control the actual work.
Questions?240.392.3535The required interval varies. Follow the controlling wastewater authority, discharge permit, manufacturer, and actual accumulation. Many programs use a FOG-plus-solids threshold—often called a 25% rule—but the local requirement and documented site condition control.
“Grease trap” is often used generally. Hydromechanical grease interceptors are typically smaller, listed devices using flow and separation features. Gravity grease interceptors are generally larger tanks relying on volume and retention time. Approval and sizing differ.
A complete pump-out addresses floating FOG, liquid contents, and settled solids within the authorized service scope. Removing only the top layer leaves solids and reduces the ability to inspect the equipment.
Do not treat additives as a substitute for required pumping. Their use may be restricted by the wastewater authority and can move grease downstream rather than remove it from the system. Use only products and methods specifically allowed for the site.
The approved connection schedule depends on the adopted code, wastewater authority, plans, equipment, and food-service operation. Sinks, dishwashers, disposals, floor fixtures, and other equipment should never be assumed connected or excluded without review.
No. Location must support approved drainage, venting, flow control where required, structural loading, safe access, pumping, odor control, inspection, clearances, excavation, utilities, and future replacement.
Pumped contents must be transported and delivered to an approved receiving, treatment, recycling, or disposal facility in accordance with applicable hauler, wastewater, environmental, and recordkeeping requirements. It is not disposed of onsite.
Share the property, equipment type, size if known, service history, access, symptoms, and operating schedule. For an active overflow or backup, call directly.
