Fat Oil and Grease: Smart Ways to Stop Restaurant Buildup

Sacramento restaurants live and die by flow. When sinks, floor drains, and dish lines move, service moves. When they slow, tickets pile up and guests wait. The quiet culprit is fat oil and grease building up inside pipes and traps. Left alone, it hardens on pipe walls, accumulates over time, and catches food particles, leading to blockages.
This accumulation can cause backups, infrastructure issues, and even environmental hazards. FOG often enters through kitchen drains, especially from cooking in restaurant kitchens. You can stop it with simple habits, the right equipment, and a repeatable schedule supported by Sacramento Grease
You will see quick wins in hours, not months. Start by capturing FOG at the source in your commercial kitchen, then maintain interceptors on a fixed cadence, and train your team to develop good habits that stick.
This guide keeps jargon to a minimum, provides checklists you can post on the wall, and shows how to avoid fines and closures with clean records and straightforward documentation. Controls that limit fats, oils, grease, and fog in sewers are a key part of national best practices and local programs, which means your kitchen benefits and your city’s system stays safe.
What Is Fat Oil and Grease Control for Restaurants?
Restaurant fat, oil, and grease control involves capturing FOG at the source, preventing it from entering drains, and maintaining interceptors on a regular schedule. This can be achieved by scraping plates, dry-wiping cookware, using strainers, sizing and servicing interceptors, and providing staff training. These steps prevent blockages, odors, and fines.
Fat Oil and Grease Control: Keep Sacramento Kitchens Open
Fog wastewater rises anytime hot oils cool on pipe walls. As the temperature drops, FOG congeals and narrows the pipe, leading to a buildup of fats, oils, and grease inside sewer pipes. Add solids and you get a stubborn clog. For restaurants, the fix is a closed loop: capture, contain, and maintain. EPA guidance emphasizes controls that limit FOG as a key strategy for reducing sanitary sewer overflows and safeguarding the sewer system from FOG-related issues.
Why FOG Builds Up And How It Damages Drains
- Hot fryer oil cools and hardens in lateral lines.
- Sauces, dairy products, and meat fats tend to stick to rough pipe surfaces.
- Small particles bind to FOG, creating a thick mat in traps and lines.
- Interceptors without routine pumping let grease push downstream to the main.
- Local agencies and utility programs warn that these blockages increase during peak seasons.
FOG blockages can lead to sewer overflow, resulting in environmental contamination and public health risks. If not properly managed, untreated FOG may be discharged into the environment, making it essential to control and prevent such discharges.
How To Stop FOG At The Source
Use this short list to cut grease buildup before it reaches your plumbing.
Pro tips
- Scrape plates into the trash and dry-wipe cookware before washing the sink.
- Use sink strainers and empty them into solid waste containers.
- Keep a dedicated bin for cooled, used cooking oil and label it for recycling. Proper management of used cooking oil from food preparation, meat fats, and products like mayonnaise and salad dressings helps prevent sewer blockages and environmental contamination.
- Post a one-page FOG policy at the dish and prep areas for fast training.
Watch-outs
- Do not flush emulsifiers that promise to “dissolve” oil or grease. They often re-solidify downstream.
- Do not rinse hot oil with very hot water and hope it passes. It usually cools and hardens in the lateral line.
Daily Line-Check: 10-Minute FOG Routine
- Trash liners are in place at the dish and prep areas.
- Scrapers and towels set for dry-wipe.
- Strainers are seated in all pre-rinse sinks.
- Grease caddy empty and lids tight.
- Spill kit stocked near the fryer and grill.
- Staff signs the FOG log at the end of the shift.
Interceptor Sizing, Service Intervals, And Logs
The right size and right schedule are your safety net. Many agencies provide sizing guidance and expect food service establishments to maintain records, train their staff, and keep service logs on-site. Use a calendar and a binder by the dish area so you can show proof during inspections. Participation in a local or statewide FOG management program can help ensure compliance with these requirements and support best practices.
Checklist
- Confirm the interceptor size and model in your equipment list.
- Set a pumping frequency based on load. Heavy fry kitchens often pump every 30 to 60 days.
- Keep a three-ring binder with manifests, photos, and before-and-after notes.
- Log grease depth monthly and schedule service before the 25 percent rule is exceeded.
- Book a quarterly line jet if you run high-fat menus or see recurring slow drains.
- Add a trained backup contact who can authorize emergency service.
DIY vs service
- DIY tasks: scraping, dry-wipe, strainers, label bins, and log sheets.
- Professional service: pumping, hauling with manifests, hydro-jetting, camera checks, and interceptor maintenance that meets local pretreatment expectations. Programs and ordinances exist to keep FOG out of sewers and protect public infrastructure, including publicly-owned treatment works, from blockages and damage.
Staff Training And Kitchen Workflow
Train where the action happens. A five-minute tailgate talk at the dish area beats a memo. Sacramento utilities provide simple training materials that you can adapt for your team. Post a one-page standard near the dish machine and the fryer, and review at pre-shift twice a week for the first month.
Make it stick
- Assign a FOG captain per shift.
- Audit stations with a two-minute checklist.
- Reward clean strainers and complete logs with shout-outs.
Station-By-Station Controls That Actually Stick
- Prep: keep scrap bins within arm’s reach.
- Grill: scrape to a cool pan, not the floor sink.
- Fryer: filter, cool, then decant to a labeled caddy.
- Dish: dry-wipe, strain, and log.
- Porter: Check the FOG binder before clock-out
Compliance And Local Rules In Sacramento
Restaurants in Sacramento County are inspected in accordance with both local and state health codes. Many local communities also participate in FOG management and education programs to help prevent sewer blockages and protect water quality. Inspectors look for sanitation, proper waste handling, and evidence that you manage FOG. Keep manifests and logs handy and train a lead to answer questions.
Local resources
- County Environmental Management for food protection and inspections, helping to prevent FOG from entering local waters.
- Regional sewer agencies with food service guides and training sheets that support the protection of area waters from FOG contamination.
- Nearby city programs that show best practices for residents and businesses disposing of oil and grease, reducing the risk of polluting local waters.
What Inspectors Look For
- Clear evidence of source control in the kitchen is evident.
- Interceptor on a routine schedule with recent manifests.
- No visible FOG in floor sinks, trench drains, or cleanouts.
- Inspectors check for practices that maintain water quality by preventing FOG from entering the wastewater system.
- Trained staff who can explain the process and show records. Guidance from EPA and state pretreatment programs supports this approach.
Costs, Savings, And Quick ROI
Small habits pay off fast. Kitchens that scrape, dry-wipe, and strain cut pump frequency and emergency calls. Add a scheduled service, and you cut risk even more. National guidance emphasizes that limiting sewer grease upstream is more cost-effective than addressing clogs or overflows later.
Example
- Without controls, a single emergency backup can cost more than several months of regular pumping and cleaning, resulting in significant expenses for businesses and the community over the course of a year.
- With controls, fewer slow drains, fewer odor complaints, and less downtime, resulting in significant annual cost savings.
DIY Tasks vs Professional Service
- DIY: daily scraping, dry-wiping, strainer checks, bin labels, log sheets, station audits.
- Professional: interceptor pumping, hydro-jetting, video line inspection, manifest management, and compliance support with Sacramento Grease that help protect wastewater systems and support effective treatment.
Common Mistakes And Myths To Avoid
- “Hot water carries grease away.” It hardens downstream.
- “Additives make grease disappear.” They move the problem to the main line.
- “We clean when it backs up.” Preventive control is cheaper and safer.
- “Small kitchens do not need a schedule.” Even light FOG builds up.
- “Only the dish area matters.” Grill and fryer habits drive the load.
- “Logs are busywork.” Logs speed up inspections and protect you.
Improper FOG disposal can negatively affect plumbing by causing blockages and backups. It also affects the environment by polluting water systems and harming local ecosystems. These issues can impact public health by increasing exposure to contaminants and disease-causing pathogens. In severe cases, FOG pollution can reach and contaminate drinking water sources, making it essential to manage FOG properly.

FAQs About fat oil and grease in restaurants
How often should an interceptor be pumped?
Set frequency by load. Heavy fry kitchens often pump every 30 to 60 days, then adjust based on logs and inspections.
What should staff do before dishes hit the sink?
Scrape and dry-wipe into the trash, then use strainers. This removes most FOG and solids before water comes into contact with the wares.
What are fats, oils, and grease (FOG), and why are they a problem?
Fats, oils, and grease (FOG) are byproducts from cooking and food preparation that can enter sewer systems if not managed properly. When FOG is disposed of down the drain, it can accumulate and block sewer systems, leading to costly maintenance, environmental harm, and overflows that spill into streets and cause public health hazards.
Do enzymes or additives solve FOG problems?
They can move FOG downstream where it cools and hardens. Source control and scheduled service are safer.
What records should I keep for inspections?
Service manifests, depth measurements, photos, and a simple monthly log are kept in a binder near the dish area.
Does hot water help remove grease?
It may appear to work, but the grease cools in the lateral line and adheres to the pipe walls. Avoid this practice.
Who can help me set the right schedule?
Sacramento Grease can review the menu, volume, and current logs to set intervals, start your binder, and train your team.
