Top Grease Trap Cleaning in Riverside, California Ranked
For any restaurant or food service establishment in Riverside, maintaining a clean and compliant grease trap is not just a matter of kitchen hygiene-it's a critical legal and environmental responsibility. The City of Riverside enforces specific codes under its Sewer Use Ordinance to prevent fats, oils, and grease (FOG) from entering the public sewer system, where they can cause costly blockages, backups, and environmental damage. Proactive, documented cleaning by a licensed service provider is the cornerstone of compliance, helping local businesses avoid significant fines and operational disruptions while protecting the community's infrastructure.
Understanding and adhering to Riverside's regulations is essential for smooth operations. The rules are designed as Best Management Practices (BMPs) to ensure every establishment does its part.

Understanding Riverside's Grease Interceptor Regulations
Local codes mandate that all Food Service Establishments (FSEs) install and maintain approved grease interceptors or traps1. The primary rule governing cleaning frequency is clear: you must pump your interceptor when the combined FOG and settled solids reach 25% of the unit's liquid depth2 3. This is a performance-based standard, meaning the actual timing depends on your volume of wastewater and the size of your trap. While large outdoor interceptors may not exceed a 6-month cleaning interval, many establishments, especially those with high grease output, will require service more frequently-often every 3 to 4 months3 4. Small, indoor grease traps, commonly found under sinks, require much more frequent attention, ranging from weekly to monthly cleaning3.
Key Design and Accessibility Requirements
To facilitate proper maintenance and inspection, Riverside's codes include specific design mandates:
- Easy Access: Grease interceptors must be readily accessible for service and inspection by city personnel2 5.
- Proper Venting: Units must be properly vented after the sample box to prevent airlocks and allow for efficient pumping2.
- Correct Installation: All installations must be approved through the city's plan check process to ensure they meet current standards1.
The Critical Role of Licensed Haulers
One of the most important regulations for Riverside restaurants involves waste handling. All grease waste-including used fryer oil from cooking-must be collected by a state-approved, licensed Inedible Kitchen Grease (IKG) hauler3 6. It is illegal to pour any oils or grease down drains, into dumpsters, or onto the ground. Using a licensed hauler ensures that grease is recycled or disposed of properly, and it provides you with the necessary documentation, or manifests, to prove compliance during inspections2 7.
Consequences of Non-Compliance
Failing to use a licensed service or improperly disposing of grease can lead to severe consequences. Enforcement actions are typically triggered by sewer overflows, complaints from neighbors, or during routine inspections conducted by the city's Sewer Inspection Program4 8 9. Penalties can include:
- Substantial fines.
- Mandatory, immediate clean-up at your expense.
- A requirement to implement a formal BMP plan.
- In severe cases, suspension of sewer service.
Inspection Schedules and Maintaining Records
The City of Riverside and county agencies conduct inspections to ensure compliance9. These can be scheduled or occur randomly, and they often follow a report of a problem like a sewer overflow4 10. During an inspection, officials will check both the physical condition of your grease interceptor and your maintenance records.
Your cleaning manifests from a licensed hauler are your primary proof of compliance. Keeping these documents organized and on-site is non-negotiable. Inspectors will verify that cleaning is occurring at the required frequency (before FOG/solids hit 25% capacity) and that a licensed provider is performing the work2 8.

Understanding Service Costs and Scheduling
Investing in regular grease trap maintenance is far more cost-effective than dealing with emergencies, fines, or sewer damage. Costs vary based on the size and type of your interceptor, its location, and how often it needs service.
- Regular Scheduled Service: For a standard large, outdoor grease interceptor, a scheduled pumping service in Riverside typically ranges from $250 to $400 or more per service11 12. Smaller, under-sink traps may cost between $125 and $200 per cleaning11. Establishing a regular service schedule (e.g., quarterly) with a provider can often manage costs effectively.
- Emergency or One-Time Service: Responding to an overflow or a last-minute compliance order is significantly more expensive. Emergency pump-out and cleaning services can cost between $800 and $1,200 or more, depending on the severity of the situation and the required clean-up11 12.
Best Management Practices for Riverside Restaurants
Beyond hiring the right service, daily kitchen practices are your first line of defense. Riverside's BMP guidelines recommend2:
- Scrape, Don't Rinse: Scrape food scraps into the trash or compost before washing dishes.
- Use Collection Containers: Place fryer baskets and greasy pans in a dedicated container to cool and drain before washing.
- Train Your Staff: Ensure all kitchen employees understand the importance of keeping FOG out of the drains.
- Post Clear Signs: Place "No Grease" reminders near sinks and dishwashing areas.
- Have an Emergency Plan: Know the procedure and contacts for immediately shutting off water and contacting your plumber or grease pumper if an overflow occurs2.
Adopting these practices minimizes the load on your grease trap, extends time between necessary pumpings, and demonstrates a good-faith effort to comply with local codes.
The Importance of Proper Grease Interceptor Design
If you are opening a new restaurant or renovating your kitchen, working with a knowledgeable professional during the plan check phase is crucial1. The size and type of interceptor must be correctly calculated based on your anticipated wastewater flow and grease production. An undersized trap will require impossibly frequent cleaning, while design flaws can lead to chronic problems. Ensuring your system has proper venting and is easily accessible from the start will save countless headaches and costs over the life of your business2 5.
