Grease management is the set of equipment practices and maintenance we use to keep fats oils and grease, often called FOG, out of plumbing and sewer systems. Proper grease control protects drains and mains, reduces backups, and keeps commercial kitchens compliant with local ordinances.

What grease management is

Grease management covers three things: the devices that capture grease, the operational practices that reduce grease entering the system, and the maintenance that removes accumulated material before it causes a blockage. For a restaurant that means a properly sized grease trap or grease interceptor, daily kitchen procedures that limit oil down the drain, and a documented pumping and cleaning schedule.

We work across residential and commercial settings in Riverside and the Inland Empire, with experience installing and servicing grease traps, interceptors and routine pumping for restaurants, delis and multiunit buildings.

Why grease control matters locally

In Riverside County blocked sewer lines and sanitary sewer overflows are often linked to fats oils and grease. Local plumbing codes and municipal sewer authorities require businesses that generate FOG to use approved devices and follow reporting and maintenance rules. For property managers and business owners, poor grease management can mean costly cleanups and service interruptions.

For homeowners a kitchen sink or small building drain can clog when cooking oil and congealed grease collect in the lines. Preventing that starts with understanding what should not go down the drain and having regular maintenance when a trap or interceptor is present.

Key concepts every owner should know

  • FOG. Fats oils and grease from food preparation that solidify in pipes when they cool.
  • Grease trap. A small under sink device used by light commercial or food service operations to capture FOG before it reaches the sewer.
  • Grease interceptor. A larger tank typically installed outside or underground for higher volume kitchens and commercial buildings.
  • Pumping and cleaning. Scheduled removal of accumulated grease, solids and sludge to restore device capacity and prevent carryover into the sewer.
  • Record keeping. Inspection logs manifests and maintenance records that prove compliance with local ordinances.
  • Source control. Operational steps such as scraping plates pre rinsing and using screens that reduce FOG entering the plumbing.

Grease trap versus grease interceptor

Grease trap and grease interceptor compared
Grease trap is compact and sits under a sink or in a cabinet. It is suitable for low volume operations like small cafes or bars. It requires frequent inspection and more frequent pumping if the load is high.
Grease interceptor is larger and often installed outside the building. It handles higher flows from restaurants and institutional kitchens and is sized to local code. Interceptors last longer between pumpings but need professional access for cleaning.

How we approach grease management

We begin with an assessment of your site and operations, looking at projected grease load, plumbing layout and local code requirements. That determines the right device size and location, the best access points for maintenance, and a service frequency that avoids backups.

When we install or service grease equipment we follow code compliant practices and document the work. For restaurants and commercial properties we coordinate with property managers and municipal inspectors so records are clear and accessible.

Pro tip: Simple kitchen habits such as wiping pans with paper towels before washing and using strainers in floor drains reduce the amount of grease your trap or interceptor needs to capture.

Inspection and maintenance checklist

Routine items to check

  • Visible grease level and sludge depth in the trap or interceptor.
  • Inlet and outlet plumbing for signs of carryover or bypass.
  • Gasket condition and lid seals for outside interceptors.
  • Records of past pumpings and manifests for disposal tracking.
  • Kitchen source control practices including screens and scraping stations.

Common maintenance methods and tradeoffs

There are several ways we remove grease and restore capacity. The choice depends on device size accessibility and regulatory requirements.

  • Vacuum pumping. A common method for interceptors where the tank is pumped and the interior walls are scraped as required by local regulations.
  • Manual cleaning. For small traps under sinks, the lid is removed and accumulated grease is scooped out and disposed of properly.
  • Hydro jetting. High pressure water is used in drain lines to remove hardened grease and grease rings in the mains. Hydro jetting can be effective after pumping to clear downstream lines, but it must be used carefully to avoid damaging older pipes. We offer hydro jetting for grease related blockages and preventative line cleaning when appropriate.

To learn more about hydro jetting and when it is appropriate see our detailed page on hydro jetting.

Local rules and disposal requirements

Municipal sewer agencies in Riverside County and neighboring jurisdictions set approval standards for interceptor sizing pumping frequency and disposal manifests. Many agencies require licensed contractors to produce disposal manifests and to follow hazardous waste or grease disposal pathways. We follow local requirements and file records as required by the authority having jurisdiction.

Watch out: Flushing grease down the drain or disposing of pumped material improperly can result in fines and additional cleanup obligations under local sewer rules.

Signs you need service

Be alert for slow drains odors backups or persistent grease odors near floor drains. For businesses, inspector citations or visible sheen in the sewer clean out are signs of carryover and a need for immediate assessment. For property managers, recurring complaints from tenants about smells or repeated clogs indicate system level grease issues, not just a single trap problem.

Key takeaway

Key takeaway

Grease management combines device selection source control and scheduled maintenance. For restaurants and commercial kitchens a correctly sized and properly maintained interceptor prevents backups and regulatory issues. For smaller operations and homes, consistent source control and routine trap pumping keep drains flowing.

Frequently asked questions

How often should a grease trap or interceptor be pumped?

Pumping frequency depends on device size and grease load. Small traps may need monthly service while large interceptors can go longer between pumpings. Local codes often set maximum intervals, and we size a schedule based on your operation to prevent carryover.

Can hydro jetting remove hardened grease in the sewer line?

Hydro jetting is effective at breaking up hardened grease and cleaning the inside of pipes, especially when paired with pumping of the interceptor. It should be performed by trained technicians who assess pipe condition first to avoid damage to older materials.

Who is responsible for grease maintenance in a leased restaurant?

Responsibility is typically defined in the lease and may fall to the tenant operator or the property owner. Municipal rules however hold the property responsible for preventing sewer blockages. We recommend clear lease language and documented maintenance records to show compliance.

What happens if grease is disposed of improperly after pumping?

Pumped material must be handled according to local disposal regulations. Improper disposal can trigger fines and cleanup requirements. Licensed contractors provide manifests and follow approved disposal routes.
