Restaurant Best Management Practices (BMPs)
Activities within our watersheds have a direct impact on our rivers and streams. These restaurant Best Management Practices help prevent restaurant pollution from going down storm drains and into our rivers, lakes and streams.
When restaurant wastewater polluted with detergents, disinfectants, trash and grease from food preparation and clean up enters storm drains, it flows, untreated, into neighboring creeks. Using best management practices assures that oils, food wastes, fatty substances, and trash do not flow into a nearby storm drain.
Other potential sources of restaurant pollution include a leaking waste grease container and a leaking garbage dumpster. These two sources of restaurant pollution can be curtailed by installing a proper dumpster pad that drains to the City’s sanitary sewer system along with a dumpster cover that keeps the rain out of the sanitary sewer system.

Maintaining a clean environment is a priority for restaurants. The following are environmentally friendly practices both indoors and out.
- Pour wash water into a janitorial or mop sink, not a dish washing sink. Don’t pour it out onto a parking lot, alley, sidewalk or street. Oil and grease can cause sewers to be clogged.
- Recycle grease and oil instead of dumping down the drain. Rendering services are available to sample grease for pesticides and other chemicals before it can be resold.
- Check your outdoor cleaning. If you use cleaning products or detergents, you should mop up wastewater or capture it with a portable pump or a wet vacuum. Pour the water into a janitor sink or a sanitary sewer if approved of by the local sanitary sewer authorities. Train outside cleaning contractors on company cleanup practices.
- Clean floor mats, filters, and garbage cans in a mop sink or floor drain. Don’t wash them in a parking lot, alley, sidewalk, or street. The oils can travel into drains and pollute stormwater.
- Inspect dumpsters and grease traps for leaks.
- If strong chemicals are sprayed on roof-mounted equipment (vents, air conditioning coils, etc.), they will flow from the roof drains into the storm drain and end up in the nearest creek. Collect the wastewater and pour it into a mop sink or sanitary sewer clean out.
