Grease is singled out for special attention because of its poor solubility in water and its tendency to separate from the liquid solution.
Problem with Oil/Grease in Pipes
Large amounts of oil and grease in wastewater can cause problems in collection system pipes. Grease sticks to the insides of sewer pipes, both on your property and in the streets. This decreases pipe capacity and, therefore, requires that piping systems be cleaned more often and/or replaced sooner than otherwise expected. Oil and grease also hamper effective treatment at the wastewater treatment plant.
Any type of grease, whether from businesses or residences can cause serious problems that may result in raw sewage backups and overflows in your homes or in the street. Sewer overflows pollute our rivers and streams, increase our risk to coming in contact with disease-causing organisms, and increase the costs of operation and maintenance of sewer lines and wastewater treatment.
Residents can help reduce these risks by following these simple dos and don'ts.
Collect cooking oil and grease in containers and dispose of it properly (used residential cooking oil can be properly disposed of at the City's Waste Disposal and Recycling Center at no cost)
Keep grease out of wash water
Place food scraps in a waste container for solid wastes
Remove oil and grease from kitchen utensils, equipment, and food preparation areas with scraper/towels/broom
Pour oil or grease down the drain
Use hot water to rinse grease off surfaces
Use the drain as a means to dispose of food scraps
Wash fryers/griddles, pots/pans, and plates with water until oil and grease are removed
Remember that the drain is not a trash can!
