Grease that is poured down your kitchen sink can cling to the inside of your household plumbing and the pipes that make up our Sewer System. Overtime, the grease can build up so much that it clogs pipes completely. When wastewater can’t move freely through the sewer system due to a blockage, it can cause flooding and even a Sewer Backup into your home! By disposing of household grease properly, you can help avoid expensive repairs and unnecessary disruptions to residences and businesses.
For information about how to safely dispose of grease as a food service establishment, visit Disposing of Grease as a Business. To learn about how to properly dispose of other household waste, visit Safe Disposal of Harmful Products.

Service stations are required by State law to accept up to five gallons of used motor oil per person, per day, at no charge. Remember not to mix your motor oil with any other substance.
No subtance any kind should ever be poured down a catch basin, storm sewer, or street drain. If you witness someone disposing of any product into a street drain, call 311 or file a report online.
