Defend Your Drains
Fats, Oils & Grease
When FOG (Fats Oils and Grease) is washed down the drain it sticks to the insides of pipes, then solidifies and can create large clumps blocking the sewer lines and your personal pipes. This can lead to sewer backups into the streets, homes, and local waterways. Pouring your used cooking oil outside is also very harmful to the environment and wildlife. Make a difference in your community and please dispose of it responsibly.
Do not put FOG down the drain, instead:
- Put liquid oil and grease in a sealable container and put it in the trash
- Remove leftover grease from pans with a paper towel after it has cooled
- Avoid using the garbage disposal and put all food in the trash
- Rinse greasy dishes with cold water before putting them in the dishwasher
- Filter, freeze and reuse cooking oils
- Used FOG can also be recycled into many different products (EX: animal feed, biodiesel)
Recycle Cooking Oil
The City of Princeton Public Works accepts used cooking oil year-round! Bring the oil in a covered container, and please filter your used cooking oil beforehand.
Trash It, Don't Flush It
Wipes, cleaning cloths, paper towels, feminine hygiene products, and personal care items-these common household items don't break down in the sewer pipes of your home or on the way to the wastewater treatment plant. So what happens when you flush them down the toilet or drain? Since they don't break down, they can tangle and clump together. This can clog pipes and cause sewage to back up into your home or neighborhood. Even items labeled "flushable" can clog sewer pipes. Defend your drains by disposing of these products in the trash (where they belong) before they cause an unpleasant and expensive problem.
