Tips for Protecting the Environment

Keep Fats, Oils & Grease (FOG) Out Of Your Sewer!

Never pour fats, oils, or grease (FOG) down your household drains or into storm drains! Blockages in sewer lines can cause backups into your home with expensive cleanup costs. Overflows may cause grease to enter our creeks and bay, harming wildlife and the environment. Grease poured into gutters or storm drains flows directly to local waterways without treatment.

Read our Holiday Tipsheet for ways to dispose of Fats, Oils & Grease properly! Protect your sewer and the environment.

Bring your used cooking oil and grease to Allied Waste's Customer Service Center for FREE disposal Monday through Friday from 8 a.m. to 5 p.m. Take it to the self-serve drop-off at 42600 Boyce Road in Fremont (between Stevenson and Auto Mall Parkway), and it will be recycled into useful products. Dispose of solidified grease in your trash.

For more information, call Allied Waste at (510) 657-3500, or call USD at (510) 477-7621.

Wastewater treatment plants like Union Sanitary District's are designed to handle normal household wastes. Pharmaceuticals flushed into the sewer system can pass into San Francisco Bay, where they may have an impact on fish and wildlife. Union Sanitary District will pay for the medicines to be hauled away from safe disposal drop-off locations and incinerated.

Cough medicines, creams and other liquids can be disposed of in their original containers. Remove pills from medicine bottles before disposal and black out personal information before placing empty containers in your recycle bin.
