What Not to Flush

Just because something can be flushed down the toilet, does not mean it should be. Toilet paper is specifically designed to break down in water. Although paper towel, napkins, and facial tissue appear to be of the same material, they do not disintegrate in water the way toilet paper does. These items can create costly clogs for both your home and our pipes. 

Do not flush these items down the toilet:

Not only do clogs affect our pipes, but they can affect yours, potentially causing a basement backup and expensive phone call to your plumber. If wipes get stuck in your home lateral pipe, a clog could cost you thousands to fix. A lateral is a pipe that transports water used inside your home out to your city's sanitary sewer system in the street.

A clog like this at our Port Washington Road Pumping Station costs thousands of dollars to remove.

What Can I Not Pour Down My Drain?

Dispose of all fats, oils, and grease in the garbage. This includes butter, cooking oils, fry oil, oils and grease left from cooking meats and/or anything else that gels or solidifies at room temperature. While these will go down the drain or toilet when warm or with soap, but as they cool or mix with water they solidify in your pipes creating a clog that is very messy and difficult to remove.

Never pour or flush hard chemicals, paint, oil, pesticides, cement, plaster, medications, or more than the recommended amount of drain cleaner down your drains.


Milwaukee County Residents can drop them off at one of Milwaukee Metropolitan Sewerage District's Home Hazmat Collection sites. Learn more about what items you can drop off.
