Keep catch basins/storm drains free of debris. Do not put anything into a catch basin that may clog the sewer system or pollute waterways, such as grass clippings, leaves, motor oil, concrete, paint, bottles or cans. Clogs in the sewer system can result in street flooding and water backing up into basements.

Lessen the potential of basement flooding by not pouring grease or other clogging substances into sinks or toilets. Properly dispose of cooking grease by placing it in a throw-away container. Do not place small objects where they may fall into toilets or sink drains, and only flush toilet paper. Take motor oil and paint to a recycling center.
