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. Take motor oil and paint to a recycling center. Clogs in the sewer system can result in street flooding. 

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, sink, or drains, and only flush toilet paper.

Always throw wipes in the trash, even those labeled "flushable". Keep a trash bin in the bathroom for easy disposal of wipes and other non-flushable items.
