Storm Drain Marking

Are you an elementary or middle school student who wants to give Rockville's streams and wetlands a helping hand? Help spread the word about water pollution prevention by signing up for our Storm Drain Marker Program. Student service learning hours are available. See our interactive map below to find storm drains near you that need to be marked.

Please note that storm drain markers should only be placed when temperatures are between 40 and 90 degrees Fahrenheit. The program is usually put on hold from December to March due to cold weather.
