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 drain near you that need to be marked. 

Please note that storm drain marking is usually put on hold from December to March due to cold weather. For more details, check out our Storm Drain Marking Program information sheet. To get involved please fill out the Volunteer Waiver Form and contact Shannon Philbin
