The City of Austin storm drain marking program is a hands-on project for volunteers who are interested in educating the public about pollution prevention.

To help prevent dumping in storm drains, volunteers place markers on the drains as a visual reminder that the storm drains run directly to our creeks. Volunteers can also distribute door hangers in the area to remind citizens that rain washes garden chemicals, pet waste, motor oil, and other pollutants from our yards, driveways, sidewalks, and all areas of land into our waterways.

Checking out storm drain marking kits is temporarily suspended due to COVID-19. This webpage will be updated when the program is reopened.

Participants must be available to come to our office between the hours of Monday, Tuesday, Friday 9:00 am - 4:45 pm or Wednesday, Thursday 1:00 pm - 4:45 pm for both a short, pre-activity training (by appointment) and to return the supplies upon completion. Participants have up to one month to mark storm drains when it is convenient for their schedule!

Each kit (good for 1-4 people) includes 25 storm drain markers. We can customize your kit. Let us know if you’d like fewer or more markers (up to a maximum of 50 markers per individual and 200 markers per group).

To volunteer to mark storm drains, contact the program coordinator.
