Pollution Prevention (MS4)

Only Rain Down the Storm Drain!

Did you know that Flagstaff's storm drain system and sewer system are separate? What goes down the storm drain is not treated at a treatment plant, but flows untreated into the Rio de Flag. Help us protect our local waterways by preventing stormwater pollution. Hazardous Household Waste, including automobile oil, can be disposed of at the Flagstaff Hazardous Products Center (HPC).
