Stormwater & Watershed Services

 Washington County lies within the Chesapeake Bay Watershed, the largest estuary in the United States. The Chesapeake Bay Preservation Act requires the use of effective management of stormwater pollution. 

Storm drains connect directly to our local streams, creeks and rivers. Unlike the sanitary sewer from our homes and businesses, water flowing into the storm drains is not treated. This means trash, pet waste, motor oil detergents and other pollutants from yards, driveways and parking lots can pollute our local water bodies and degrade water quality, restrict recreational activities such as swimming and fishing and threaten wildlife and human health. Storm drains empty directly into rivers, lakes and streams. Please keep our waters clean!
