Storm Water

Storm Water Runoff … occurs during rainfall events or snow melt, causing 1000s of gallons of storm water to enter the City of Marietta’s storm drain system.   The storm drain system is made up of catch basins, pipes, ditches, andcreek1 small streams in route to one of the following large streams:  Ohio River; Muskingum River; Duck Creek.

Along the way … the runoff has a potential of becoming polluted when passing over lawns, construction sites, and impervious areas such as streets, sidewalks, and parking lots.  When passing over these surfaces, storm water can become polluted from trash, leaked automotive fluids, pet waste, lawn debris, and soil.  And, since storm water is untreated, it has a potential to pass this pollution to our streams and rivers, where it can adversely affect aquatic life, and can potentially affect drinking water supplies.

The Solution …
