Stormwater runoff is generated when precipitation from rain and snowmelt events flows over land or impervious surfaces and does not percolate into the ground. As the runoff flows over the land or impervious surfaces (paved streets, parking lots, and building rooftops), it accumulates debris, chemicals, sediment or other pollutants that could adversely affect water quality if the runoff is discharged untreated.

Stormwater drains directly into drainage ditches and ultimately to area streams, rivers, and lakes. The systems serves to carry rainwater off urban streets, parking lots, construction sites, neighborhoods, and agricultural lands. As the water runs off these surfaces, various pollutants including oils, dirt, pesticide, herbicide, and fertilizer are carried into our storm drains.
