Water pollution degrades surface waters, making them unsafe for drinking, fishing, swimming and other activities. As authorized by the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) permit program controls water pollution by regulating pipes or ditches that discharge pollutants into waters of the United States. The Village of Winnetka has banned coal tar and phosphorus fertilizer in efforts to prevent chemical pollution in stormwater runoff.
Water Quality Improvements
The NPDES permit program is responsible for significant improvements to our nation’s water quality. Individual homes that are connected to a municipal system, use a septic system or do not have a surface discharge do not need an NPDES permit; however, industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters.
