Introduction to NPDES

What is NPDES and Why It Matters

The National Pollutant Discharge Elimination System (NPDES) is a permit program under the Clean Water Act that regulates the discharge of pollutants from point sources into surface waters such as rivers, lakes, and oceans. Administered by the U.S. Environmental Protection Agency (EPA), the program requires facilities — including industrial plants, municipal treatment centers, and construction sites — to follow strict discharge limits and monitoring practices.

Understanding NPDES violations and permit statuses is essential for municipalities, businesses, and environmental professionals to ensure compliance, protect local ecosystems, and plan for potential water quality impacts.

KETOS PRISM transforms complex regulatory data into digestible, visual insights — saving you time and helping you focus on what matters most: clean, safe, and sustainable water systems.
