Related Information
  • CWA-NPDES Permit Compliance Technical Assistance Webinar Series

There are more than 4,500 publicly owned discharging wastewater lagoon systems in the U.S. and these lagoons comprise approximately 24% of all publicly owned treatment works (POTWs). This webinar discusses:

  • how lagoon systems are designed to treat wastewater and common compliance problems operators face. 
  • several new tools EPA has developed for lagoon operators including the First Stop Toolbox for Lagoons, a Lagoon Troubleshooting Manual, and two documents providing compliance tips for lagoon operators.
