The map is created for general information purpose and is built based on EPA’s Clean Watersheds Needs Survey (CWNS) 2022 results.
The color represents treatment level with blue representing secondary, green representing advanced (tertiary), and red represents primary or raw (you don’t really see them because almost every WRRF in the U.S. are at least secondary). You can zoom in and click on each facility to learn about their detailed information such as design flow, treatment level and if equipped with disinfection. You can also search for WRRFs closest to you, or look for WRRFs in the specific region using the locate and search function.
