Protecting Public Health and the Environment by Providing a forum for Wastewater Technology Exchange and Education. 

Hundreds of millions of gallons of wastewater are generated by citizens and businesses in Wisconsin every day.  This wastewater must be collected, analyzed, and treated before it can be discharged to our lakes, rivers, and streams. Making certain these discharges do not harm the quality of Wisconsin's surface water and groundwater is a large and important task.  

One of WWOA's primary goals is to protect Wisconsin's water quality through effective and efficient operation of wastewater treatment facilities by trained professionals.

The WWOA is comprised of wastewater treatment professionals who serve municipalities and industries throughout the state of Wisconsin. Membership includes treatment plant operators, engineers, consultants, plant managers, equipment manufacturers, regulatory agencies, educators, and students involved in the wastewater treatment industry.
