Treatment Committee

Welcome to the OWWA Treatment Committee page

What We Do

The Treatment Committee takes the lead in addressing water quality issues and regulations from source to tap, and does so in cooperation with the OWWA Distribution and Source Water Protection Committees.

Our focus is on gathering and disseminating information related to achieving the highest quality water through treatment for all municipal purposes. We encourage, monitor, and report on applied treatment research by utilities, universities, and funding agencies.
