About Us

The Clean Water Institute was created by Clean Water Services, a public water resources utility that is nationally-recognized for its pioneering advancements in treatment technology, environmental education, business process reengineering, resource recovery and regulatory compliance.

Clean Water Services is one of the nation's most respected public utilities due, in part, to its culture of innovation. Its technology and expertise are in high demand as a result. The Clean Water Institute was created to meet this demand, expanding the ability of Clean Water Services to make a positive global difference.

As a 501(c)3 nonprofit organization, the Clean Water Institute can access diverse forms of funding to advance the research, development and implementation of new treatment technologies; watershed recovery programs; and organizational management strategies.
