Multiple events led the City of Phoenix to the development of a tertiary wetland treatment system at the 91st Avenue Waste Water Treatment Facility. Ron Elkins will give an overview of the history and events of the as-built project, as well as a review of the operation of the project, which has shown interesting results in many areas, such as water quality and habitat restoration.
