Recent Improvements

In 1994, as part of a research project to determine if wetlands could polish effluent from the 91st Avenue Wastewater Treatment Plant so it could meet upcoming wastewater treatment regulations, the city, in cooperation with SROG and the U.S. Bureau of Reclamation, created the Tres Rios Constructed Wetlands Demonstration Project. Another goal of the project was to restore the natural wildlife environment of the Salt River in that area. Because of the success achieved with the demonstration wetlands, a full scale wetlands has been designed and has begun the initial phases of construction.

In 1991, the Lake Pleasant area was chosen as a possible location for a future plant that would make use of CAP water. The plant being located far to the north of town would allow for a finished water supply to be delivered mostly through gravity, thus reducing electrical pumping costs. The Lake Pleasant plant will go online in 2007.
