Contact Tres Rios Environmental Restoration project staff

The Tres Rios Environmental Restoration project involves the rehabilitation of nearly 700 acres in and around the Salt River. This project seeks to restore a vital wetland and riparian habitat. The project creates a mutual relationship between the renewed wetlands and the nearby wastewater treatment plant.

The lush and scenic Tres Rios is now home to more than 150 different species of birds and animals. They include muskrats, raccoons, skunks, coyotes, bobcats, and beavers. Beautiful cottonwood groves, willows, mesquites, and other desert shrubs attract many migratory and wintering songbirds. This project is bringing the Salt River back to the condition it was in during the early 1800s. This project is repairing a natural habitat.

The reclaimed water from the wastewater treatment plant is pumped over to the wetlands. The plants and animals take what they need before it is discharged back into the river.
