Tres Rios Wetlands Restoration
Submitted by Archer Western Contractors
This project was designed as a way to restore the region’s natural wetlands and further treat discharge from a nearby treatment plant. It eliminates the need for expensive supplemental treatment, saving taxpayers up to $300 million.
480 acres of emergent wetlands were constructed, plus public areas like multi-use trails, picnic areas and an environmental education visitor center. As the largest man-made wetlands in the world, this project offers a living research platform for research on natural water treatment.
100,000 aquatic plants and over 700 riparian trees and shrubs were planted to support fish and waterfowl. Crews installed a large temporary irrigation system, retention ponds and two large mobile pumps to get the plants established.
