Clearwater Recharge Basins
Visitors travel to the Central Avra Valley Storage and Recovery Project (CAVSARP) where Colorado River water is recharged through eleven constructed basins to blend with the native groundwater below. Guests also visit the pumping station, hydropneumatic tanks and the delivery pipeline.
Hayden-Udall Water Treatment Plant
Tour participants visit Tucson Water's primary water treatment facility, including the ozonation building, flocculation basins, filtration areas and chlorination facility. The plant also is the site of the Water Quality laboratory.
Reclaimed Water Treatment Plant
Visitors are taken through the process of recycling wastewater for reuse as irrigation water for parks, schoolyards, golf courses and other facilities. The tour includes the filtration, disinfection and pumping facilities involved in creating and distributing reclaimed water.
This multi-purpose facility treats backwash water from our filtering system at the Reclaimed Treatment Plant. The wetlands provide an area for wildlife and riparian restoration and visitors learn about ecology and water resource management. This facility is also designed for self-guided tours. Gates open approximately one hour before sunrise and close approximately one hour after sunset. A Sweetwater Wetlands Activity Book and Field Guide is also available upon request.
Tucson Airport Remediation Project (TARP)
This facility is designed to remove trichloroethylene (TCE) from an area of contaminated groundwater near the Tucson International Airport. Visitors learn about the air-stripping process used to remove this volatile compound.
