The Truckee Meadows Water Authority (TMWA) announced on April 9, 2026, that it hired Carollo Engineers to provide construction management services for the Advanced Purified Water Facility (APWF), smartwatermagazine.com reported.
The $200 million project developed under the OneWater Nevada initiative will be Nevada's first large-scale water purification and reuse facility.
TMWA is collaborating with the city of Reno on the facility, which will be built a few miles north of Reno, smartwatermagazine.com reported.
The project is designed to play a key role in regional water resource management and aims to produce Category A+ Advanced Purified Water, as defined by the Nevada Administrative Code (NAC 445A). That standard produces water suitable for all reuse applications, including groundwater recharge.
"The Advanced Purified Water Facility represents a transformational investment in the Truckee Meadows' water future," said Lydia Teel, TMWA's water operations and emerging resources supervisor. "This innovative project demonstrates our commitment to diversifying our region's water portfolio while collaborating with our partners at the city of Reno to improve wastewater management."
Carollo duties will include overseeing construction management, including resident engineering, quality assurance and contract administration across multiple project sites, with support from DOWL, a professional services firm, according to smartwatermagazine.com.
The facility is being designed to treat secondary effluent from the Reno-Stead Water Reclamation Facility using a multi-barrier process based on ozone oxidation and biological filtration, according to smartwatermagazine.com.
Treatment processes will include ozone injection for advanced oxidation, which is followed by biologically active carbon filtration that removes remove dissolved organic matter. Final steps include granular activated carbon adsorption and ultraviolet (UV) disinfection, smartwatermag-azine.com reported.
Those ensure compliance with state and federal drinking water standards yet avoid brine concentrate streams typically associated with reverse osmosis systems.
After it is treated, the water will move for approximately 7 mi. through dedicated pipelines to a rural area. There it will support agricultural irrigation and aquifer recharge, smartwatermagazine.com reported.
The system will feature injection, monitoring and extraction wells that allow for aquifer storage and recovery, while offering a flexible reserve that's accessible during periods of high demand or drought.
In addition, the project includes upgrades to the Reno-Stead Water Reclamation Facility, export pump station construction, the installation of conveyance pipelines and the development of finished water storage tanks, smartwatermagazine.com reported.
Provisions were made for a future potable water pipeline that connects to the TMWA distribution network.
