Carollo Engineers to manage construction of Nevada's first water purification and reuse facility. $200M facility to enhance regional water security and sustainability. Release Date: April 8, 2026 Conceptual architectural rendering of the Advanced Purified Water Facility. Image courtesy of Truckee Meadows Water Authority RENO, Nev., April 08, 2026 - Truckee Meadows Water Authority (TMWA) has selected Carollo Engineers to provide construction management services for the Advanced Purified Water Facility (APWF) Undertaken by OneWater Nevada, a regional collaboration led by the City of Reno and TMWA, the $200 million facility will be Nevada's first water purification and reuse project. The initiative represents a major investment in regional water resource optimization, conservation, and innovative treatment technology. To be located a few miles north of Reno, the APWF was identified as a critical component of the region's comprehensive water management strategy. TMWA and the City of Reno have committed substantial resources to this major initiative to produce Category A+ Advanced Purified Water, optimize aquifer storage and recovery, and provide a drought-proof supply for the region's growing population. "The Advanced Purified Water Facility represents a transformational investment in the Truckee Meadows' water future," said dr. 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's selection reflects the firm's extensive experience in advanced water treatment design, innovative reuse projects, and complex construction management. Supported by DOWL, Carollo will provide comprehensive construction management services including resident engineering, quality oversight, and contract administration across multiple project sites, supporting coordinated execution and timely delivery. "We are honored that TMWA has selected this team to lead construction management for the Advanced Purified Water Facility project," said Carollo Engineers vice president keith corcoran. "This groundbreaking project represents a significant milestone in long-term regional water sustainability and security. Our team is committed to delivering expert construction oversight to facilitate completion of this critical initiative." The facility will provide a local, drought-resistant water source while reducing reclaimed water discharge into flood-prone Swan Lake by up to two million gallons per day and improving discharge water quality. The project demonstrates the viability of Advanced Purified Water in non-coastal states, potentially enabling implementation at other Nevada water reclamation facilities. The APWF will utilize an innovative ozone-biological-carbon based treatment system to produce purified water meeting state and federal drinking water standards. This proven technology offers advantages over conventional approaches, including lower capital and operating costs, reduced energy requirements, and elimination of brine-concentrate discharge associated with reverse osmosis systems. High-quality effluent from the Reno-Stead Water Reclamation Facility will undergo advanced ozone oxidation and biological filtration at the APWF followed by final polishing using granular activated carbon filtration and ultraviolet light treatment to produce Category A+ Advanced Purified Water (A+). As defined by the Nevada Administrative Code (NAC) 445A, A+ water is suitable for all Nevada water recycling practices, including groundwater augmentation. This A+ water will be conveyed seven miles to a rural site for agricultural irrigation as well as injected into the aquifer for storage and future withdrawal as needed. The project involves comprehensive improvements at multiple locations, including upgrades to the Reno-Stead Water Reclamation Facility, construction of the new APWF, an export pump station, conveyance pipelines, finished water storage tanks, and injection, monitoring, and extraction wells. The project also includes a potable water pipeline for future connection to the TMWA water system. Construction is anticipated to break ground this summer and continue through November 2028.

Hawaii Water Service launches feasibility study for new Kapalua recycled water treatment plant. February 24, 2026 · 12:00 PM PST Hawaii Water Service is moving forward with a feasibility study for a decentralized wastewater treatment plant in Kapalua that would produce recycled water and give the community a drought-resistant supply of irrigation water. Hawaii Water has selected Carollo Engineering Inc. to conduct the feasibility study for the plant. Currently, wastewater in Kapalua travels through Hawaii Water's system and is treated at the County of Maui's Lahaina Wastewater Reclamation Facility. The study, expected to be complete in fall 2026, will identify and evaluate potential sites for the new plant in Kapalua. It will also analyze advanced technologies that could improve the efficiency and effectiveness of Hawaii Water's wastewater treatment, along with regulatory and land area requirements and operations and maintenance costs. "We're dedicated to enhancing the quality of life for our customers and communities. We do this by investing in and responsibly maintaining our system for water and wastewater services," said Geoff Fulks, General Manager of Hawaii Water. "This study will help us determine if this new plant is the next investment that we need to make to increase supply reliability for our Kapalua customers." Already on Maui, Hawaii Water operates a wastewater treatment plant in Pukalani producing recycled water. It was the first such plant in the State of Hawai[[ʻ]]i to use state-of-the-art flat plate membrane bio-reactor filtration technology, which treats 200,000 gallons of wastewater per day for reuse. Hawaii Water selected the flat plate membrane process because it has a very small footprint, is less costly to maintain, and produces water that can be reused without restriction, freeing up precious potable water supplies. "Severe drought conditions have limited our customers' use of water for irrigation, and we can expect droughts again in the future," Fulks said. "This study is about finding ways that we can continue to provide excellent value to our customers, increase water supply reliability, and be a responsible steward of our limited, natural resource."
