PARKER, CO — Garney, a national water and wastewater contractor with a regional office in Denver, Colorado, is leading the joint venture with Burns & McDonnell, which will serve as the design engineer for the North Water Reclamation Facility (NWRF) Phase 1B Expansion. This project will support Parker Water & Sanitation District’s (PWSD) long-term treatment capacity, performance, and reliability.
Parker, located within the greater Denver area, is among the fastest-growing communities in the region, with the town and surrounding areas seeing rapid population increases. In response to the growth, PWSD is expanding wastewater treatment capacity at the NWRF. Garney served as the construction manager-at-risk for Phase 1A, completed in 2022, and is now leading Phase 1B.
“Phase 1B continues the careful planning and technical progress we began in Phase 1A,” said Adam Theriault, Garney’s Design-Build Manager on the project. “This next phase will increase capacity and build on innovative treatment solutions that set this facility apart, not just for what it can handle today, but for how it’s positioned to serve the community for decades to come.”
Phase 1B includes new construction and upgrades to existing facilities, adding 2.8 million gallons per day (MGD) for a total capacity of 6.6 MGD. An alternatives analysis will inform the final scope, which may include upgrades to existing headworks facilities and expansion of the secondary treatment, advanced water treatment, and sludge treatment processes, including evaluation of additional autothermal thermophilic aerobic digestion (ATAD) units.
In Phase 1A, Garney upgraded the plant’s aerobic digesters to ATAD, enabling the production of Class A biosolids — a level of treatment not commonly found at wastewater facilities.
