Treatment Plant Upgrades for PFAS Reduction in Drinking Water Through CMAR Collaborative Delivery

The City of Calhoun is seeking qualified Construction Manager at Risk firms to deliver critical upgrades to two municipal water treatment plants—the 12.8 MGD Brittany Drive WTP and the 18 MGD Mauldin Road WTP—to address emerging PFAS regulations. The project requires the integration of microfiltration and ultrafiltration pretreatment systems alongside reverse osmosis membrane technology at both facilities to ensure compliance with EPA maximum contaminant levels. This initiative is designed to enhance drinking water safety by effectively removing PFAS contaminants, and the City will utilize the CMAR delivery method to foster collaboration, early contractor involvement, and cost-effective project execution. Proposals must be submitted through the designated portal at www.QuestCDN.com, with all documentation and technical requirements available for review there. The solicitation, identified as PE-76500-NONST-2026-000000023, was posted on June 29, 2026, and proposals are due by 3:00 PM on July 30, 2026. This procurement is categorized as a State and Local Government (SLED) action under the authority of the City of Calhoun, Georgia. All questions and communications should be directed to Andrea Everett at aeverett@calnet-ga.net, the primary point of contact. The work is to be performed at the two specified treatment plant locations in Georgia, and interested firms are expected to demonstrate proven experience in water treatment modernization, particularly with membrane and advanced filtration systems under CMAR delivery. The project represents a significant infrastructure investment to meet federal health standards and ensure long-term public water quality.
