Sundog trunk main sewer phase C3 construction

Solicitation #2026-NIBCONST-559. Issued by Public Works. The City of Prescott, Arizona, is advancing its long-term wastewater infrastructure centralization initiative through the Sundog Trunk Main Sewer Phase C3 Project. This critical capital improvement project supports the consolidation of wastewater treatment operations from the Sundog Wastewater Treatment Plant to the more modern and expandable Airport Water Reclamation Facility. It addresses capacity limitations, mitigates risk of sanitary sewer overflows highlighted by 2023 storm events that led to an ADEQ consent order, lowers long-term operations and maintenance costs, and enhances overall system reliability for current and future growth. Strategic Importance This phase is part of a multi-year, phased program to consolidate Prescott’s wastewater system. It directly supports the 2023 Water and Wastewater Models Master Plan by increasing conveyance capacity, eliminating bottlenecks from undersized or failing pipes, and enabling the eventual decommissioning of the Sundog plant. Benefits include improved environmental protection, enhanced public health and safety, and cost savings through more efficient operations. Opportunity for Vendors This is a significant public works project with substantial construction value. It offers experienced contractors and subcontractors in sewer force main installation, lift station construction, directional drilling or open-cut methods, pipeline rehabilitation, and utility work in urban/historic corridors an excellent opportunity to partner with the City of Prescott on a high-impact community infrastructure upgrade.
