YELL 310402 Grant Wastewater Treatment Plant and Collections and Canyon Collect

The National Park Service (NPS) is seeking construction services for the Grant Wastewater Treatment Plant and Collections and Canyon Collections project at Yellowstone National Park, Wyoming. This procurement involves comprehensive wastewater infrastructure work including the construction of new facilities such as site civil infrastructure, headworks, process facilities, bioreactors, digesters, pump stations, generator and storage buildings, and underground storage tanks, as well as rehabilitation of existing infrastructure and installation of telemetry systems. The contract will utilize an unrestricted Full and Open contracting method under NAICS Code 237110 (Water and Sewer Line and Related Structures Construction) with a size standard of $45.0 million. The solicitation is scheduled to be issued electronically on SAM.gov on or about October 1, 2025, with proposals due by December 18, 2025. A mandatory pre-proposal meeting is scheduled for October 20, 2025, at Grant Village to provide additional project details to potential contractors.

This procurement does not include any set-aside designations and will be conducted as a full and open competition, though the NPS encourages participation from small businesses, veteran-owned small businesses, small disadvantaged businesses, and women-owned small business concerns as both prime contractors and subcontractors. The estimated contract value exceeds $10 million, reflecting the substantial scope of this wastewater treatment infrastructure project. The performance period is established at 975 calendar days, providing contractors with approximately two years and eight months to complete the construction work. No current incumbent contractors or potential successors are identified in the pre-solicitation notice, indicating this may be a new or significantly restructured procurement effort for the Yellowstone National Park wastewater treatment facilities.
