YELL 318713 Rehabilitate/Replace Old Faithful Wastewater Treatment Plant

The National Park Service is preparing to procure rehabilitation and replacement of the Old Faithful Wastewater Treatment Plant at Yellowstone National Park (YELL 318713), with a competitive Request for Proposals anticipated in Fall 2026 and a response deadline to the sources sought notice of October 2, 2026. The procurement is not set-aside and will award a single Firm-Fixed-Price contract to either large or small business.

Work is performed at Yellowstone National Park in Wyoming. The project scope encompasses collection system upgrades (CCTV inspection, pipe repairs and replacements, manhole rehabilitation, CIPP lining), construction of a new wastewater treatment plant facility (civil sitework, headworks/UV facility, final clarifier, generator facility, digester facility, dewatering facility with associated piping, instrumentation, process control systems, and standby generator), and rehabilitation of three lift stations (Lodge Lift Station, Inn Lift Station, and Raw Sewage Pump Station). Construction must be coordinated to minimize visitor impact while the park remains operational, with potential seasonal shutdowns and possible winter construction requirements.

The estimated project magnitude is between $50 million and $100 million base plus options. NAICS code 237110 (Water and Sewer Line and Related Structures Construction) applies, with a small business size standard of $45 million. Bid, Performance, and Payment Bonds are anticipated to be required.

Responses to the sources sought notice, due by noon Mountain Time on October 2, 2026, must include company information, UEI number, business classification status and certifications (including HUBZone, VOSB, SDVOSB, WOSB, EDWOSB, ISBEE), bonding capacity statement, and evidence of experience on projects of similar size, scope, and magnitude.
