Y--GRCA 257282 - Replace South Rim Wastewater Treatment Plant, Grand Canyon, AZ

The United States Department of the Interior is seeking input through a Sources Sought Notice (SSN) for replacing the South Rim Wastewater Treatment Plant at Grand Canyon National Park, AZ. This notice aims to gauge interest and qualifications from both large and small businesses to inform the acquisition strategy and determine if a small business set-aside is appropriate for the upcoming project. The anticipated project involves constructing a new 0.65 million gallons per day membrane bio-reactor wastewater treatment facility, along with supporting infrastructure and site improvements, with an estimated cost exceeding $100 million. Key considerations include access logistics, construction impacts on park visitors, and seasonal restrictions. The government plans to issue a Request for Proposals (RFP) in early 2026, leading to a Firm-Fixed-Price contract award. Interested contractors are invited to complete a questionnaire detailing their qualifications and experience relevant to this project by July 21, 2025. No proposals are being requested at this time, and responses will help shape the forthcoming solicitation process.

The National Park Service (NPS) Denver Service Center has issued a Pre-Solicitation Notice for Request for Proposal (RFP) 140P2025R0093 to replace the wastewater treatment plant at the South Rim Village in Grand Canyon National Park, Arizona. This full-and-open, firm-fixed-price construction project has an estimated magnitude exceeding $100,000,000 (with some conflicting text noting more than $10,000,000) and an anticipated performance period of 1,035 to 1,095 calendar days. The scope of work involves constructing a new 0.65 million gallons per day (MGD) Membrane Bio-Reactor wastewater treatment plant at the existing site. Tasks include site preparation, utility connections, electrical and instrumentation systems, administrative buildings, access road improvements, and the complete demolition of the existing infrastructure once the new facility is operational. Due to the park's active operations and sensitive natural/cultural environment, the contractor must minimize visitor impacts, implement protective site measures, and accommodate winter construction and seasonal shutdowns. The nearest lodging and suppliers are located 25 to 75 miles away. The solicitation is expected to be released on SAM.gov after August 1, 2026, under NAICS code 221320 (Sewage Treatment Facilities). An on-site/virtual pre-bid conference is scheduled at the South Rim for August 11, 2026. Evaluation will follow FAR Part 15 best-value trade-off procedures considering technical, past performance, and price factors. Contact points are Contracting Officer Tim Burger and Contract Specialist Kristin Tauber.
