How to bid on replacing the South Rim Wastewater Treatment Plant for the National Park Service

What the National Park Service is buying

The National Park Service is planning to replace the South Rim Wastewater Treatment Plant located at Grand Canyon National Park in Arizona. This is an opportunity for construction firms to understand the scope of an upcoming project.

This notice is a Request for Information (RFI), which means the agency is gathering input and assessing interest from potential vendors. It is not a request for proposals or bids at this stage, but it is a chance to influence the final solicitation.

Key dates and what happens at the deadline

This RFI was published on July 20, 2026. The deadline for responses is November 02, 2026, at 4:00 PM ET. All responses must be submitted by this time.

After the deadline, the National Park Service will review the information received from vendors. This feedback helps the agency refine its requirements and develop the formal solicitation for the project, which will be released later under the new solicitation number 140P2026R0101.

Who this opportunity suits

This RFI is suitable for construction firms with experience in wastewater treatment plant construction, upgrades, or replacement projects. Companies specializing in environmental infrastructure or large-scale civil engineering projects would find this relevant.

Firms that have previously worked on projects within national parks or other sensitive environmental areas may have an advantage due to familiarity with specific regulations and logistical challenges.

Tips for preparing a competitive RFI response

Even though this is an RFI and not a formal bid, your response should be professional and thorough. Clearly articulate your firm's capabilities and relevant experience in wastewater treatment plant projects. Highlight any specific expertise that aligns with working in a national park setting.

Provide concise and clear answers to any specific questions posed in the RFI. If the RFI asks for feedback on potential challenges or innovative solutions, offer thoughtful insights. Your response can help shape the final solicitation, so make sure it reflects your company's strengths and understanding of such projects.
