Replace wastewater treatment plant at dry tortugas national park

The Department of the Interior National Park Service Southeast Region is seeking contractors to replace the existing wastewater treatment plant at Dry Tortugas National Park, located 70 miles west of Key West, Florida. This construction project involves replacing the current Up flow Sludge Blanket Filtration (USBF) package treatment plant with a new Synthetic Media Trickling Biofilter type treatment plant. The contract will be structured as a firm fixed-price construction project under NAICS Code 237110 (Water and Sewer Line and Related Structures Construction). The full solicitation and bid documents are scheduled to be posted on SAM.gov on or about July 11, 2025, with a submission deadline of August 11, 2025. Contractors must be registered in the System for Award Management (SAM) to be eligible for award and must submit organization representations and certifications prior to submitting an offer.

This procurement opportunity is set aside exclusively for Service-Disabled Veteran-Owned Small Businesses, with the standard business size threshold established at $45.0 million. No incumbent contractors or current service providers are identified in the pre-solicitation documentation. While specific contract values are not disclosed in this pre-solicitation phase, the project scope indicates a substantial infrastructure replacement effort given the remote location and specialized nature of the wastewater treatment facility. The National Park Service strongly advises all prospective contractors to attend a mandatory site visit, with the specific date and time to be detailed in the full solicitation when released. Questions regarding this project should be directed to william_vazquez@nps.gov for clarification and additional information.
