Potable and Reclaimed Water Tank Inspection

The Department of the Interior National Park Service Intermountain Region has issued a Request for Quotation (RFQ) for comprehensive potable and reclaimed water tank inspections at Grand Canyon National Park. The solicitation (140P1525R0020) requires interior and exterior inspections of 14 water tanks with volumes ranging from 15,000 to 3,000,000 gallons located throughout the park. Contractors must conduct detailed structural integrity assessments, coating condition evaluations, safety feature inspections, and overall code compliance reviews, producing comprehensive inspection reports with maintenance recommendations. The contract will be awarded as a firm-fixed price commercial arrangement under NAICS code 221310 with a small business size standard of $41 million. Quotes are due by August 28, 2025 at 5:00 PM ET, and contractors must be registered in the System for Award Management (SAM) with a valid Unique Entity Identifier (UEI).

This opportunity is designated as a 100% small business set-aside, restricting participation to qualified small business concerns. The inspection work must be completed between September 2, 2025 and November 29, 2025, providing contractors with approximately three months to perform the required assessments. The contract involves inspecting a significant number of water storage facilities with substantial combined capacity, as the 14 tanks range from smaller 15,000-gallon units to large 3,000,000-gallon installations. All work will be performed at various locations throughout Grand Canyon National Park in Arizona. The solicitation does not identify any incumbent contractors or provide specific budget ranges, though the firm-fixed price structure indicates the government expects definitive pricing from qualified offerors.
