Inspect and clean potable water tank

The National Park Service Intermountain Region is seeking a contractor to inspect and clean a 50,000-gallon elevated potable water tank located at Walnut Canyon National Monument in Flagstaff, Arizona. The solicitation (140P1525Q0053) requires comprehensive tank inspection and cleaning services, including interior and exterior assessments using ROV or diver inspection methods, sediment removal, mil thickness and ultrasonic testing, and tank disinfection according to AWWA standards. Contractors must submit a detailed written report with photographs and demonstrate at least three years of experience in potable water tank inspection. The government will evaluate quotations based on price, technical capabilities, and prior experience, with the contract awarded to the most advantageous proposal. The response deadline is March 25, 2025, at 12:00 PM Mountain Time, with a performance period from April 14, 2025, to August 15, 2025.

The solicitation is a 100% small business set-aside under NAICS code 562998 with a small business size standard of $16.5M. The water tank is 22'6" in diameter with a 19'0" head range, situated in a forested environment with pine trees and surrounded by fencing and an access gate.

No specific incumbent contractor is mentioned in the documentation, and the precise award value is not explicitly stated. The project timeline spans approximately four months, with the primary objective of maintaining the potable water tank's integrity and ensuring its proper functioning for the National Park Service.
