The project involves completely replacing an existing 14.5 million gallon underground water storage tank built in 1904, including partial demolition of the existing structure while maintaining continuous water treatment plant operations. Key requirements include constructing a new reinforced concrete watertight tank, reconstructing two historic building structures to preservation standards, installing baffle walls, access hatches, drainage chambers, and chemical dosing equipment. The procurement falls under NAICS code 237110 for Water and Sewer Line and Related Structures Construction. An Industry Day event was scheduled for July 30, 2025, at the Fallon Building in Baltimore, with registration required by July 28, 2025, and the full solicitation is expected to be published around May 2025 with responses due by July 30, 2025.
This procurement does not utilize any set-aside designations and is open to all qualified contractors. No incumbent contractors are identified in the available documentation. The project carries an anticipated construction value between $25 million and $50 million, which aligns with the small business size standard of $45 million for this NAICS code. The construction duration is estimated at 36 months from the Notice to Proceed, expected to begin around November 2025. The existing clearwell structure measures approximately 612 feet long by 162 feet wide and must be replaced within its current footprint while maintaining the facility's operational requirements.

On 02 June 2025, the Principal Director of the Defense Pricing, Contracting, and Acquisition Policy rescinded Class Deviation 2025-O0002 and its Revision 1 which removed the mandatory requirement to include Project Labor Agreements in all large-scale construction projects greater than $35M.
