UNSPSC 95121804: Water tower

A structure above ground used to hold large volumes of water for eventual use

UNSPSC 95121804 Water tower (Commodity) identifies elevated and ground storage tanks, hydropneumatic vessels, and related water storage infrastructure installed or maintained under state and local water system capital projects. Recent state and local solicitations under this code show strong demand for tank construction, restoration, and associated mechanical and electrical systems serving municipal water systems, utility authorities, and educational institutions. Issuing bodies include water departments and utility authorities in mid-sized cities and counties, alongside state agencies and university systems. Representative recent solicitations include the City of Huntsville, Texas (Bid NO. 26-28) requesting sealed bids for interior and exterior recoating of a half-million-gallon welded steel potable water storage tank with a July 14, 2026 deadline under IFB; the City of Apopka, Florida (IFB 2026A308) soliciting construction of the Golden Gem Reclaimed Water Storage and Pumping Station with a cast-in-place concrete wet well and vertical turbine pumps, bids due June 30, 2026; and Springfield Utility Board (ITB 2026-14) requesting bids on construction of Willamette Heights Tank No. 4 with bids due August 4, 2026. Texas A&M University System (RFP TAMUSCSP013418C) is soliciting proposals for a composite elevated water storage tank and associated infrastructure at the RELLIS campus with proposals due July 14, 2026.

Geographic activity centers on Texas, Florida, and Georgia, with sporadic activity across the Southeast and Upper Midwest. The code shows consistent activity across water utility capital projects tied to system expansion, replacement, or rehabilitation. Work typically spans twelve to twenty weeks from notice to proceed through substantial completion and includes interior/exterior coating systems, structural repairs, mechanical equipment installation (blowers, pumps, controls), electrical and instrumentation systems, and site restoration. Bid security requirements of 5 to 10 percent and performance/payment bonds at 100 percent of contract value are standard. Contracts often enforce liquidated damages ($85 to $1,500 per day) for delays and require compliance with AWWA standards, potable water NSF 61 certification, and Build America, Buy America Act provisions when federally funded. Water system operations must continue during construction, limiting work hours and requiring coordination with plant staff to minimize disruption.
