UNSPSC 78131808: Bulk liquid storage tanks construction and maintenance

Construction and maintenance of bulk liquid storage tanks. According to the tank construction code, tanks must be inspected periodically for corrosion and other damage. Inspection and maintenance of steel aboveground storage tanks used in the petroleum and chemical industries, as well as cleaning, repairing, altering, and reconstructing them.

UNSPSC 78131808 Bulk liquid storage tanks construction and maintenance (Commodity) encompasses the design, installation, restoration, rehabilitation, and replacement of large-capacity storage tanks for potable water, wastewater, industrial liquids, and specialized applications, along with associated infrastructure work such as piping, pump stations, control systems, and tank interior/exterior protective coatings. State and local buyers—principally water utilities, city public works departments, county solid waste and utilities operations, and state environmental agencies—solicit this work regularly through competitive sealed bids (ITB), requests for proposals (RFP), and requests for quotations (RFQ). Recent opportunities show scope ranging from specialized coating restoration and minor structural repair of existing tanks to full tank replacement, new construction, demolition of obsolete assets, and integration with treatment systems and SCADA controls. Issuing bodies include municipal water utilities (City of Huntsville, Texas; City of Marietta, Georgia; Pinellas County, Florida; Unified Government of Athens-Clarke County), county infrastructure departments (DeKalb County, Georgia), state environmental services (Maryland Environmental Service; Texas General Land Office), and state transportation agencies (Texas Department of Transportation). Many procurements require mandatory site visits, pre-bid meetings, and compliance with specialized coating standards (SSPC blast preparation, epoxy systems, NSF potable water contact), tank material specifications (polyethylene, prestressed concrete, steel, crosslinked polyethylene), and performance bonds.

Recent activity concentrates in Texas, Georgia, and Florida. Representative opportunities include the City of Huntsville, Texas ITB for restoration and recoating of a half-million-gallon welded steel potable water storage tank (Bid 26-28, due July 14, 2026) specifying Tnemec brand coatings, three-coat zinc-rich epoxy systems to SSPC standards, interior safety ladder installation, and ninety-day contract completion with $1,500 per-day liquidated damages; the Pinellas County, Florida ITB for replacement of a 12,150-gallon single-wall microfiltration feed tank with crosslinked polyethylene construction and integrally molded flanged outlet technology (ITB 260374, due April 30, 2026, estimated value approximately $103,722); the City of Marietta, Georgia sealed-bid procurement for design and installation of a new five-million-gallon prestressed concrete tank with piping, valves, SCADA, electrical service, and complete demolition of an existing 4.3-million-gallon steel tank (due February 24, 2026); the Unified Government of Athens-Clarke County RFP for replacement of controls and pumps at the Northwest Booster Pump Station including Grundfos HydroMPC Skid installation, estimated $300,000 to $400,000 (RFP #26043, due July 2, 2026); and the Texas General Land Office RFP for bilge facility removal and replacement at Cove Harbor in Rockport, involving demolition of three tanks (6,502 and two 10,000-gallon units) and replacement with high-density polyethylene tanks, stainless steel pumps, and new building, 180-day completion window, with 0.50 percent veteran subcontracting goal and evaluation weighting 40 percent cost, 30 percent experience, 20 percent methodology, and 10 percent safety (due June 3, 2026). The Maryland Environmental Service competitive sealed-bid for New Germany State Park water and wastewater treatment plant, storage tank, distribution and collection system construction (750-day term, 8 percent MBE participation goal, due April 10, 2026) also falls within the code scope despite broader infrastructure focus.
