NIGP 92974: Tanks: Mobile, Portable, Stationary, Storage, etc., Maintenance and Repair (Includes Relining)

NIGP 92974 Tanks: Mobile, Portable, Stationary, Storage, Etc., Maintenance and Repair (Includes Relining) is an Item code under which state and local governments buy tank cleaning, inspection, maintenance, repair, relining, and replacement services across municipal water systems, wastewater treatment plants, emergency management agencies, correctional facilities, and transportation authorities. Recent solicitations show work ranging from chemical tank cleaning and desludging at municipal utilities to aboveground storage tank maintenance at state facilities, specialized brine line cleaning at correctional institutions, and potable water tank restoration. Issuing bodies include county water/wastewater departments (Palm Beach County, Worcester County), state environmental and transportation agencies (Florida DEP, California CDCR, TxDOT, Caltrans), municipal utilities (City of Meriden, City of Huntsville, Unified Government of Athens-Clarke County), transit authorities (Kansas Turnpike Authority), and specialized facilities (St. Mary's County MetCom). The code attracts vendors with hazardous materials certification, confined space entry credentials, commercial diver qualifications, equipment-specific licensing, and demonstrated experience in large-volume tank operations; many solicitations carry prevailing wage and bonding requirements tied to project scope and value.

Geographic activity concentrates in California (multiple CDCR, Caltrans, and state agency solicitations), Florida (county and state environmental protection projects), Texas (municipal and state transportation facilities), Maryland (county utility districts), and across the upper Midwest and mid-Atlantic. Representative recent opportunities include Palm Beach County's IFB for chemical tank cleaning (H₂SO₄ and NaOH removal, bids due November 16, 2026), the California Department of Corrections' invitation for water tank cleaning, maintenance, and repair across 32 statewide locations with mandatory 25% small business participation (bids due September 9, 2026), the City of Huntsville's ITB for half-million-gallon ground storage tank restoration and recoating (bids due July 14, 2026), and the Kansas Turnpike Authority's invitation for lagoon desludging at the Towanda Service Area (bids due October 21, 2026).
