NIGP 83033: Filters, Storage Tank

NIGP 83033 Filters, Storage Tank is an Item code under which state and local governments procure storage tank removal, repair, replacement, testing, inspection, coating, and treatment services across water utilities, transit authorities, municipalities, counties, and school districts. Recent solicitations reveal a concrete scope spanning underground and aboveground petroleum storage tank (UST/AST) maintenance and decommissioning; chemical storage tank supply and installation; elevated water storage tank rehabilitation; diesel fuel tank treatment and cleaning; and removal of fuel tanks at municipal facilities. The work encompasses tank integrity assessment, interior and exterior coating and corrosion control, media replacement and filter restoration, biocide treatment, hydrostatic and operability testing, decontamination, excavation, site restoration, and comprehensive tank closure reporting. Issuing bodies include county water agencies and fleet operators, municipal water departments and fire services, transit systems, intermediate school districts, and special-purpose water districts—a mix reflecting the capital-intensive and regulatory-intensive nature of tank infrastructure across governmental operations.

Geographic activity spans California, Florida, Texas, Michigan, Connecticut, North Carolina, and Georgia, with particularly dense recent solicitation activity in California and Florida.
