UNSPSC 31162818: Anti corrosion anode

An electrically charged device used in corrosion control systems to prevent corrosion of underground or underwater steel structures.

UNSPSC 31162818 Anti corrosion anode, a Commodity code, covers cathodic protection equipment and services that state and local water utilities and transit authorities procure to prevent corrosion in pipelines, water storage systems, and other infrastructure. Recent solicitations show demand for anode installation, replacement, system testing, troubleshooting, remote monitoring, and related rectifier and bonding work performed across geographically dispersed facility networks. Issuing bodies include state water agencies, county facility management departments, and transit authorities. The work typically requires specialized licensing (electrical, general engineering, or well-drilling credentials in the state of performance), multi-year field experience in cathodic protection systems, and in-state service shop locations. Contracts are commonly structured as time-and-materials arrangements with hourly labor rates, equipment charges, and materials at cost-plus markup, with mandatory pre-bid conferences and public bid openings. Set-asides and preferences vary by issuer—disabled veteran business enterprise commitments, small business preferences, and local vendor preferences appear in recent awards.

California dominates the recent activity. The California Department of Water Resources issued IFB #10215192 on May 18, 2026, for cathodic protection testing, installation, repair, and remote monitoring services across five State Water Project divisions (Oroville, Delta, San Luis, San Joaquin, and Southern Field Divisions), with bids due June 16, 2026 at 3:30 p.m. and a mandatory pre-bid conference on June 2, 2026; the contract runs three years with three optional one-year renewals and includes a mandatory 3.0% disabled veteran business enterprise participation floor. San Bernardino County Project & Facilities Management issued ITB 6391 on May 18, 2026, for parts and supplies supporting facility maintenance with a June 19, 2026 deadline; while the 500-line-item scope spans HVAC, electrical, plumbing, and chemicals, anode-related components may appear among the miscellaneous supplies listed. The Orange County Transportation Authority's IFB 250199 (posted May 1, 2026, due March 16, 2026) solicited threaded fasteners and related products over a three-year, $150,000 term; though primarily focused on bolts and hardware, fastening supplies support anode bed and cathodic system installation work. All three opportunities carry prevailing wage or Davis-Bacon requirements and specify North American or U.S. manufacturing preferences.
