UNSPSC 47101506: Corrosion control equipment

UNSPSC 47101506 Corrosion control equipment (Commodity) covers chemical products and services that state and local water utilities deploy to manage hydrogen sulfide corrosion, odor, and sulfide precipitation in wastewater and water treatment systems. Recent state and local opportunities show water departments soliciting both bulk treatment chemicals—magnesium hydroxide slurry, sodium bisulfite, hydrogen peroxide, and related compounds—and integrated chemical-service contracts where vendors supply, deliver, and sometimes apply corrosion inhibitors to pump stations, force mains, and treatment plants on regular or emergency schedules. Cities, counties, water authorities, and school districts are the primary issuing bodies. The City of Tallahassee (magnesium hydroxide slurry for hydrogen sulfide and corrosion control across 1,000 miles of sewer main and 114+ pump stations), City of Austin (sodium bisulfite solution delivery to wastewater plants), City of Orlando (hydrogen sulfide control service with chemical application at three lift stations), and Cartersville Water Department (water treatment chemicals including chlorine and liquid lime) appear as active buyers. Dallas Independent School District solicited water treatment services on a district-wide basis under an RFP with an SBE participation goal of 30 percent and up to 20 evaluation points for SBE compliance.

Geographic activity concentrates in Georgia, Texas, and Florida, with additional procurement in California (Department of Water Resources), Connecticut (City of Meriden), and other states. Representative recent opportunities include the City of Tallahassee IFB for magnesium hydroxide slurry (IFB-067-26-CPW, due June 16, 2026, five-year initial term with two-year renewal options); City of Austin IFB for sodium bisulfite solution delivery (IFB 2200 BYS1051REBID, due June 9, 2026, with 5% local-business evaluation discount up to $500,000); City of Orlando IFB for hydrogen sulfide control service at three lift stations (IFB260556, due September 9, 2026); City of Griffin ITB for 16 water treatment chemicals including sodium hydroxide, sodium hypochlorite, and potassium permanganate (ITB #26-008, due May 28, 2026, renewable for up to four one-year extensions); and Cartersville Water Department solicitation for treatment chemicals at two facilities including aluminum sulfate solution, chlorine, and sodium bisulfite (due October 30, 2026). The California Department of Water Resources issued two IFBs for comprehensive water treatment system services across pumping and power plants (IFB #10220465 and IFB 10214188), the latter requiring a mandatory pre-bid conference on May 26, 2026, at Byron, California and bids due June 9, 2026. Most water utility contracts enforce NSF Standard 60 certification, require delivery within 48 to 72 hours of order, and specify F.O.B. destination pricing with no fuel surcharges.
