UNSPSC 12161706: Neutral buffers

UNSPSC 12161706 Neutral buffers, a Commodity code, encompasses water treatment and pool maintenance chemicals that state and local governments procure for municipal water systems, wastewater facilities, and public aquatic venues. The work being solicited is overwhelmingly concrete—municipalities and counties are buying specific chemical products with precise concentration, purity, and certification requirements for potable water treatment, wastewater processing, pool operations, and facility maintenance. Recent solicitations show cities and counties sourcing calcium hypochlorite, sodium hypochlorite (bleach), caustic soda (sodium hydroxide), muriatic acid (hydrochloric acid), liquid chlorine, aluminum sulfate, sodium permanganate, soda ash, polymers, quicklime, and specialty compounds. All products must meet NSF/ANSI standards or AWWA specifications; many require U.S. manufacturing origin under Buy America compliance. Issuing bodies include municipal utilities departments (Meriden, Jackson, Griffin, Salem, St. Petersburg, Lubbock), county water and wastewater authorities (Sarasota, Hillsborough, Flowery Branch, Orlando), school districts (Pinellas County Schools), and county recreation departments (Greenville County parks and aquatics). The code sees activity across multiple states and regions, with recent opportunities concentrated in Florida (Sarasota, Hillsborough, Orlando, St. Petersburg, Pinellas County), Georgia (Griffin, Flowery Branch), South Carolina (Greenville County), Texas (Lubbock), Connecticut (Meriden), Oregon (Salem), and Mississippi (Jackson). A few solicitations cite specific incumbent suppliers or reference existing integrated systems.

Representative recent opportunities span multiple notice types and response timeframes. The City of Meriden, Connecticut issued ITB B026-55 for water treatment chemicals (calcium hypochlorite, caustic soda, aluminum sulfate, sodium permanganate, sodium fluoride, phosphate blend) due June 25, 2026, with one-year contract terms and Build America Buy America compliance requirements for chlorine and permanganate products. Sarasota County's Quick Quote (2026QQ704) for industrial muriatic acid at the Bee Ridge Water Reclamation Facility closed May 12, 2026, capped at $50,000 total procurement. Greenville County, South Carolina issued two separate RFPs for pool chemicals and maintenance services—RFP #26100 (due May 5, 2026) and RFP #26073 (due March 16, 2026)—each seeking single-source contractors for twelve county-owned pools with seven evaluation criteria weighted equally and firm pricing across potential five-year terms.
