UNSPSC 48101619: Water sterilization system

Equipment that makes the sterilized water for sterilization or washing the food materials, kitchenware, kitchen supplies and others.

UNSPSC 48101619 Water sterilization system (Commodity) covers proprietary replacement parts, chemical treatment programs, and maintenance services for water disinfection and treatment infrastructure at municipal facilities. State and local governments procure under this code to maintain or upgrade UV sterilization systems, water softening equipment, lime slaking systems, chilled water treatment infrastructure, and related OEM components when integrated into existing facility operations. The work typically involves sole-source or limited-competition acquisitions because water treatment equipment is often proprietary and specific to installed systems; replacement parts and authorized service are typically available only from original manufacturers or exclusive distributors to ensure compatibility and prevent contamination or permit violations.

Recent solicitations show activity concentrated in Florida and Georgia, with scattered activity in Texas and New Mexico. The City of Holly Hill, Florida has issued multiple sole-source notices for WesTech drive shaft replacement ($113,067, with equipment and turnkey installation), Xylem Flygt OEM parts, Chemco Systems lime slaking systems, and Andritz Separation equipment components; all cite proprietary design and integration with existing infrastructure as justification. Collier County, Florida posted an IFB for $4.27 million in lime softening and blend tank construction at the South County Regional Water Treatment Plant (bids due September 21, 2026), a related earlier iteration with $3.29 million budget, and a sole-source notice for Nalco chilled water treatment services through September 2030.
