UNSPSC 40151552: Metering or injection or proportioning pumps

UNSPSC 40151552 Metering or injection or proportioning pumps (Commodity) covers chemical feed equipment and replacement parts for water and wastewater treatment systems, including lime slaking systems, polymer feed metering pumps, and specialized injection systems for chlorine, caustic, and corrosion inhibitor applications. State and local procurement under this code centers on proprietary OEM replacement parts, authorized maintenance and service for existing treatment infrastructure, and new chemical injection and metering equipment tied to specific facility upgrades. Issuing bodies include city water departments and wastewater authorities, county water treatment operators, and regional water reclamation facilities. Recent solicitations reveal a heavy reliance on sole-source and single-source determinations, driven by equipment compatibility and the proprietary nature of installed systems; competitive opportunities emerge primarily when municipalities conduct broader facility improvements or retrofit projects involving multiple pump types and ancillary equipment.

Recent activity concentrates in Florida, Georgia, and Arizona, with secondary activity in Texas and Mississippi. Representative opportunities include the City of Holly Hill, Florida's sole-source procurement (26PWSS10) for Chemco Systems lime slaking replacement parts and maintenance, issued October 19, 2026; the City of Phoenix Water Services' five-year pump supply IFB (IFB-26-0287) for Aurora, Jacuzzi, and Stranco pumps with parts and repair services, solicited May 2026 with contract commencement August 1, 2026; Collier County's construction bid (26-8683R) for South County Regional Water Treatment Plant lime softening improvements with blend tank and chemical injection systems, due September 21, 2026 for $4.27 million; and the City of Atlanta Department of Watershed Management's multi-step sealed bid process for pump repair, maintenance, and parts services across nine pump classifications, with a May 2026 pre-advertisement notice. Sole-source and single-source notices dominate the recent opportunity landscape, reflecting the installed-base dynamics of treatment infrastructure procurement and limiting open competition primarily to facility expansions or major equipment transitions where multiple vendors can bid.
