UNSPSC 40151552: Metering or injection or proportioning pumps

UNSPSC 40151552 Metering or injection or proportioning pumps, a Commodity code, encompasses chemical injection and metering equipment that state and local water utilities procure to support treatment operations — specifically chemical dosing systems for chlorination, caustic feed, ammonia injection, corrosion inhibitor application, and polymer blending across drinking water and wastewater treatment facilities. Issuing bodies include water authorities, municipal water departments, county utilities, and state procurement offices. The work solicited ranges from supply of new equipment and OEM-certified replacement parts to full-service repair, rebuild, and maintenance support for proprietary systems already installed at treatment plants. Water utilities typically require vendors to meet strict delivery timelines (parts within 24 to 72 hours), maintain manufacturer certifications, provide warranty coverage, and demonstrate capability to service equipment while facilities remain operational — often with limited shutdown windows and strict safety compliance.

Recent activity spans Florida, Georgia, Texas, Arizona, and California. The Jackson County Utility Authority (Mississippi) requested quotes for a chlorine booster station due July 15, 2026 (RFQ, BABA-funded). Collier County (Florida) issued a sealed bid for lime softening improvements including chemical injection systems for chlorine, caustic, ammonia, and corrosion inhibitor, with $3.29 million budget and substantial completion in 277 days (IFB, bid opening July 1, 2026). The City of Atlanta Department of Watershed Management posted two pre-advertisement notices — one for SNF Polydyne Floquip polymer blending units and OEM parts/repair services (IFB, due June 5, 2026) and another for nine pump classifications including repair and parts support (multi-step sealed bid with prequalification, due May 29, 2026). The City of Phoenix Water Services solicited pumps, parts, and repair services for Aurora, Jacuzzi, and Stranco equipment across multiple city departments on a five-year contract (IFB-26-0287, due May 6, 2026). The City of Holly Hill (Florida) issued a sole source notice to Chemco Systems L.P. for lime slaking systems and OEM parts. The State of California posted a brand-specific RFB for chemical metering pumps (RFB-IS-26200557, due February 4, 2026). These solicitations reflect sustained demand for both equipment supply and integrated maintenance/repair capabilities in water infrastructure.
