UNSPSC 40161704: Hydro cyclones

Hydro cyclone is a unit for solid separations from fluids

UNSPSC 40161704 Hydro cyclones is a Commodity code capturing equipment and installation services for water and wastewater treatment plant clarification systems. State and local governments buy primary and secondary clarifier mechanisms, drive systems, component rebuilds, replacement parts, and related controls and instrumentation under this code. Recent solicitations show clarifier procurement activity spanning full equipment replacement (new clarifier mechanisms with scraper arms, weirs, and hydraulic systems), drive unit replacement and rebuild services, and ancillary components such as particle counters and instrumentation. The issuing bodies are municipal utilities and county water departments with ongoing treatment plant modernization or post-disaster infrastructure recovery; Collier County in Florida, Seminole County in Florida, the City of Charlotte in North Carolina, Gwinnett County in Georgia, the City of Douglas in Georgia, and the City of Pendleton in Oregon have posted opportunities under or adjacent to this code within the past three months.

Geographic activity concentrates in Florida and Georgia, with secondary representation from North Carolina and Oregon. Representative recent opportunities include Collier County's sealed-bid project for SCRWTP Lime Softening Improvements—Blend Tank (due July 15, 2026, ITB, $3.29 million anticipated budget) combining new concrete blend-tank construction with chemical injection piping, analyzers, and instrumentation; the City of Charlotte's Invitation to Bid for McDowell Creek WRRF Primary Clarifier No. 4 Equipment (due April 8, 2026, ITB, 316L stainless steel 70-foot diameter mechanism with scraper arms and hydraulic feedwell, limited to four named manufacturers: Envirodyne, WesTech, Ovivo/Eimco, and Evoqua); Gwinnett County's replacement of particle counters at Lanier and Shoal Creek Filter Plants (due May 8, 2026, sealed-bid, Chemtrac PC3400 units or approved equivalents); and the City of Douglas, Georgia's clarifier drive removal, rebuild, and reinstallation (due March 10, 2026, sealed-bid, Evoqua H40 system). Hillsborough County, Florida has posted a five-year sole-source maintenance and parts contract with DXP Enterprises, Inc. ($6.6 million estimated) covering OEM equipment across twelve manufacturers including WesTech, Flowserve, Wilo, and Val-Matic. Work typically requires operating-facility constraints, prequalification or manufacturer approval, federal prevailing wage and disadvantaged business enterprise compliance where grant-funded, and performance bonds.
