UNSPSC 40161704: Hydro cyclones

Hydro cyclone is a unit for solid separations from fluids

UNSPSC 40161704 Hydro cyclones (Commodity) describes equipment and services for water treatment and wastewater facility operations, though recent solicitations show the code is being applied to a wider range of clarifier and treatment-system mechanical work than the narrow code name suggests. State and local governments soliciting under this code are purchasing mechanical rehabilitation, replacement, and improvement work on secondary clarifiers, gravity thickeners, blend tanks, and aeration systems at municipal water reclamation and treatment facilities. Representative work includes drive-shaft replacement at treatment plants, secondary clarifier mechanism rebuilds, chemical injection systems, and proprietary aeration equipment. Issuing bodies are primarily water utilities and county water authorities—the City of Holly Hill and Collier County in Florida, Cobb County and the City of Rome in Georgia, Hillsborough County in Florida, the Macon Water Authority in Georgia, Great Lakes Water Authority in Michigan, Seminole County in Florida, the City of Pendleton in Oregon, and independent water reclamation and treatment authorities. Most recent activity clusters in the Southeast, particularly Florida and Georgia, with secondary clarifier rehabilitation and facility improvements dominating the posted solicitations.

Recent opportunities reflect active capital-project spending on treatment-plant modernization and hurricane-recovery repairs. Collier County posted Bid No. 26-8683R for South County Regional Water Treatment Plant lime softening improvements and blend tank construction at $4.27 million due September 21, 2026, with a mandatory pre-bid meeting on September 3, 2026. The Macon Water Authority issued an ITB for rebuild of gravity thickeners and clarifier #6 at Rocky Creek WRF at October 20, 2026, with a mandatory pre-bid meeting on October 6, 2026. Cobb County, Georgia solicited rehabilitation of secondary clarifiers at South Cobb Water Reclamation Facility with bids due August 27, 2026. The City of Pendleton, Oregon issued an IFB for West Secondary Clarifier rehabilitation under the 2025 Improvements Project, bids due June 25, 2026, with prequalification required and federal Davis-Bacon Act prevailing wage and Clean Water State Revolving Fund compliance mandated. Hillsborough County issued a sole-source notice for Wet Well Wizard aeration systems installation and five-year maintenance at $5.371 million over 2027–2032. Several solicitations note hurricane-recovery funding eligibility or active state grants, signaling sustained capital availability through 2027–2029.
