UNSPSC 47101543: Surface aerator

A device used to provide air to aerated basins. Electrically powered rotors are submerged in the water to provide air to the water by stirring the water surface with rotation power.

UNSPSC 47101543 Surface aerator, a Commodity code, does not map cleanly to the recent state and local solicitations in the source. The posted opportunities span water treatment chemical supply, wastewater equipment replacement, bypass pumping services, polymer blending systems, bar screens, diffuser replacement, pump maintenance, SCADA upgrades, chlorine dioxide generation, pipe lining rehabilitation, and design-build water treatment plant improvements across Florida, Georgia, Texas, California, and Arizona. None of these solicitations explicitly reference surface aeration equipment or aerator systems. The code's nominal scope—aeration devices used to introduce air into water or wastewater for biological treatment, oxygen transfer, or mixing—does not align with the mix of work actually being procured under this code in the recent record.

The data shows robust activity in broader water and wastewater infrastructure procurement at regional water authorities, city water departments, county utilities, and special districts, but the specific category of surface aerators does not appear in either the recent competitive opportunities or sole source notices captured in this window. Bidders pursuing this code should verify current RFP activity through state and local procurement portals and expect low velocity in this Commodity category relative to broader water treatment equipment and services codes higher in the taxonomy.
