NIGP 89047: Mixing and Agitation Equipment

NIGP 89047 Mixing and Agitation Equipment, an Item code, encompasses replacement drive shafts, mixer parts, and components for water and wastewater treatment facilities' aeration and chemical blending systems. State and local governments under this code procure proprietary mixer assemblies, drive units with dual-motor systems, diffuser components, and related parts necessary to maintain treatment plant operations—frequently as sole-source or limited-competition procurements when facilities are engineered around specific manufacturer equipment. Issuing bodies include water and wastewater utilities within county and municipal jurisdictions, with multiple Florida county utilities appearing in recent activity: the City of Holly Hill, Collier County, Pinellas County, and Marion County utilities, along with the Georgia county system and California's statewide Department of Water Resources.

Recent solicitations center on Florida and California jurisdictions. The City of Holly Hill, Florida awarded a sole-source Notice of Intended Decision (SS202001) on September 22, 2020 (posted October 19, 2026) for a WesTech DS43 Dual Shaft Drive replacement unit valued at $113,067 including installation.
