UNSPSC 47101537: Sludge conditioning equipment

UNSPSC 47101537 Sludge conditioning equipment is a Commodity code that encompasses replacement parts, mechanical drives, polymer conditioning chemicals, and dewatering apparatus used in wastewater treatment biosolids processing. State and local governments buying under this code procure replacement drive shafts for treatment-plant softener and thickener equipment, conditioning and emulsion polymer chemicals for biosolids dewatering, gravity thickener and clarifier mechanisms and components, polymeric chains and appurtenances for treatment processes, and related wear items and consumables. The issuing bodies include municipal water and wastewater utilities, county environmental departments, regional wastewater authorities, and specialized treatment plant operators. Recent solicitations show activity from small cities managing single-plant operations through mid-sized regional authorities operating multiple facilities across counties.

Recent opportunities reflect a geographic mix centered in the Southeast and Mid-Atlantic regions, with activity in Florida, Georgia, and Maryland. The City of Holly Hill, Florida posted sole-source procurement for a WesTech DS43 Dual Shaft Drive replacement at its Water Treatment Plant (solicitation SS202001, due September 22, 2020, $113,067.00 total). The Maryland Department of the Environment solicited liquid emulsion polymer for biosolids dewatering at Dorsey Run AWWTP (solicitation 1272145, RFQ response due November 13, 2026). The Macon Water Authority in Georgia issued an IFB for rebuild of gravity thickeners and clarifiers at Rocky Creek WRF (solicitation PE33561NONST2027000000686, bids due October 20, 2026, mandatory pre-bid October 6, 2026; project involves lump-sum pricing with 51-percent self-performance requirement and 100-percent performance and payment bonds). Gwinnett County Department of Financial Services in Georgia requested quotations for 150 units of polymeric chain (IWQ 133561, due August 5, 2026). The Maryland Environmental Service posted two liquid sludge hauling contracts restricting award to small business vendors under Maryland's SBR program (solicitations 1262625 and 1262665, covering six and four facilities respectively, with base-year and four-year option pricing structures and per-gallon compensation). Activity is sparse but sustained, concentrated in municipal and regional authority utilities managing aging treatment infrastructure.
