UNSPSC 47101616: Sludge reducing agent

A substance added to reduce the amount of sludge generated by controlling the microbial metabolism in biological treatment processes such as sewage and wastewater

UNSPSC 47101616 Sludge reducing agent is a Commodity code covering chemical products that state and local water and wastewater utilities purchase for treatment and process control operations. Recent solicitations show this code encompasses a broad range of water treatment chemicals used across municipal water systems, wastewater treatment plants, and reclamation facilities—including sludge-dewatering polymers, corrosion inhibitors, chlorine-reduction agents, and related process chemicals. The buying base spans municipal water departments, county water authorities, and regional wastewater treatment operators across multiple states. Water utilities use the code to procure chemicals meeting NSF/ANSI standards for drinking water and wastewater treatment, with emphasis on product certification, delivery within defined timeframes (typically 48 hours to 15 days of order), and compliance with EPA and state regulatory requirements. Issuing bodies include city water services departments (Phoenix, Austin, Meriden, Griffin, Flowery Branch, Temple), county water resources divisions (Volusia, Hillsborough, Gwinnett), and independent water authorities (Tallahassee, Lubbock).

Geographic activity concentrates in Texas (Austin, Temple, Lubbock), Florida (Tallahassee, Volusia County, Hillsborough County, Meriden in Connecticut), and Georgia (Griffin, Flowery Branch, Gwinnett County), with additional recent opportunities from Arizona (Phoenix). Recent representative procurements include the City of Austin Water and Wastewater Services Department issuing IFB 2200 BYS1051 (rebid as of May 11, 2026) for sodium bisulfite solution delivery to wastewater treatment plants with a June 9, 2026 response deadline; the City of Tallahassee requesting sealed bids (IFB-067-26-CPW, due June 16, 2026) for magnesium hydroxide slurry supply across a five-year initial term with optional two-year extensions; the City of Lubbock issuing ITB 26-19332-YB (January 28, 2026) for liquid polymer sludge-handling chemicals with one-year initial term and two optional one-year renewals; and the City of Flowery Branch posting IFB 26-007 (April 21, 2026 response date) for a five-year wastewater and drinking water treatment chemical supply contract covering aluminum chlorohydrate, sodium hypochlorite, sodium hydroxide, citric acid, hydrofluosilicic acid, and polymer products. Contracts typically run one to five years with optional renewal periods, firm-fixed pricing for initial terms, and delivery performance expectations tied to operational demand rather than guaranteed minimum volumes.
