NIGP 88528: Antifoaming Agents

NIGP 88528 Antifoaming Agents is an Item code that encompasses chemical additives and treatment compounds used in municipal water, reclaimed water, and wastewater treatment operations. State and local governments procure antifoaming agents alongside a broader array of water treatment chemicals—sodium hydroxide, hydrated lime, liquid chlorine, polymers, sodium hypochlorite, activated carbon, and similar compounds—as part of routine facility maintenance and operational supply contracts. Water treatment facilities, reclaimed-water systems, and wastewater treatment plants in cities, counties, and regional water authorities are the primary end users. Procurement typically occurs through line-item competitive bidding on annual or multi-year blanket supply agreements, with delivery required to multiple treatment facilities and pump stations throughout a jurisdiction. Specifications demand compliance with AWWA and ANSI/NSF standards; pricing is often evaluated on a per-chemical basis rather than as a bundled package, allowing vendors to bid selectively on the compounds they supply and giving municipalities flexibility to award individual line items to the lowest responsive and responsible bidders.

Recent activity shows municipal and county water systems in Georgia and Florida actively soliciting under this code. The City of Griffin, Georgia issued Invitation to Bid #26-008 in April 2026 for water treatment chemicals including antifoaming agents and related compounds for Fiscal Year 2027 (July 1, 2026 through June 30, 2027) with options for up to four one-year renewals, with responses due by May 28, 2026 through the Vendor Registry platform. Hillsborough County, Florida's Water Resources Department, while conducting a sole-source procurement with DXP Enterprises for proprietary equipment and maintenance services across water and wastewater facilities (estimated $6.6 million over five years), indicates parallel procurement of treatment chemicals and supplies as part of routine facility operations. Bidders should note that municipal water treatment chemical contracts typically require NSF 60 approval, CAS Registry Numbers, strict delivery windows (often 72 hours), and FOB pricing with no fuel surcharges; pricing firms for initial 12-month terms with increases permitted only upon renewal supported by U.S. Department of Labor indices documentation.
