NIGP 18036: Chlorine Carriers, Inorganic and Organic

NIGP 18036 Chlorine Carriers, Inorganic And Organic, an Item code, encompasses chemical treatment polymers and related compounds that state and local water and wastewater utilities procure for solids management and treatment processes. The Gwinnett County Board of Commissioners solicitation posted July 1, 2026 exemplifies the actual scope: a competitive sealed bid for solids dewatering and thickening polymers applied across three water reclamation and treatment facilities to manage sludge through belt filter press, rotary drum thickener, and centrifugation processes. State and local water resource departments and utilities are the primary issuing bodies under this code, purchasing polymers and chemical carriers as input materials for ongoing treatment operations rather than equipment or infrastructure.

Geographic activity appears concentrated in states with substantial municipal and county water systems. The Gwinnett County, Georgia solicitation—with a four-year contract term beginning October 19, 2026 and four optional one-year renewals—demonstrates the typical structure: annual or multi-year commitments tied to treatment facility cycles, with pricing firm for the initial term and indexed for renewal options. Bidders must complete mandatory bench-scale and full-scale performance testing by July 22, 2026, with sealed bids due July 30, 2026 at 2:50 p.m., and award going to the lowest responsive and responsible bidder based on total cost per dry ton of sludge dewatered and polymer effectiveness. Insurance requirements (general liability at $2 million aggregate, automobile liability at $1 million combined single limit, workers' compensation at Georgia statutory limits) and supply obligations—including certificates of analysis verifying total solids, active solids, and viscosity with each shipment—are standard for competitive bids in this category.
