NIGP 19075: Recycled Bulk Chemicals and Solvents

NIGP 19075 Recycled Bulk Chemicals and Solvents, an Item code, encompasses specialty chemical polymers and treatment compounds that state and local water and wastewater utilities procure to manage solids processing, dewatering, and treatment workflows. The code captures ongoing purchases of polymeric additives and chemical aids used in municipal water resource management, particularly in treatment facilities where solids separation, thickening, and dewatering operations require performance-specified compounds. Issuing bodies under this code include county water authorities and regional utility departments responsible for wastewater and water treatment infrastructure.

Gwinnett County Board of Commissioners, serving the Atlanta metropolitan area, recently issued a competitive sealed bid (IFB) on July 1, 2026, for solids dewatering and thickening polymer on an annual contract for its Department of Water Resources, with bids due July 30, 2026. The polymer will be applied across three county facilities—Crooked Creek Water Reclamation Facility and F. Wayne Hill Water Resources Center—where it will support belt filter press dewatering, rotary drum thickener operations, and centrifuge dewatering of multiple sludge streams. Award criteria emphasize total cost per dry ton of sludge processed and polymer effectiveness against minimum performance specifications, with a four-year initial term beginning October 19, 2026, and four optional one-year renewals. Suppliers not pre-approved on Gwinnett County's roster must complete mandatory bench-scale and full-scale performance testing by July 22, 2026, with the pre-approved product identified as Polydyne Clarifloc SE-1748. Contractors must furnish general liability ($2 million aggregate) and automobile liability ($1 million combined single limit) coverage, maintain lab samples, and provide certificates of analysis with each shipment verifying total solids, active solids, and viscosity.
