NIGP 11514: Catalysts, Biochemical

NIGP 11514 Catalysts, Biochemical (Item) covers emulsified polymers and similar treatment chemicals that state and local water utilities procure for sludge dewatering and solids processing at wastewater and water reclamation facilities. The work involves supplying specialized polymers formulated to achieve specific performance thresholds—such as cake solids and solids capture efficiency targets—for use in centrifuges, belt filter presses, and screw presses that process municipal biosolids. Issuing bodies under this code are primarily special districts and regional water authorities managing water and wastewater treatment infrastructure; the recent activity shows independent water districts and similar special-purpose authorities as the dominant buyers.

Tohopekaliga Water Authority (Toho), an independent special district serving portions of Osceola, Orange, and Polk counties in Florida, issued IFB-26-011 on February 23, 2026, for supply and delivery of emulsified polymer to support sludge dewatering operations across five water reclamation facilities, with a response deadline of March 26, 2026. The solicitation required mandatory preliminary bench testing at one facility (March 10–12, 2026) to validate that the polymer met minimum performance criteria of 18 percent cake solids and 84 percent solids capture efficiency. Vendors submitted pricing on a per-unit basis for both 275-gallon tote and 2,500-gallon tanker deliveries with FOB Destination terms, freight prepaid, and no fuel surcharges. The initial contract term ran from execution through March 31, 2029, with two optional one-year renewals and a possible 90-day unilateral extension. The award went to the lowest responsive and responsible bidder, with estimated monthly requirements ranging from two totes every 2–3 months to five totes per month across facilities, plus tanker deliveries to the primary site every 14–16 days.
