NIGP 88548: Descaling Compounds

NIGP 88548 Descaling Compounds, an Item code, covers water treatment chemicals that state and local water systems procure to manage scale buildup and support potable water delivery—specifically descaling agents, corrosion inhibitors, and related chemical compounds that condition water in treatment facilities and distribution infrastructure. Recent solicitations show that purchasing bodies buy these chemicals on a line-item basis with firm pricing for initial contract terms, often paired with renewal options and delivery requirements to multiple treatment locations within tight service windows. Issuing bodies include municipal water departments and utilities; the City of Griffin, Georgia's recent Invitation to Bid for water treatment chemicals on a 12-month term with up to four one-year renewal extensions exemplifies the typical purchasing pattern, where line-item award to lowest-responsive-and-responsible bidders supports flexibility in sourcing across a broad chemical portfolio.

The code sees activity concentrated in municipal water systems where treatment infrastructure is mature and year-round chemical demand is predictable. The City of Griffin's ITB, posted April 29, 2026 with responses due May 28, 2026, sought 16 different treatment compounds (including sodium hydroxide, hydrated lime, liquid chlorine, potassium permanganate, and polymers) all meeting AWWA and NSF 60/61 standards, delivered within 72 hours to six treatment facilities across the city. Pricing remained firm for the initial 12-month term with increases permitted only upon renewal supported by U.S. Department of Labor indices. The solicitation permitted bidders to quote on any or all line items, evaluated award candidates on service capability, product quality, prior performance, warranties, and delivery terms, and applied location-specific delivery constraints including pallet jack clearance specifications and tanker pumper requirements. No incumbent vendor names, budget ranges, set-asides, or bid-bond requirements were disclosed.
