NIGP 88544: Corrosion, Scale, and Sludge Control Chemicals: Alum, Amines (Morpholine, etc.), Sodium Sulfite, etc.

NIGP 88544 Corrosion, Scale, and Sludge Control Chemicals — an Item code — encompasses chemicals used by water utilities and wastewater operators to manage hydrogen sulfide corrosion, odor, and scale buildup in treatment plants and collection systems. State and local governments procure these items as line-item inputs to routine treatment operations: aluminum sulfate solution, sodium bisulfite, magnesium hydroxide slurry, sodium hypochlorite, hydrofluosilicic acid, and related treatment compounds delivered on recurring, as-needed schedules. The code draws solicitations from municipal water and wastewater departments, county utilities, and special-purpose water authorities across a range of jurisdiction sizes. Most solicitations are structured as firm-fixed-price requirements contracts with line-item bidding, permitting vendors to quote on individual chemicals in which they specialize; contracts typically run 12 months with renewal options extending to five years total. NSF Standard 60 certification and American Water Works Association compliance are near-universal requirements. Delivery within 48 to 72 hours of order placement during business hours is the standard expectation, with F.O.B. destination pricing including all transportation and off-loading.

Recent activity spans Georgia, Texas, Florida, Maryland, California, and Connecticut, with particular concentration in the Southeast. Representative recent solicitations include the City of Cartersville Water Department seeking aluminum sulfate solution, sodium bisulfite, sodium hypochlorite, chlorine, liquid lime slurry, and hydrofluosilicic acid (IFB PE60899NONST2027000000086, bids due October 30, 2026), the City of Tallahassee soliciting magnesium hydroxide slurry for hydrogen sulfide and odor control across 114+ pump stations (IFB 06726CPW, bids due June 16, 2026), and the City of Griffin, Georgia requesting 16 treatment chemicals including sodium hydroxide, potassium permanganate, and activated carbon for fiscal year 2027 (IFB #26-008, due May 28, 2026). The City of Austin sought sodium bisulfite solution delivery to wastewater treatment plants (IFB 2200 BYS1051REBID, due June 9, 2026) with local-business evaluation discounts of 5 percent on bids up to $500,000. Macon Water Authority and Howard County, Maryland each issued bids for broad water and wastewater chemical suites, reflecting steady baseline procurement across mid-sized utilities. No high-value single awards or multi-year statewide blankets appear in current notices; activity remains fragmented across individual utility procurement cycles.
