NIGP 26940: Electrolytic, Caloric, and Water Balance

NIGP 26940 Electrolytic, Caloric, And Water Balance, an Item code, covers chemical commodities for municipal water treatment and pollution control operations. State and local governments procure under this code primarily sodium bisulfite and similar treatment chemicals used in wastewater and drinking-water facilities. The City of Meriden's July 2026 IFB for sodium bisulfite supply to its Water Pollution Control Facility exemplifies the scope: municipalities issue competitive bids for chemical supply contracts that specify product quality standards, delivery schedules, and unit-cost pricing. Issuing bodies are predominantly municipal water and wastewater utilities; the code sees activity from city procurement offices managing treatment-facility operations.

The City of Meriden's solicitation (B027-15, due July 29, 2026) represents the most recent visible activity under the code. Connecticut municipalities lead the recent opportunity set.
