NIGP 220: Controlling, Indicating, Measuring, Monitoring, and Recording Instruments and Supplies

NIGP 220 Controlling, Indicating, Measuring, Monitoring, and Recording Instruments and Supplies, a Class code, covers pressure gauges, flow meters, temperature and pressure transmitters, level sensors, atmospheric monitoring equipment, analyzers, and related instrumentation that state and local governments deploy across water and wastewater treatment, distribution, environmental monitoring, and facility operations. Recent solicitations show municipalities procuring Ashcroft pressure gauges for pump station operations, Siemens process instrumentation for SCADA systems, cyanide and TOC analyzers for water quality compliance, flow measuring devices, hazardous-gas detection sensors, and laboratory testing services—the full range of equipment needed to monitor and control critical infrastructure. Issuing bodies span water and wastewater utilities, county environmental and facilities divisions, cities, and special-purpose water authorities, with repeat buyers including Hillsborough County (Florida), the City of Phoenix, City of Tampa, and Tucson Water. The code sees activity across the continental United States, with recent opportunities posted by municipalities in Florida, Arizona, Texas, Connecticut, New Mexico, South Carolina, Georgia, and Kentucky.

Representative recent opportunities include Hillsborough County issuing an ITB for 200 Ashcroft pressure gauges (September 2026, response deadline September 21, 2026) for deployment across 700+ pump stations in water and wastewater operations; the City of Phoenix Water Services Department requesting sealed offers for pressure, temperature, and flow instrumentation on a five-year contract (sealed offers due August 18, 2026, commencing October 15, 2026); Tucson Water issuing an IFB for chemical-resistant PVC and CPVC piping and fittings for sodium hypochlorite disinfection systems (August 18, 2023 post, responses due September 21, 2023); the City of Phoenix soliciting atmospheric monitoring instruments—sensors, controllers, and alarms for hydrogen sulfide, methane, chlorine, and other hazardous gases at lift stations and treatment facilities (sealed offers due September 4, 2026, five-year term); and the City of Arlington, Texas requesting proposals for a cyanide flow analyzer for wastewater treatment operations (proposals due September 10, 2026). Cooperative purchasing vehicles and multi-year contracts dominate the structure; DBE participation, insurance requirements, and local-vendor preferences appear frequently in Phoenix and other jurisdictions.
