NIGP 83041: Leak Detection and Vapor Monitoring Equipment

NIGP 83041 Leak Detection and Vapor Monitoring Equipment, an Item code, encompasses hardware, sensors, controllers, and detection systems that state and local governments deploy to identify leaks in water lines, wastewater systems, chemical storage facilities, and confined spaces, along with atmospheric monitoring instruments that detect hazardous gases including hydrogen sulfide, methane, and oxygen depletion. Recent solicitations show purchasing bodies acquiring complete turnkey solutions—scanners with peripherals, installation, training, technical support, and maintenance contracts—rather than equipment alone. Issuing bodies span county detention facilities, school districts, municipal utilities, transit authorities, and water departments. The Pinellas County School District, Orlando Utilities Commission, City of Phoenix Water Services Department, and Orange County Transportation Authority have all posted opportunities under or closely aligned with this code within the past four months, signaling active procurement across both large and specialized jurisdictions.

Geographic activity concentrates in Florida and Arizona, with secondary representation in Texas. Representative recent opportunities include Collin County's RFP 2026-155 for a full-body scanner system ($242,000 first-year upfront cost, proposals due September 17, 2026, with mandatory pre-submission conferences in August); Pinellas County School District's ITB 26-CD-036 for leak detection services across school facilities (approximately $75,000 annually, bids due September 29, 2026); the City of Phoenix Water Services Department's IFB-27-0435 for atmospheric monitoring instruments at water and wastewater facilities (five-year term, sealed offers due September 4, 2026, subject to DBE-N participation requirements); and the Orange County Transportation Authority's IFB 250322 for methane detection system service and maintenance ($260,000 over four years, bids due June 1, 2026, subject to Davis-Bacon prevailing wage and DBE requirements). All recent opportunities emphasize non-destructive testing methods, compliance with safety and environmental standards, emergency response capabilities, and comprehensive reporting and integration with existing facility management systems.
