NIGP 49052: Leak Detectors, Vacuum: Helium, Ultrasonic, etc.

NIGP 49052 Leak Detectors, Vacuum: Helium, Ultrasonic, Etc., an Item code, covers acoustic and AI-based leak detection systems deployed across water infrastructure networks, along with underground locating devices and potable water testing services that support leak identification and water quality assurance in state and local operations. State and local governments procure under this code to detect leaks in potable water pipelines, locate underground utilities, and conduct regulatory-compliant water quality testing at treatment facilities and operational sites. Recent solicitations show a mix of issuing bodies: water utilities and departments (City of Scottsdale Water Resources), county public health labs (County of Santa Clara), county sheriffs and emergency operations (County of Orange), and state transportation departments (Utah Department of Transportation). These vary from large infrastructure programs spanning multiple years to routine compliance testing and specialized equipment acquisitions.

Activity is concentrated in the Southwest and California. The City of Scottsdale, Arizona issued RFI 26RFI075 (due May 27, 2026) for an AI-based leak detection program covering 62–310 miles of potable water pipeline, structured as a 10-year corporate-funded turnkey solution requiring acoustic sensors, data analysis, and post-repair validation through the Bonfire portal. The County of Orange, California released IFB MA2976301MB2 (due March 10, 2026) for potable water inspection and testing services at sheriff facilities with quarterly sampling, 24-hour emergency response requirements, and pricing structured as flat quarterly fees plus hourly labor rates, offering five to eight percent price preferences for County of Orange Local Small Business and Disabled Veteran Business Enterprise certified bidders. The Utah Department of Transportation issued a sole-source notice (February 17–25, 2026) for four Radiodetection 7200 underground locator devices from California Surveying & Drafting Supply at $32,180 total estimated value, justified as the only equipment capable of detecting fiber optic lines beyond 20 feet depth. The County of Santa Clara posted RFI RFITSSFY260686 (due April 22, 2026) for a lab information management system replacement for public health operations.
