WATER MAIN INSPECTION AND ASSESSMENT

Project Owner: City of Phoenix
Project Type: Job Order Contracting
Construction Dates: 06/19 to 06/24

Achen-Gardner is provided the support services required to shut down, dewater, assess, and start-up large diameter water transmission mains (42” and larger) throughout the City of Phoenix. Our work was completed within a fixed time frame by following a MOPO (Maintenance of Plant Operations) with strict attention to detail. We completed four Job Orders (JOs). 

We inspected a 4,400-foot-long, 48” diameter section of Scenario 21, a PCCP transmission main. This section runs under the Salt River and could not be dewatered so the team, including design engineering firm Black & Veatch, utilized a robotic electromagnetic inspection tool which can crawl through full pipelines. The team used the 1080p camera and electromagnetic sensors to assess the pipe and discover any wire breaks.
