Montara Force Main Condition Assessment Using Non-Destructive Technology- Live Webinar

Includes a Live Event on 10/21/2021 at 12:00 PM (PDT)


Force mains are critical to any wastewater conveyance system, but it can sometimes be difficult to assess their conditions due to the nature of underground and pressurized utilities. In this webinar, we will walk through the condition assessment process for a critical force main on the coast of California, from the initial site walk to the finish report. Two types of non-destructive technologies (NDT) will also be featured in this talk: a detached free-flowing acoustic sensor, and an electro-magnetic scanning device.

Attendees will learn about a utilities first-hand experience of deploying these two types of device, interpreting their results, and lessons learned from this effort.
