Introduction
Motmot partnered with Detroit Water and Sewerage Department (DWSD) to inspect a newly installed section of 8-inch ductile iron water main in the City of Detroit. The objective was to provide clear visibility and provide a Risk Assessment report for the new section of pipe prior to its connection to the live distribution system.
Project Scope
Using our Autonomous Underwater Robot (AUR), the team performed a tethered, in-pipe run to document interior conditions and demonstrate how Motmot’s technology can be deployed during pre-connection or pre-commissioning stages of a pipeline project. This inspection allowed us to capture video, acoustic, and temperature data. Motmot delivered a Risk Assessment Report that provided DWSD with early insight into system readiness before the water main was brought online. This pilot inspection also served as our first deployment with a municipality and was designed to show Motmot’s inspection workflow and field operations. Around 12 DWSD staff members joined us on-site and were able to gain familiarity with our capabilities and inspection methodology.
