The City of Irving and North Texas Municipal Water District (NTMWD) jointly operate and maintain an 84-inch raw water transmission line. In the summer of 2015, aerial survey revealed that the 84-inch raw water line had been exposed and undercut where it crossed the South Sulphur River and was at risk for failure. Our speakers will discuss the challenges faced during design and construction of emergency pipe stabilization and permanent channel erosion protection, all completed while this crucial piece of infrastructure remained in service.
