    By Jim Hegarty, PE I have been called in to look at a fair number of pipe failures over the course of my engineering career. One thing I notice is in the rush to fix the failure, there is often little focus on figuring out why the failure occurred. It is easy to miss clues […]

    The Gull Lake Sewer & Water Authority (GLSWA) operates a 4.4-mile long, 12-inch-diameter ductile iron forcemain. It handles nearly 500,000 gallons of sewage daily from the Village of Richland and the Gull Lake area. Rich Pierson, GLSWA’s Director, wondered for years about the 32-year-old pipeline’s condition. The problem: unless the pipe’s exterior is exposed, there […]

    We thought you might find this video interesting: [youtube http://www.youtube.com/watch?v=A3PGQX1krng] This was a pilot project with Detroit Water and Sewerage Department’s wastewater system for their pipe inspection consultant. The video helped them visualize the results of an extensive pipe inspection program using GIS. Prein&Newhof can produce similar information management and visual analysis tools for your system […]
