Denver, 2014: A Failed Storm Pipe Opened a Sinkhole at 9th and Washington
On May 29, 2014, a sinkhole opened at 9th Avenue and Washington Street in Denver. CBS Colorado reported that both streets were closed for several blocks in each direction. The cause was blamed on a broken storm sewer pipe.
A storm sewer is not the sanitary line that runs from your house. Storm pipes carry runoff. Still, the lesson carries over.
A failed buried pipe can wash out the ground around it until pavement drops. Old lines deserve a look before they collapse. Learn about trenchless sewer repair, or call the line and describe the problem.
