Investigation of the Ida-Raisinville Sanitary Sewer Pipe Distress
Abstract
The US Army Engineer District, Detroit, oversees grants for the Environmental Protection Agency (EPA). However, with little inspection authority, the Corps is forced to conduct only limited inspection and sometimes only forensic study of potential problems. The Ida-Raisinville sanitary sewer project, funded as an EPA grant, was determined to be unacceptable only after the project was essentially complete and acceptance pressure tests were conducted. After failing pressure specifications, a TV camera survey was conducted and it was determined that there were a minimum of 100 cracks (mostly circumferential) in a section of the project comprising about half the total footage of installed sewer line,. To put the sewer in service, it had to be determined whether the pipe failure was continuous, what the probable cause of failure was, and what would be a reasonable and economical repair scheme. Keywords: Compaction; Concrete pipe cracks; Distress. (JES)
