Today I came to Greg’s Woodbine home to evaluate the sanitary sewer. Greg has explained that 4 years ago the main sanitary sewer backed up. The city of calgary cleared the line and there has been no issues since then. Greg is concerned that there may be problems lurking in the sewer and would like the line inspected to find any problems that may cause the line to back up in the future. Upon camera inspection I found the internal and external abs piping is in good condition. At 19 feet from the cleanout (mid back yard) there is a very minor pipe belly that is holding less than a 1/2” of sewage. This is not a concern. At this point the pipe transitions to a white pvc piping system. This system has no errors until just past the property line at approximately 31 and 32 feet where there is a broken pipe allowing root intrusions. At 41 feet in the alley, there is a major pipe misalignment allowing an extreme root intrusion. The city of calgary is responsible to repair or replace the damaged
