Abstract

The city of Ottawa, Canada, has been particularly conscious of winter sewer maintenance since 1931 when a severe and destructive explosion took place in the sewer system. A Civil Complaints Bureau with an explosion prevention section carries out continuous inspection of sewers and underground conduits. Bylaws have been passed to restrict the possibility of any flammable substance entering the sewer system. The cooperation of other utilities has been secured in detecting and reporting hazardous conditions through an Underground Utility Co-Ordinating Committee. These efforts insure that maximum spring thaws may be handled by the 800 miles (1,280 km) of city sewers.
