Sewer Manholes

This set of punctual data shows the manholes located on the Island of Montreal. These manholes are compartments through which sewers can be accessed in order to clean, inspect and maintain them. The manholes are placed at regular intervals on the right-hand section of the main pipe. In straight sections, the maximum distance between two manholes is 120 meters. The manholes are generally placed at the beginning of a network, i.e. at the head of the furthest section and at the points where the pipe changes direction, altitude, slope and/or diameter. The information associated with the geographic data corresponds to the type and material of the manhole, date of installation, status, owner and jurisdiction.

CAUTION: This data is published annually, so it does not include updates made during the year. For this reason, they should under no circumstances be used for engineering purposes without validation by the City.
