Condition Assessment of the City of Winnipeg Sewer Interceptor Network - 2014

AECOM Canada Ltd.

Winnipeg’s Interceptor Sewer Network includes 119 kilometers of pipe up to 2250 mm diameter in size and at depths approaching 20 meters. It is full of pipes that are very complex to access, under high flow regimes and it contains the most critical wastewater pipelines in the City’s system. The oldest pipes in the system were built as monolithic tunnels in the 1930’s and prior to 2009 very little was known about the physical condition of the overall system as logistically it was no possible to inspect it by conventional means. AECOM in conjunction with the City, implemented a program from 2010 – 2013 that used advanced multi-sensor technology platforms to enable the assessment of the inventory.
