SEWER & WATERMAIN CONSTRUCTION
Gordon Trunk Sewer Rehabilitation
City of London, Ontario - 2009
Reconstruction of Beachwood Avenue in London between Ridgewood Crescent and Southcrest Drive, including the replacement of all underground sewers and water infrastructure for a length of approximately 430 metres. The replacement of the existing 1050 mm diameter sanitary sewer with a new 1350 mm diameter sewer, required continuous bypassing of flows which was accomplished through a system of 4-300 mm diameter bypass pumps including 100 % redundancy for base flows. Another major challenge on this project was the space limitation given the depth of the existing trunk sewer (5.0 metres). A temporary water supply system was used to partially address the space constraints during construction of the new sewers and 300 mm diameter watermain.
