Repair and rehabilitate 152 m of a deteriorating 750 mm trunk sewer that runs through the Brick Pond wetland.
Project Start Date: January 3, 2017
Project End Date: March 31, 2019 (Projected)
The trunk sewer, constructed in 1960 at the northern limits of the Brick Pond wetland contains a 152 m section of 750 mm asbestos bonded, fully coated, paved invert, corrugated metal pipe placed on timber piles. Structural analysis has determined that typical relining or slip lining options could cause structural failure of the aging wooden support structure. Design has been modified to allow for a light-weight liner with increased flexibility.
