HMCS Quadra Forcemain Replacement Project
A 50-year old sewer forcemain currently crossing the Courtenay estuary to service HMCS Quadra has reached the end of its operational life. A replacement pipe that maintains HMCS Quadra’s existing connection to the Comox Valley Water Pollution Control Centre will be installed beginning in April 2017. To reduce the environmental risk created by a cross-estuary crossing, the new pipe will follow the Goose Spit (Hawkins Road) roadway.
Construction on the roadway will run from mid-April to May 31, 2017, and an innovative drilling approach has been selected to minimize impact. In March 2017, a new route was determined for the pipe, which will now follow Hawkins Road right to the Croteau/Torrence intersection.
Construction updates/road closures
Maintaining access to Goose Spit Park and HMCS Quadra is a priority.
Current Road Notices:
- April 17, 2017: Work will proceed north from HMCS Quadra in 200m intervals. Expect single-lane alternating traffic around work areas.
There are currently two larger closures anticipated:
- Closure 1: A one-week full-traffic closure (except staff attending HMCS Quadra). Dates TBC
- Closure 2: A one-week pedestrian pathway closure between accesses to Stafford Road. Dates TBC
In 2014, the Department of National Defence (DND) and Comox Valley Regional District (CVRD) identified the need to replace the existing sewer connection currently running from the end of Goose Spit, across the estuary, to Comox’s waterfront. The aging asbestos pipe has reached the end of its operational life.
After assessing options for replacement, it was determined that a new route for the pipe that follows existing roads and right-of-ways would reduce the long-term risk of a pipe crossing the estuary and immediate risk of construction impacts on sensitive eelgrass and sand verbena habitats.
Goose Spit is a sensitive environmental area. To ensure its protection, the project team has selected horizontal directional drilling as the method of pipe installation. This requires minimal surface disruption.
The project is estimated to cost approximately $1.6 million, and is funded entirely by DND’s capital assistance program.
January 2017: An open house was held to provide info to the public about the project.
