Proposed upgrades to the Buck Lake Dam and Magic Lake Estates (MLE) Water System will begin in late summer of 2012 and be completed by fall 2013. Two projects, one with several components, will run concurrently:
Buck Lake Dam Spillway Replacement
The design and construction supervision services for a new culvert and spillway at Buck Lake Dam were awarded to Klohn Crippen Berger (KCB). This structure is required to replace the existing corrugated pipe through the dam which the Ministry of Environment Dam Safety Branch (Dam Safety) has advised is unsuitable to meet present standards. This culvert was installed in 2009, on a temporary basis, when the previous one had deteriorated to the point it was jeopardizing the integrity of Buck Lake Dam. At that time Dam Safety approved the installation “on an interim basis” until MLE could fund the appropriate structure and they gave MLE until 2013 as the latest allowable completion date. KCB has now completed their design and the project has been tendered and awarded to G&E Construction in the amount of $457,200+HST. Construction will occur in September/October when Buck Lake is historically at its lowest level.
Buck Lake Dam has a “High Hazard” consequence rating, meaning that if it failed there would be a HIGH risk of damage to people and property downstream. The discharge culvert is designed to mitigate this risk. KCB has designed the inlet structure to the new box culvert to limit the outflow, even during the design flood event, to that which can be passed safely through the existing downstream culverts. The work will require removal of the existing culvert and replacement with a 1.8 m square concrete box culvert and inlet structure. During construction, access over the dam will be limited and once construction is complete access over the dam will resume.
Water Treatment and Infrastructure Improvements
Design and construction services for the second project were awarded to AECOM Canada Ltd (AECOM). The first part of the AECOM work was to undertake a review of the existing MLE system and determine the required water system improvements. This review was completed in September 2011.
AECOM have combined the work into a single contract which includes:
- New water treatment plant, to be located at the CRD yard at 47284 Schooner Way
- New raw water pump stations from Magic and Buck Lakes
- New raw water main from Buck Lake to the water treatment plant
- Replacement of the Frigate Reservoir at the existing site
- Replacement of some existing water distribution mains
AECOM has completed the final design phase for the works and will be tendering these works in May/June 2012 with construction starting in the fall and extending through 2013.
MLE received a 2/3 grant from the Building Canada Fund on these water treatment and Infrastructure Improvement projects. The overall grantable budget for these works is $6,925,000 with an additional $150,000 allocation for CRD to oversee the works and Consultant which is non-grantable.
