Stanley Park Causeway watermain repairStanley Park Causeway watermain repair<div class="ExternalClassB71E39359F854AE5B73720D5A9F95746"><p>Metro Vancouver supplies over a billion litres of water from our three reservoirs to the region every day. We move this water using over 500km of water mains, some large enough in diameter to stand in, which often run under major road arteries. Expansion to support population growth and maintenance of the existing system are all part of our everyday work. </p><p>One of these mains, called <em>Capilano Main No. 4</em>, runs along a long narrow strip of land between Lost Lagoon and the Causeway in Stanley Park. It conveys water from the North Shore to Vancouver, Richmond and parts of Delta. In August of this past summer, the water main developed a leak, and required some significant repair work. It was an un-anticipated event, in a highly visible location, with very challenging constraints to overcome to get access to the actual leak location and complete the repair to the pipe. </p><p>How do you repair such significant infrastructure, all the while being mindful of keeping the water flowing to residents and businesses, and minimizing the disruption to traffic on the causeway and pedestrians on the Lost Lagoon pathway? It takes quick thinking, well-skilled crews, coordination among various parties, and some much appreciated patience from drivers, area residents and park visitors. </p><p>The pipe repair work involved the use of heavy equipment and work crews excavating about 5 metres down within a very narrow space, welding a steel plate onto the pipe at the location of the leak, and then reinforcing the pipe with a carbon-fibre wrap. The work was significant with the tasks affecting vehicle traffic scheduled over two separate weekends. Site restoration of the area followed, including re-establishing the pathway and final landscaping by the Vancouver Parks Board. </p><p>Metro Vancouver worked in cooperation with several agencies including the City of Vancouver and Vancouver Board of Parks and Recreation. We took to twitter, handed out notices to local residents, and worked with the media to get the word out during the repairs. </p><p>Metro Vancouver has a previously planned infrastructure project to twin the existing water main in this corridor that will proceed in the next few years. The new water main will provide both increased capacity and system redundancy. In keeping with Metro Vancouver’s water main naming protocols, this new water main will be called <em>Capilano Main No. 5</em>, and will be highlighted in more detail in a future newsletter. </p></div>http://www.metrovancouver.org/metroupdate/PublishingImages/Issue24-StanleyParkCauseway.jpg2016-09-27T07:00:00ZGP0|#e2b01bb7-c847-4927-b23d-b35b5af84a41;L0|#0e2b01bb7-c847-4927-b23d-b35b5af84a41|Issue 24;GTSet|#d14ffe11-45dc-48fb-8684-ff109cf15a74<div class="ExternalClassE6B57A7BB51F47E08C2877D11B77E7A6"><p>​Late this past summer a water main near the Causeway in Stanley Park began to leak.
