Metro Vancouver plans to build Second Narrows Water Supply TunnelMetro Vancouver plans to build Second Narrows Water Supply Tunnel<div class="ExternalClass46F298CD21404217801A2E72CA59BC4A"><p>Metro Vancouver is planning to build a new water supply tunnel under Burrard Inlet to meet the growing demand for safe, reliable drinking water in the region.</p><p>The new tunnel, slated for east of the Ironworkers Memorial Bridge, will replace existing water mains that are nearing the end of their service lives. It is one of five new water supply crossings across the region being built to higher seismic standards to withstand a major earthquake. </p><p>Construction of the water supply tunnel will involve:</p><ul><li>two tunnel shafts and a deep bored tunnel crossing under Burrard Inlet;</li><li>three steel water mains in both shafts and tunnel;</li><li>valve chambers at each shaft site; and </li><li>connections to the existing water distribution system that feed into the Seymour and Capilano reservoirs. </li></ul><p>The preliminary design phase of the project is complete and a detailed design is underway. The project’s north entry shaft and laydown area will be contained within Metro Vancouver’s Beach Yard, immediately north of Burrard Inlet and east of the Seymour River in the District of North Vancouver, while the south exit shaft will occupy a forested area of Second Narrows Park (formally Montrose Park) immediately south of Burrard Inlet in the City of Burnaby. </p><p>Second Narrows Park is just north of the Burnaby Heights residential community and is home to the Burnaby portion of the Trans Canada Trail, which is frequented by cyclists, runners, and dog walkers. </p><p>Our public involvement team plans to start a constructive dialogue with small businesses and residents near both the entry and exit shafts well in advance of construction. This is will help to ensure important issues, such as their experiences of the park during construction, or the effect of increased truck traffic on their business operations, are at the forefront of our mitigation work. </p><p>Construction of the project is expected to begin in 2018 and be completed in late 2022. </p></div>http://www.metrovancouver.org/metroupdate/PublishingImages/issue34-tunnels.jpg2017-07-31T07:00:00ZGP0|#2c0fce0a-9b46-4bae-b276-c523188c6aa3;L0|#02c0fce0a-9b46-4bae-b276-c523188c6aa3|Issue 34;GTSet|#d14ffe11-45dc-48fb-8684-ff109cf15a74<div class="ExternalClassD7C9B080646742AE9035D34EE0F474F8"><p>​Metro Vancouver is planning to build a new water supply tunnel under Burrard Inlet to meet the growing demand for safe, reliable drinking water in the region.
