Annacis Water Supply Tunnel




Annacis Water Supply TunnelAnnacis Water Supply Tunnel<div class="ExternalClassC7A40DF1AB30454E9576025BBA9B2507"><p>Metro Vancouver is constructing a new water supply tunnel deep under the Fraser River, between the City of New Westminster ​and the City of Surrey.</p><p>The Annacis Water Suppl​y Tunnel will be one of the five new marine crossings in the region built to withstand​ a major earthquake. When complete, it will help ensure the continued delivery of high-quality​ drinking water to the communities south of the Fraser River well into the future.</p><p>Construction will take appro​​ximately six years, from 2022 to 2028. It will involve building an entry shaft in Surrey and an exit shaft in New Westminster, and using a tunnel boring machine to excavate the 2.3-kilometre-long tunnel.</p><p>Once construction is complete, M​etro Vancouver will connect the newly constructed water supply tunnel to the regional water distribution system, and restore both shaft sites. Restoration will include creating a new green space for the community in New Westminster and replanting trees in Surrey.<br></p><p> <i class="fa-light fa-file">​</i> ​<a href="/services/water/ConstructionDocuments/fact-sheet-annacis-water-supply-tunnel-north-shaft-site.pdf" target="_blank">Annacis Water Supply Tunnel North Shaft Sit​e fact sheet</a>​​<br></p><p> <i class="fa-light fa-file">​</i> ​<a href="/services/water/ConstructionDocuments/fact-sheet-annacis-water-supply-tunnel-south-shaft-site.pdf" target="_blank">Annacis Water Supply Tunnel​ South Shaft Site fact s​heet</a>​<br></p></div>City of New Westminster and City of Surrey

Project activitiesProject activities<div class="ExternalClass8884ACDA712E4DC69AF2B0B309C5D23F"><p>The Annacis Wat​er Supply Tunnel has two project sites:</p><ol><li> <strong>New Westminster:</strong> Located at 11th Street, between Auckland Street and Royal Avenue. Construction in New Westminster will take place from early 2023 to 2028.<br></li><li> <strong>Surrey:</strong> Located at Grace Road, east of the Highway 17. Construction in Surrey will take place from mid-2022 to 2028.</li></ol><p>Main construction activities will include:</p><ul><li> <strong>Site Preparation:</strong> Our contractor will install temporary fencing around the site to ensure safety of crew, pedestrians, and cyclists throughout construction. This also includes the delivery of construction trailers, materials, and heavy equipment such as excavators and loaders to the site.<br>In New Westminster, the contractor will also install new utilities, and build a temporary four-metre-high elevated work platform on-site.</li><li> <strong>Shaft Construction</strong>: Once site preparation is complete, construction crews will install a retention wall around the tunnel shaft, and excavate the 60-metre-deep shaft. The contractor will then have divers seal the bottom of the shaft. During this phase, there will be high truck traffic to deliver and remove materials, and several pieces of heavy equipment such as cranes, loaders, and hydromill cutter will be on-site.</li><li> <strong>Tunnelling:</strong> After the shaft is built, crews will excavate a 2.3-kilometre-long tunnel beneath the Fraser River using a tunnel boring machine. This equipment will be launched from the entry shaft located in Surrey, and progress to the exit shaft in New Westminster.</li><li> <strong>Water Main Installation:</strong> Once the tunnel is excavated, the contractor will install a 2.6 m diameter steel water main inside the new tunnel.</li><li> <strong>Valve Chamber Construction: </strong>When water main installation is underway, the contractor will build a large underground valve chamber near the shaft. This activity will require specialized crews to install the pipe connections, valves, and other electrical equipment used to regulate water flow. The valve chamber will be large—approximately 15 square meters, and eight metres deep.</li><li> <strong>Water Main Connection: </strong>At the end of construction, Metro Vancouver will connect the new water supply tunnel through two local water mains to the existing drinking water distribution system. In Surrey, the connection will happen through the <a href="" target="_blank">Annacis Water Main South</a>, which is currently under construction. Metro Vancouver will also construct a new water main in New Westminster; we will share more details as the design progresses.</li></ul><p>Once the construction phase is complete, we will restore the projects sites to better or equal condition. Please read the section “Restor​​ation Plans” for more details.​​</p>​​ </div>
Restoration plansRestoration plans<div class="ExternalClassD2C0EC8AFE6040EAABA359F8AAF7AEB0"><p><strong>New Westminster (Nor​​th Shaft Site)</strong></p><p>Once the c​​onstruction is complete, Metro Vancouver will restore the roads to previous or ​better condition,​ and turn the project site into an open space for the community to enjoy.</p><p>We are integrating input fro​​m the local community, the City of New Westminster, as well as local First Nations into the design. It will include drought-resistant native plants and trees, and interpretive elements that help educate people about the drinking water infrastructure hidden deep underground.</p><p><strong>Surrey (South Shaft Site)</strong></p><p>Once construction is complete, Metro Vancouver will work with City of Surrey to ensure the site is restored in line with sustaina​ble practices to support the area’s biodiversity and ecological health.</p><p>We will replant a mix o​f different types of trees and shrubs, such as Sitka Spruce, Western Red Cedar, and Salmonberry. Any roadways impacted by this project will be restored to similar or better condition.​<br></p><br></div>

There may be times when construction crews will need to work longer hours or outside of the planned days to complete certain tasks. Metro Vancouver will notify the community about these activities ahead of time.</p><p>Typical hours of work for this project will be:</p><p> <strong>New Westminster​​ (North Shaft Site)</strong></p><ul><li> <strong>Monday to Friday:​</strong> 7:00 am - 8:00 pm</li><li> <strong>Saturdays:</strong> 9:00 am - 6:00 pm</li><li> <strong>Sundays and holidays:</strong> ​No work planned</li></ul><p> <strong>Surrey (South Shaft Site)</strong><br> ​Our contractor will be working 24 hours a day in Surrey, from Monday to Sunday, to maintain the project schedule. ​All work will comply with City of Surrey bylaw variances.​<br></p> <br> </div>
Impacts and mitigationImpacts and mitigation<div class="ExternalClass53A91068EFB64FAC890B18E0B802389B"><p>Metro Vancouver is committed to minimizing project impacts to the local businesses and residents located near the area where​ver possible. As part of our process, we identified potential impacts such as noise, traffic and dust early in the design stage, and planned the following measures to mitigate them during construction:</p><p><strong>Reducing Noise and V​ibration</strong></p><p>Constructio​​n activities will generate noise and vibration during work hours. The contractor will monitor noise to ensure the work is compliant with both municipalities’ bylaws or granted bylaw variances.</p><p>To reduce noise and vibra​tion impacts, whenever possible, our contractor will:</p><ul><li>Schedule work with our noisiest and high-vibration equipment, such as hydro vacuum trucks and jack hammers, to take place between 8:00 am and 6:00 pm</li><li>Minimize “nuisance noise”, such as offloading equipment, operating back-up beepers, or warming up heavy equipment</li><li>Cover noisy equipment while in use</li></ul><p><strong>Keeping People Moving Safely and Effectively</strong></p><p>We estimate an average of 15 trucks in and out of the site daily, with the exception of some construction periods where the site will receiv​​e 35-40 trucks a day.</p><p>To minimize traf​fic impacts in the area, our contractor will:</p><ul><li>Place traffic control personnel and signage around the construction area to ensure pedestrians, motorists and cyclists can safely move around the project site</li><li>Maintain emergency access to the area at all times</li><li>Provide temporary bridges or pathways during work that impacts public spaces</li><li>Maintain access to at least one sidewalk at all times</li><li>Remove equipment and obstructions to maximize public access to roadways and sidewalks after work hours</li></ul><p>Metro Van​couver h​​as also planned additional measures to minimize impacts specific to each of the shaft sites.</p><p><strong>In New Westminster:</strong></p><ul><li>​Contain the wo​rk within our site as much as possible in order to minimize disruptions to surrounding businesses</li><li>Restrict parking near the site only during major construction activities, except tunnelling</li></ul><p><strong>In Surrey:</strong></p><ul><li>Access and leave the project site via Grace Road and River Road. Residential streets will be avoided wherever possible</li></ul><p><strong>Managing Air Quality and Dust</strong></p><p>To minimize greenhouse gas emissions an​d dust, crews will:​<br></p><ul><li>Reduce vehicles idling time</li><li>Shut down equipment that is not in use</li><li>Sweep around the construction site to minimize dust​</li></ul><br></div>
