Decade-Long Seymour-Capilano Twin Tunnels Filtration Project Completed Decade-Long Seymour-Capilano Twin Tunnels Filtration Project Completed <div class="ExternalClass53FE802673E94ECD9FA9CE1521B51B5F"><p class="ExternalClass97B1D77C80334B2F97B51E387BBCB3E6"> Representatives from the provincial government, Metro Vancouver and its Member Mmunicipalities, Vancouver Coastal Health, and local residents attended the ceremony celebrating the $820-million <a href="/services/water/WaterPublications/SCFiltrPlant2010.pdf" target="_blank">Seymour-Capilano Filtration Project, comprising the Twin Tunnels</a>, <a href="/services/water/quality-treatment-testing/treatment-facilities/drinking-water-treatment-facilities/Pages/default.aspx" target="_blank">the Seymour-Capilano Filtration Plant</a>, Raw Water Pump Station, Energy Recovery Facility, and Break Head Tank adjacent to the Capilano Reservoir. </p><p class="ExternalClass97B1D77C80334B2F97B51E387BBCB3E6">This major infrastructure project allows water from the Capilano Reservoir to be carried through one tunnel, treated at the <a href="/services/water/quality-treatment-testing/treatment-facilities/drinking-water-treatment-facilities/Pages/default.aspx" target="_blank">Seymour-Capilano Filtration Plant</a>, be carried back to the Capilano system through the second tunnel for distribution, and further secures water supply for Metro Vancouver residents.</p><p class="ExternalClass97B1D77C80334B2F97B51E387BBCB3E6">At 3.8 metres in diameter, 7.1 kilometres long, and 160 to 640 metres below ground level running beneath the North Shore mountains, the Twin Tunnels are an engineering and construction feat. As the Filtration Plant is at a higher elevation than the Capilano Reservoir, excess pressure is available from the returning water for which an energy recovery system has been created. The recovered energy will partially offset the power requirements for the Capilano Raw Water Pump Station.</p><p class="ExternalClass97B1D77C80334B2F97B51E387BBCB3E6">The completion of a major project like this not only represents over 10 years of physical work, it represents vision and planning, ingenuity, and input from and coordination with local residents. The Twin Tunnels will ensure a supply of safe, high-quality drinking water for future generations in Metro Vancouver.</p> <p class="ExternalClass97B1D77C80334B2F97B51E387BBCB3E6">Metro Vancouver and its<a href="/boards/membership/board-members/Pages/default.aspx" target="_blank"> Member Municipalities</a> are committed to providing clean, safe drinking water to residents and businesses of the Lower Mainland at a reasonable cost.
