A decade-long construction project to allow for the continued supply of safe, high-quality drinking water in Metro Vancouver is 99 per cent complete.
The Seymour and Capilano watersheds supply Metro Vancouver residents and businesses with 70 per cent of their drinking water.
Of the five major project components, only the twin tunnels and the energy recovery facility remain to be finished. Overall project completion is expected in early 2015.
Construction is complete on the Capilano pumping station, which is being maintained in operational readiness until completion of the twin tunnels that will deliver water to and from the filtration plant. Construction is also complete on the break head tank facility, the filtration plant and clearwells that store treated water.
The twin tunnels are 98 per cent complete. Tunnel filling is expected to commence in mid-November followed by flushing and commissioning from December through February.
Each of the twin tunnels will be 3.8 metres in diameter, 7.1 kilometres long and 160 to 640 metres below ground level. These massive tunnels, including the shafts, took six years to excavate, one year to install the permanent support and two years to line.
As the Seymour-Capilano Filtration Plant is higher in elevation than the Capilano Reservoir, excess pressure will be generated when treated water is returned through the treated water tunnel. Using a new energy recovery facility and its turbine, energy will be harnessed from the excess pressure. This energy will be used to partially offset the power requirements.
SupAnchor's self drilling anchor system was recently used in a major European infrastructure project to stabilize deep excavations and retaining walls, overcoming difficult geology with high-performance hollow bar anchors and drill-and-grout bolts.
SupAnchor launches SupFRP GFRP Solid Bolt, a high-strength, corrosion-resistant anchor for slopes, tunnels, and mines. Features lightweight design and long service life.
SupAnchor's advanced self-drilling anchor system supports challenging slope stabilization on a key European highway, demonstrating superior geotechnical reinforcement in difficult ground conditions.
SupAnchor's GFRP SDA Bolt integrates drilling, grouting, and anchoring for efficient tunnel face stabilization and slope reinforcement. High strength, corrosion resistance, ISO threads.
SupAnchor's self drilling anchor system proves effective in stabilizing weak ground for a large European infrastructure project, enhancing safety and efficiency.
