Port Mann Water Supply Tunnel



Port Mann Water Supply Tunnel and Associated Water MainsPort Mann Water Supply Tunnel and Associated Water Mains<div class="ExternalClassC87C40A30F0D4C31AFAF0191245474CB"><p>Metro Vancouver is undertaking two major infrastructure projects in Surrey and Coquitlam to ensure the continued supply of safe, clean drinking water to residents and businesses in the region. </p><p>The first project is called Port Mann Water Supply Tunnel which runs underneath the Fraser River from Maquabeak Park in Coquitlam to Surrey. This project involves burrowing an 80-metre-long tunnel 30 metres below the riverbed and installing a 2.1 metre-diameter welded steel water pipe through the tunnel. This new water supply tunnel is expected to be complete in Spring 2017.</p><p>The second is the Port Mann Water Main Project which involves installing a new 1.5 meter-diameter water main and valve chambers on either side of the Fraser River in Coquitlam and in Surrey. Construction began in fall 2015 and is expected to be complete in fall 2016. </p><p>Once the water supply tunnel is complete and the associated water mains are installed, they will be tied-in to each other and ultimately be connected to the existing pipeline system. Together, these projects will more than double the capacity of the existing water supply system and accommodate the region’s future population growth. </p></div>Under the Fraser River near Port Mann Bridge and on the north and south sides of the Fraser River, Coquitlam and Surrey.

Project Update

  • Noise associated with construction - July 29, 2016

    Starting August 2, 2016, crews will install plates and rails into the ground that make up the supporting walls of access pits for the tunneling work underneath Lougheed Highway and the Canadian Pacific Railway tracks, from Colony Farm to Cape Horn Avenue. This procedure will prevent soil movement and reduce groundwater from seeping into the pit.

    Residents and businesses in the area will hear intermittent noise due to the hammering of plates and rails by an excavator and from other equipment used to complete the installation. This work will take approximately four weeks to complete and is a requirement to safely complete tunneling work activities. Crews will be working six days a week from 7 am to 5 pm.

  • Temporary lane closures along Lougheed Highway starting as early as June 28, 2016 - June 21, 2016

    Crews will begin to install a portion of the water main underneath Lougheed Highway, from Colony Farm to Cape Horn Avenue. Work will start as early as June 28, 2016 and is expected to last for approximately four months. The following traffic pattern changes will be in effect:

    • The ramp along United Boulevard, exiting east to Lougheed Highway, will be temporarily closed during this work. Eastbound traffic must continue along United Boulevard and take the next ramp on the right, before making a left turn at the traffic light at Lougheed Highway.
    • Eastbound Lougheed Highway, between Colony Farm Road and United Boulevard will experience lane diversions to allow space for the necessary work. Highway speed limits will be reduced when approaching this area.
    • Changes to traffic signal timing at the following intersections will be implemented to reduce possible traffic congestion: 
      • Lougheed Highway and Colony Farm Road
      • United Boulevard ramp to eastbound Lougheed Highway
  • Pipe Installation in Coquitlam - From Cape Horn Avenue to Mariner Way - March 18, 2016

    ​Metro Vancouver's contractor began installation of the 1.5 metre diameter water main in Colony Farm Park in mid-January 2016. Crews are now mobilizing to construct the portion of the water main which will be installed from Cape Horn Avenue to Mariner Way. Work starts on March 18, 2016 and will last for approximately four months.
