Watermain Installation Near Old Banff Coach Road S.W.

Construction to relocate a City of Calgary watermain continues.

  • watermain install OBCR visible
    Watermain construction just north of Old Banff Coach Road S.W.
  • watermain casting anchors
  • Watermain thrust block waterhelp.org
    Example of a thrust block (image courtesy of waterhelp.org)

The water moving through the pipe down this steep slope will speed up (increased velocity) and cause thrust (a propulsive force). The force of thrust on the pipe can cause the pipe to move and possibly even pull apart, so thrust blocks are used to anchor the pipe and transfer the thrust force to the surrounding soil.

Geotechnical Surveys

Geotechnical work started last week and will continue for several weeks.
