In 2008, the Alberta Capital Region Wastewater Commission initiated an upgrade of the St. Albert pump station facility, which was comprised of two interconnected and aging pump stations.

The building was designed with an innovative 21m circular footprint atop a 17m deep sunken caisson; this design approach was chosen due to poor sub-soil conditions, and a high groundwater table that made conventional excavation difficult.

As the facility is located in a residential neighbourhood, extensive public and stakeholder consultation was conducted, as well as the creation of a 3D fly-through video. The pump station was officially opened in June 2014.
