NWIC Upper Plateau Sewer Separation Project

Project Profile:

The Northwest Inner City (NWIC) Upper Plateau Sewer Separation Project is a multi-year project designed to alleviate flooding in the inner-city community of Sunnyside in Calgary, Alberta. The project includes the implementation of a large diameter storm trunk syphon to intercept stormwater from the upslope communities, bypassing Sunnyside and discharging directly to the Bow River. Trenchless construction was deemed necessary to minimize disturbance to the community and to traverse the change in topography from McHugh Bluff at the edge of the upper plateau to the lower elevation Sunnyside community and ultimately the Bow River.

The project was designed as a single 755 m long, 3,400 mm inside diameter (ID), tunnel drive between a launch shaft near the intersection of 10 Street and 8 Avenue NW and a reception shaft near the intersection of 7 Street and Memorial Drive NW, adjacent to the Bow River. The tunnel alignment consisted of two distinct sections: a deep section beneath McHugh Bluff through Paskapoo Formation bedrock that included a crossing of the Calgary CTrain metro line and a horizontal curve, and a relatively shallow section (less than three tunnel diameters of cover) along 7 Street within Sunnyside, initially through bedrock, but ultimately transitioning into alluvial channel deposits. This presentation will provide an overview of the project, discuss the design process and challenges, and provide an overview of the construction of the tunnel and outfall structure required to implement this critical storm water infrastructure for the City of Calgary.
