The Northwest Inner City Upper Plateau Sewer Separation Project is a multi-year project designed to alleviate flooding in the community of Sunnyside in Calgary. Associated Engineering proposed and designed the largest microtunnel in North America: a 765 m long, 3.4 m diameter microtunnelled inverted siphon, to intercept stormwater from the upslope communities, and divert it directly to the Bow River. Trenchless construction was preferred to minimize disturbance to the Sunnyside community and to traverse varying geology from the upper plateau to the Bow River. This passively operated solution has the benefit of saving both capital and operational costs.
