Event Information:

The Town of Aurora, located in Ontario, Canada, had been facing capacity constraints within its sewage system network, leading to historical overflow events at its main pumping station, the Aurora Sewage Pumping Station (SPS). To address the climate change preparedness and mitigate issues within the Aurora raw sewage pumping system, the Regional Municipality of York (York Region), retained WSP Canada Inc. (WSP) to conduct a Schedule B Class Environmental Assessment (EA) and Preliminary Design. The objective was to determine the preferred solution to alleviate the capacity constraints at the Aurora SPS. The Class EA was conducted for the service area generally located between Bathurst Street, Henderson Drive, Yonge Street, and Bloomington Road, within the Town of Aurora.

The preferred solution from the Class EA was to build a SPS to service the Henderson Drive Service Area due to its least impacts on the social environment, natural heritage, and economic effects. The purpose of this new regional infrastructure is to redirect wastewater from the Henderson Drive Service Area away from the Aurora SPS. The main focus of this presentation is to discuss constructability challenges associated with the deep sewage pumping station, associated inlet sewers and discharge forcemains in the environmentally sensitive Oak Ridges Moraine.
