Abstract

In the event of a failure of the main water supply to the UBC Vancouver Campus, an alternative source of water must be relied on. To address this need, Team 22 completed a final technical design for an emergency groundwater supply that provides a safe, sustainable, and resilient source of water for UBC’s population during an emergency. The final design consists of ten groundwater wells that will draw water from the aquifer located in the Quadra Sand Layer beneath the UBC campus. Both the wells and storage structures are in the Arthur Lord, Frank Buck, and Wolfson East fields in the southern section of campus, just east of Thunderbird stadium. The design makes use of a high production rate for a quick provision of water and minimal pump usage. The multiple wells provide ample resilience to the system allowing it to be confidently relied upon in an emergency. Due to the permanent underground storage tank, it will also allow UBC to use it for regular operation and lower their reliance upon Metro Vancouver. The design was evaluated based on criteria concerning economic, environmental, and social aspects to fully evaluate the designs sustainability. Team 22 has estimated the total cost of the project to be $2.66 million, including costs for the construction of the wells and storage tank, as well as operations and maintenance of the system. Construction of the project will take part in three main phases: well construction, storage construction, and project finalisation. It is expected to begin in May 2021 and last for 38 days. Detailed breakdown of the construction schedule and cost estimate are provided in the body of the report.
