UBC Groundwater Emergency Supply Baker, Declan; Bean, Emma; Lorenzana, Aljhon; Mey, Alex; Prasad, Supreeth; Quero, Oscar

Abstract

Clean water is provided to the UBC Point Grey campus by Metro Vancouver through two water mains. The potential for failure of these pipes makes the system vulnerable in the event of an emergency. An alternate water supply that takes advantage of the groundwater in the aquifers below the campus has been designed on the request of the client, UBC SEEDS Sustainability Program. Key issues to consider while developing this design include determining how to most efficiently extract and deliver the water considering the features of the site, as well as determining the necessary water volumes and treatment. Methodology used for developing the detailed design involved implementing current best practices for the desired components while ensuring that the structure will be resilient enough to survive a potential seismic event. The team has prepared this detailed design report to present the detailed specifications and final construction plans for the project. The detailed design process was initiated once feedback was received from the client for the preliminary design report. The design of the project has now been updated and finalized; drawings and management plans are attached to this report. The main components of the detailed design are the eight groundwater wells that will be installed at the north end of campus, as well as the pipes, connections and pumps that need to be constructed to convey the groundwater into the system. The water treatment specifications and the structural designs for the storage and treatment facilities will be done by a sub-consultant, but the preliminary designs and criteria have been specified in this report. Additional considerations include the service life maintenance plan, the environmental impact assessment, permitting processes and the stakeholder engagement plan. Provided the construction starts in May 2021, the project is expected to be completed by November 15th, 2021. A draft construction work plan has been outlined and focuses primarily on ensuring that the construction is safe and efficient. A detailed cost estimate has been conducted and based on that, the project will cost approximately $9.07M, including construction costs and design fees.
