UBC Groundwater Emergency Supply Detailed Design Report

UBC currently receives its water supply from the Metro Vancouver water system, which is reliant on two distribution pipes that direct the water through the University Endowment Lands. In the event of an emergency, these pipes may fail and leave UBC and the surrounding areas without a water supply. SEEDS (Social Ecological Development Studies) is exploring options for UBC’s on-site emergency water supply system, by evaluating the water demand during an emergency and utilizing groundwater wells, an emergency storage system, or a combination of the two to meet the demand. The Most Civil Engineering Consultants has created a detailed design to provide UBC with an emergency water supply solution. The detailed design provides an emergency water supply to meet the demands of UBC’s population and communities within a 1-hour walking distance. The total population considered was estimated to be 164,500 people. The water demand per capita was assessed, and a design was conceptualized that would meet the average flow demand that was calculated to be 3000 L/min and a 3-hour fire demand of 14,000 L/min. The site is on the south-east section of the campus, next to Library PARC, and will include four artesian wells, one 4.2 million liter water tank, and a main water distribution pipe along SW Marine Drive to the UBC pump house with a branch to UBC Farms. The project is estimated to cost $14.94 million CAD. Construction is planned to begin on May 2021 and with a duration of approximately 10 months. The cost breakdown and construction schedule included may be modified upon unforeseeable circumstances during construction. The performance, reliability, costs, environmental impact, and aesthetics all contributed to the decision-making process and development of the detailed design.
