description: The University of British Columbia (UBC) Point Grey Campus is located within the region known as the Cascadia Subduction Zone. Scientists have indicated that a large magnitude earthquake is likely to occur in this region. When this earthquake happens the potable water supply mains going through the University Endowment Lands (UEL) may be cut off. The UBC Social Ecological Economic Development Studies (SEEDS) Sustainability Program has been exploring ways to provide water to the residents in such an event, so as to improve their resiliency under trying times. A leading option in their search is to utilize the water found in aquifers that are located below UBC, in the Quadra Sand layer. This final design report explains in detail how this will be achieved and also provides final detailed drawing sets. There are two aquifers in the Quadra Sand layer, containing about 5 and 15 metres of available water, respectively. During an emergency, there is enough water in these aquifers to provide potable water for the UBC residents for a period of about seven days. The main objective was determining what flow could be produced from a well installed in these aquifers. It was determined from our analysis that a well installed at a suitable location could produce around 15 litres per second. The next objective considered was understanding the demand flow rate. From analyzing the current usage some important areas came to the forefront: residential, academic research, and the hospital. Accommodating these and reducing in areas such as irrigation and laundry, brought the average demand to around 67 litres per second. Wells were located based on the thickness of the aquifer and available surface space. Additionally, drawing water from one well can impact the available water at a nearby well. This calculation was done and it was determined there will be enough water for all the wells to draw continually for the 7-day emergency period. Also of importance for well location was the thickn…
