An investigation into installing waterless urinals at Koerner’s Pub Garsuta, Red (Kyle); Too, Jason; Seth, Sidharth; Ruan, Daniel

Abstract

In alignment with UBC’s Sustainability goals, Koerner’s Pub is determined to lower its water consumption through practices, policies, or implementation of technology. Restrooms account for a significant portion of a restaurant’s total water consumption, mainly due to the vast amount of water flushed in the urinals. This report investigates into the possibility of installing waterless urinals at the Pub in order to eliminate water usage due to flushing. Using the Triple Bottom Line assessment, three different options are considered: keeping the existing urinals, installing new waterless urinals and retro-­‐fitting the existing urinals into waterless urinals. The investigation focuses on solutions that do not necessitate a large capital investment. After evaluating each of the three urinal options based on the triple bottom line indicators, it is found that keeping the existing flush urinals is the most economically feasible option due to high costs attached to the waterless urinals. Waterless urinals project a positive impact on the environment and are socially acceptable in places that do not have high user loads, such as Koerner’s Pub. Despite the mammoth potential water savings of approximately 47,000 liters per year, merits of waterless urinals are negated by the strong economic pushback. Since it would be impossible for the stakeholder to recover the costs for installation and maintenance of waterless urinals, it is recommended that the Pub management should just continue to use and maintain the existing flush urinals.
