Abstract: The objective of this report is to assess a variety of irrigation systems and make an informed recommendation to the committee responsible for implementing the new Student Union Building rooftop garden at UBC. While reviewing this paper, the reader should take note that the water source and its availability were not included within the scope of research. It was assumed that access to a reliable supply of potable water would not be an issue. The following three systems (1) Drip Tape, (2) Sub-irrigation and (3) Conventional sprinklers were analyzed extensively using a triple-bottom line assessment. This evaluation process consisted of examining the ramifications of all possible economic, environmental and social issues. The result is that water consumption, recyclability and durability or life expectancy emerged as critical features to compare. While each system had their own strengths and weaknesses, it was determined that a conventional sprinkler system would both meet the crop watering demands and, if installed correctly, serve as a worthy demonstration piece on sustainability.
