Understanding various types of consumers and their consumption patterns, changes in their water consumption trends in response to conservation strategies, and identifying the most influential variables of water usage, are key to support management and conservation strategies. In this work, our goal is to characterize the consumption of five consumer groups on a University campus including academic, education, dormitory, operations, and recreational buildings through daily water usage collected over several years. Water demand data grouped based on similar usage characteristics promotes the development of water demand models and informs water network managers on end-use consumption patterns to support management and conservation strategies. In this study, we have focused on data collection, time series and descriptive analysis to identify common attributes of university buildings with similar observed performance over time. Water demand profiles for 70 buildings across UT Austin’s campus, were aggregated by considering several consumption representative features, such as gallons per capita, gallons per square foot, and the buildings’ functional purpose. Housing was found to be the largest water consumer on campus and had the most consistent daily per capita use and water demand intensity profiles. Modelling efforts were focused on housing. Dormitory water usage was correlated with occupancy (number of residents and gender), day of the week (weekdays vs. weekends), and time of the year (i.e. academic seasons). The methods employed in this study demonstrate the ability to examine water usage trends across different buildings and to predict water demand profiles for un-metered buildings or new construction.
