Refill, Reuse, Repeat: How Water Bottle Filling Stations Enhance Low-waste Drinking Water Consumption Through Nudging

Design for sustainability and design to change habits are two areas that have been explored separately. Design for sustainable behavior has started to be researched for different purposes. This research focuses on how we interact with objects to reinforce sustainable actions, focused on low-waste drinking water consumption using Water Bottle Filling Stations. Things do not work the same in different contexts, even if they are targeted at a similar group of people in two different countries. In consequence, the habits around particular objects change as well. This research is part of a bi-cultural study on the relationship between users and Water Bottle Filling Stations in universities, sites where these devices have been installed to promote healthy habits and encourage sustainable practices in their population. This is to evaluate the use of current nudges attached to the design attributes on the artifact.Using mixed methods, this research explored the possibility of using Water Bottle Filling Stations to create and reinforce habits in the user’s routine and the consequences with the aid of nudges. To understand these behaviors, populations from a college in Mexico and a college in the United States were subjects of study to understand the implications of using Water Bottle Filling Stations as a device that, by design, promotes reusability as a circular economy strategy. The following research did not aim to redesign the entire system but evaluate the impact of current nudges and design attributes on the artifact, how habits have affected culture, and supply a list of findings and recommendations.
