Johns Hopkins Take Back the Tap is a coalition of students and staff that are committed to reducing the JHU's consumption of bottled water and transitioning the campus to more affordable, sustainable and convenient tap water.  

In fall 2012 Johns Hopkins undergraduate students conducted an inventory of all drinking fountains in academic or administrative buildings on the Homewood Campus. Literally walking every hall, of every floor, of every building, they identified which fountains had been retrofitted with gooseneck bottle fillers, which were retrofittable, and which would need to be replaced in order to provide bottle filling capacity. Students also provided input on which fountains to target from a student traffic perspective so that renovations are strategically sound from an end-user standpoint. During the summer of 2013, Plant Operations and Office of Sustainability staff reviewed the audit, and worked with a contractor to develop a roll-out plan for retrofitting or replacing numerous water fountains across Homewood, with installation of units to commence during fall of 2013.

The Department of Housing and Dining has also been adding bottle filling stations to various residence halls, joining with the Office of Sustainability in the hopes of providing ample opportunity for students to make the right choice no matter where they live or study. Additionally, facilities staff at the School of Medicine and Bloomberg School of Public Health have been adding hydration stations to their buildings. Throughout the coming year the goal is to conduct a similar inventory of buildings on the East Baltimore campus, and work with student groups with those schools to evaluate which fountains to focus on first.
