A Prevention Research Center Tool Showing Evidence of Effectiveness


The Water Jets Evaluation Tools analyze how installing water jets (drinking water dispensers) in New York City school cafeterias affects what and how much students drink. The tool kit includes student surveys, an observation form, and a key informant interview. These forms evaluate use of the water jets, perceptions about drinking water, attitudes about beverage choices (including milk and sugary drinks), and changes to how often students drink water and other drinks.


A team of researchers used the tools to study the influence of water jets on children’s choice of water and milk in New York City public schools during the 2010–2011 school year. Nine schools in one group received water jets, whereas 10 schools in a control group did not. The study showed a three-fold increase in children drinking water, both at 3 months and at a year after the water jets were installed at the schools.1
