This data was generated during a study to evaluate how the installation of water jets (drinking water dispensers) in New York City public schools affected student consumption of water and milk. Data was collected from 9 schools which received the intervention and 10 comparison (control) schools at three points: pre-intervention/baseline in November 2010, 3.5 months after installation in March 2011, and 10 months post-intervention in September 2011 after the beginning of the new school year.

Data was collected through three methods: cafeteria observations; surveys to students in grade 5, 8, and 11; and interviews with cafeteria managers. Cafeterias were observed two days before and two days after water jet installation for the number of times each water source was used and the number of times milk was taken. Cafeteria managers were interviewed about their experiences with the water jets, implementation and maintenance of the water jets, and student interaction with the jets. Students completed a survey with 26 multiple choice questions about their food shopping behavior, key demographic characteristics, and opinions and beliefs about water consumption.
