The Water Works implementation guide can help interested individuals work with schools and community partners to increase access to free, high-quality drinking water sources in their schools. It provides a comprehensive description on how to start a school water program, including how to: 1) build a team and gather support for the program; 2) test water quality and remediate problems; 3) choose a water delivery option; 4) conduct promotional activities and implement policies to sustain the program; and 5) monitor progress and make improvements. The guide provides policy- and program-based strategies to improve access to water throughout the school day. It also provides ideas, materials, and resources to help increase water consumption in schools.
