Water Watchers Hawa'i
A Hands-On Water Stewardship Program
Water Watchers Hawaiʻi is a hands-on environmental stewardship program that empowers students to become freshwater guardians through science, investigation, and action. Building on PULS’s Become a Wai Steward unit, students learn about Hawaiʻi’s freshwater systems, groundwater, water quality, and the importance of sustainable water use.
Students conduct campus-wide Water Audits to investigate how water is used both indoors and outdoors. Working alongside teachers, custodians, and environmental experts, they collect data, observe water flow, and develop School Freshwater Use Guidelines focused on conservation and reducing runoff.
The program then moves into action, where students help design and lead a campus tree planting project aimed at improving groundwater capture and supporting healthier school environments. Guided by environmental professionals, students select planting sites and trees while learning proper planting and stewardship practices.
Water Watchers Hawaiʻi gives students real-world experience in scientific observation, collaboration, problem solving, and environmental stewardship while creating long-lasting impacts on their campuses and communities
