Water conservation (level three)

Level Three of the King County Green Schools Program covers water conservation. Use our best practices and resources to engage students and staff in taking steps to reduce water use in your school, district, and community.

Schools use water for drinking, cooking, and cleaning, for classroom instruction such as in science labs, and for irrigating school gardens and grounds. Through education and action, schools can reduce our region's water use and protect this precious natural resource.
