Service learning projectThe San Antonio Water System Impact Team program is an award winning program that promotes STEM, water education and civic responsibility through service based learning. It provides meaningful community service combined with academic study and encourages students to develop their own water ethic while empowering them to positively influence our environment, society and economy. Impact Teams are comprised of groups of middle or high school students that design and facilitate a water related service project during the course of an academic year. In the spring each year they showcase their projects at a one day summit called Confluence.
