San Antonio High School IMPACT Team students attended Confluence 2018 at The Witte Museum


Confluence is a youth water conference that attracts 1,000 students citywide and is the capstone event for IMPACT, a project based learning program hosted by San Antonio Water System. The projects our IMPACT Teams showcased this year for the summit include the following:

The “Zoo Crew” worked with Bob Waterman at the San Antonio Zoo to install a drip irrigation system in two gardens at the zoo. This not only reduced the amount of water the zoo uses, but it also reduced the amount of man hours it took to hand water these areas.

The A&M Team worked with Dr. Valdez at Texas A&M University San Antonio. These students were hoping to use microbes to help native plants grow at the Riverwalk and crowd out the invasive Bermuda grass that is currently there. However, due to an early freeze and snow, the group had to move their project indoors. The students were great at changing their project to adapt to the unusual San Antonio weather, and in the end their results were exactly what they hoped they would be.

The third Impact Team worked with Elequa. They have created a device that will hold an LED light and a sensor around an electrocoagulation prototype. They then reprogrammed the device to work as an opacity sensor, which takes readings of the water as it cleans.
