Santa Rosa Water Presents our 3rd Annual FAMILY FUN DAY! This year we are excited to feature the Laguna Wastewater Treatment Plant. Everyone is welcome to join in the FUN! At our FUN DAY you can help paint a community watershed mural designed by a local artist, take a guided tour of the wastewater treatment plant, participate in hands-on activities, and enjoy educational opportunities featuring the Laguna de Santa Rosa and local wildlife, and a whole lot more!
