Our team had a blast at this year’s Children’s Water Education Festival, where we had the opportunity to inspire the next generation of environmental stewards and future leaders of water! We connected with hundreds of enthusiastic 3rd, 4th, and 5th graders, teaching them about the water cycle, how everyday actions impact water resources, and simple ways to conserve, like identifying and fixing common household leaks. Through our “Seek the Sneaky Leak” activity, students saw firsthand how even small leaks can add up to significant water waste over time. A big thank you to our partners at @ocwaterdistrict for their continued leadership in hosting this impactful event. We’re already looking forward to next year! #MNWD #OCWA #ChildrensWaterEducationFestival
