As part of Drinking Water Week, we are hosting a poster contest for 3rd, 4th and 5th grade students throughout the OCWA service area to showcase their ideas of What Do You Know About H2O? Submissions should fit on a 8½” x 11” piece of paper or smaller. Voting will be done by the OCWA Board of Directors and staff. Multiple winners in each grade will receive cash prizes. For more details, please refer to the official rules and fact sheet.
