Joel Harper, author of the popular children’s book “All the Way to the Ocean,” will be among the speakers and attractions at the South County Water Conservation Expo from 10 a.m. to 2 p.m. on October 1 at the Norman P. Murray community center in Mission Viejo.

The event, spearheaded by 5th District Supervisor Lisa Bartlett, includes demonstrations and displays on water efficiency from South County water agencies and the Municipal Water District of Orange County (MWDOC) as well as hands-on activities for children and speakers such as Harper.

Other presentations include an update on the Advanced Purified Water project for Lake Mission Viejo, “smartscape” landscaping by OC Coastkeeper and an educational, child-friendly program from the Discovery Science Foundation.

Trabuco Canyon Water will show how water is recycled, and El Toro Water District will bring out its emergency water-supply trailer.

Ricki the Raindrop, MWDOC’s rambunctious spokesdrop, is also scheduled to appear. For those who work up an appetite, a variety of food trucks will be on hand.

Norman P. Murray Center is at 24932 Veterans Way in Mission Viejo.
