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!

Thank you to everyone who joined our recent Fix-a-Leak workshops in celebration of the @EPA's National Fix-a-Leak Week!

Our water efficiency experts led hands-on sessions focused on identifying and repairing common household leaks. Participants learned how indoor and outdoor water systems function, how to detect irrigation leaks, and how to fix common toilet leaks using simple tools.

It matters: a single leaky toilet can waste more than 200 gallons of water per day and add over $500 to your annual water bill!
