Have you ever wondered where your tap water comes from? Or what makes that water safe to drink? YLWD hosts tours each year for those who live or work within YLWD boundaries. Tours are hosted by YLWD staff and are designed to give residents an opportunity to learn more about YLWD and to answer your questions regarding the District. YLWD Tours offer customers a chance to get a behind the scenes look at our facilities to learn how our water system works, meet the people who work diligently to provide high quality, safe drinking water to your home, help you understand your water supply, and become a more efficient water user.
