Community Outreach

Mesa Water’s robust outreach program helps to increase awareness of the District and water among key audiences.

Mesa Water also promotes the importance of conservation through public outreach and education programs. We are proud that our customers are using less water and have reduced water use by more than 20 percent since June 2015. We encourage you to keep up those water-wise habits and make improvements in your home and landscape when possible.

Additionally, we encourage commercial and industrial customers to use reclaimed water for greenbelt areas. Using reclaimed water for irrigation purposes saves drinking water for other uses.
