City of Mesa water customers who reside west of Val Vista Drive may experience subtle cloudiness in their water from October 15 through January. Residents can rest assured that their water is safe and continues to meet all state and federal water quality standards.
Cloudy water can result when the Water Resources Department temporarily switches from surface water to well water to perform routine treatment plant maintenance. In this case, the Val Vista Water Treatment Plant is having maintenance performed beginning in mid-October and will return to regular service January 2021.
"Dissolved air is often found trapped in groundwater," Water Resources Director Jake West said. "Our water distribution system is pressurized, causing any air that is present in groundwater to remain dissolved in the water until the pressure is released at the customer's tap. Dissolved air can cause water to have a cloudy or milky appearance, but it is safe to drink and will not damage plumbing or appliances."
