Water Quality Reports

Annual Drinking Water Quality Reports

The annual Drinking Water Quality Report is a summary of important information about your drinking water and the efforts made to provide safe, high-quality drinking water. The 2023 Water Quality Report is the most recent report and was published in June 2023. Water Quality Reports for the year 2022 and earlier can be access in the Water Quality Report Archives.

Monthly Drinking Water Quality Reports

Every month the North Texas Municipal Water District (NTMWD) tests hundreds of waters samples for compliance with state and federal regulations. The monthly reports provide the results of the routinely tested parameters and the associated state and federal requirements. The City of Frisco receives treated water from the Wylie Water Treatment Plant. View the NTMWD water quality reports here.
