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.

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.

Water Hardness

If you are experiencing cloudy or spotty dishes, you may need to adjust your dishwasher for hard water build-up. Minerals dissolved in water may leave deposits behind after water is heated and evaporated. View more information about Water Hardness.
