Where does my water come from?

About our Water

Our City water system is supplied through a combination of treated surface water from the North Texas Municipal Water District and well water from multiple wells in our community.


The City of Anna is a member of the Collin Grayson Municipal Alliance (CGMA). The four members of the CGMA are Anna, Melissa, Van Alstyne, and Howe. The four cities all receive treated surface water from North Texas Municipal Water District through a system managed by the Greater Texoma Utility Authority (GTUA). The GTUA manages a pump station in McKinney, Texas, a large-diameter water main from McKinney to Howe, and storage tanks in both Howe and McKinney. This infrastructure is what brings the treated surface water to the CGMA cities.

Water Treatment

The Utility Operations Division of the Public Works Department routinely monitors our drinking water for potential contaminants. All sampling, testing, and treatment of drinking water are done in accordance with the Texas Commission on Environmental Quality standards. These standards ensure that public drinking water is safe for our neighbors.
