1. 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.

CGMA and GTUA

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.

2. Are water service and sewer line warranties available?

Water Service and Sewer Line warranties

The City of Anna has partnered with Service Line Warranties of America (SLWA) to offer protection for your water service and sewer lines. The coverage is 100 percent optional and not required by the city. You may receive mailed letters with information on how to enroll in the optional program. If you'd like to opt out of the SLWA communications, call 1-844-257-8795.

3. Why is my water pressure low?

The presence of calcium can build up over time in water heaters, on faucet heads and showerheads. The build-up looks similar to a white/grey/light brown "scale." The scale is formed when the heat energy inside a water heater separates calcium from the water. Calcium deposits will accumulate on the heat exchangers over time and, if left unchecked, will lower your water heater's efficiency and reduce pressure in hot water lines. The issue is more pronounced in tankless water heaters, where the heating elements work at a much higher temperature to provide instant heat to the water passing through the tank. In addition, the lack of a tank means that this build-up will be more likely to impact your system if not addressed every year with proper maintenance.

4. Why is the water soft?

The city’s water source is well water, it is the mineral compounds in the water which makes it “soft”.
