Providing Southlake with High Quality Drinking Water

The City of Southlake’s goal is to provide you with safe and reliable drinking water.

According to, over 90% of Americans get their tap water from community water systems, which are subject to safe drinking water standards.

We are happy to report that our water meets the safe drinking water quality standards as set by the U.S. Environmental Protection Agency (EPA) and the Texas Commission on Environmental Quality (TCEQ).

To ensure that our water is safe, the City takes chlorine samples throughout the distribution system every day to monitor the water for any abnormalities and collects 30 bacteriological samples every month in compliance with TCEQ and EPA requirements.

In addition to collecting samples, the City maintains seven water storage tanks that distribute water throughout our community.

These tanks are inspected annually, internally and externally, for structural integrity that involves evaluating the conditions of the foundation, protective coating, access points and vents and overall water quality.

The tanks are also drained and disinfected during annual cleanings.

Following the cleaning process, water is refilled and a sample is taken to verify that it meets safety and quality standards.

Once the results are received from the lab and the water is deemed safe, the tank is put back into the service cycle.

Information collected from the condition assessments are then compared to previous years so that any preventative measures can be taken to keep tanks and water they hold in superior condition.

What it Takes to Deliver High Quality Drinking Water

With an annual consumption of an estimated of 2.8 billion gallons of water, making sure you have high quality drinking water straight to your faucet is one of the City of Southlake’s priorities.

Our team works diligently daily, managing infrastructure, maintenance and improvements.

“Each day, we do our best to make sure Southlake has clean and safe drinking water,” City of Southlake Water Supervisor Kyle Flanagan said. “There’s a lot of hard work that goes into making sure the community can turn on their faucet and fill a glass with water.”

Every day, a team member takes routine chlorine samples throughout the distribution system to monitor the water for any abnormalities. This equates to about 300 samples per month. Southlake Water Utilities also collects 30 bacteriological samples every other month, all in compliance with TCEQ and EPA requirements.

From water towers to storage facilities, the water team keeps them maintained and working property. This includes painting, cleaning, replacing equipment and restoring failed parts.

The team also conducts annual “flushing” to maintain a heathy water system.  Southlake Water Utilities monitors tank levels, chlorine levels and pressures using SCADA, and also utilizes the BEACON software to compile data to make decisions based off usage patterns of the City as a whole.

Systems that Work – How Southlake Maintains a Sustainable Water Infrastructure

Drinking water is essential to the well-being and health of those who live, work and play in Southlake.

The Southlake Public Works Department teams up with other City departments such as Finance and Planning and Development Services to invest in maintaining and updating our water infrastructure. Public Works utilizes a ranking system which identifies and prioritizes projects essential to maintain critical assets. The department also abides by Environmental Protection Agency guidelines to provide quality and safe drinking water.

Water quality is maintained daily by flushing water hydrants, taking samples and monitoring to ensure facility operations are working properly.

Earlier this year, the City invested in renovating the elevated storage tank located on Miron Drive. Southlake cleans and inspect our tanks to ensure they meet and exceed the Texas Commission on Environmental Quality and American Water Works Association standards. After performing a series of inspections and cleanings, the tank was recommended to be repainted.

The City conducts annual inspections and cleanings on all water storage tanks to prevent a build-up of sediment which can settle in the bottom of the tank. Sediment left too long inside a storage tank could create a place for bacteria to form. When bacteria forms in a tank, the water in the tank can lose its disinfectant residual and adversely impact the water quality in the entire pressure plane or even an entire water system.

The renovation of the interior and exterior coating also prevents the corrosion of steel and the oxidation of the paint. The integrity of the water tower’s interior paint coating is essential to maintaining the infrastructure needed for quality and safe drinking water.   A smooth, non-porous surface helps ensure the tank is clean and free of issues.

The City also recently replaced 20-year-old pump valves at the T.W. King Booster Station. These valves play a critical role in the operation of the tank by pumping water from the City’s wholesale provider (City of Ft. Worth) to the water towers, which is then distributed to homes and commercial facilities in Southlake.

By strategically investing in public assets, such as water infrastructure systems, the City can continue to provide their customers with the highest quality drinking water.
