City Looks to Invest in New Water Infrastructure

You turn on the sink to wash dishes or shower for the day, but probably don’t think about the process of getting water to your house. But there’s a lot of work behind the scenes before the water ever comes into your home.

The Southlake City Council approved an engineering services agreement with Freese and Nichols, Inc. during the February 4 session. Under the agreement, FNI will provide engineering design services not to exceed $318,171 for residual control systems located at the Pearson and T.W. King Pump Stations.

“The completed project will provide our water system operators with the capability to control chlorine residual levels within the water system per federal regulations,” Public Works Director Rob Cohen said. “Creating and eventually purchasing the systems is one way we’re investing in quality infrastructure for the community.” 

Once the design is complete, the City can plan to purchase and install the systems in the next several years.

The hypochlorite generation systems helps to keep the water disinfected and assists in emergency preparedness. The new systems are part of the City’s goals to continue to provide safe, compliant drinking water, optimize technology, as well as build and maintain our high quality infrastructure.

Funding for the design of the systems will be provided from the Utility Fund.

Measures to Maintain Water Quality Underway

You may have noticed the flushing of fire hydrants across the City over the last several weeks and wondered to yourself “what’s going on?”or “why is the City doing that?” In short, the purpose of the flushing is to maintain the quality of water during the winter months or periods of low consumption by ensuring that the water doesn’t stagnate or collect potentially harmful elements.

We aren’t alone in doing this. The City of Fort Worth recently sent out information regarding the flushing of their system as a preventative measure to maintain drinking water quality. In addition, a number of their 29 water customer cities (of which Southlake is one) are undertaking similar measures.

All in all, it’s a necessary practice to ensure the integrity of the City’s drinking water and, because of that, the City will continue to flush the hydrants as needed.

Customers May Detect Change in Taste & Odor of Drinking Water

FORT WORTH, Texas – Tarrant Regional Water District had to change the water source late Thursday afternoon for Fort Worth’s Rolling Hills Water Treatment Plant after a construction contractor struck the 90-inch water supply line from Richland-Chamber Reservoir. 

The Rolling Hills WTP is receiving a blend of water from Cedar Creek Lake and Lake Benbrook. Lake Benbrook water is of the most concern to customers because tests are showing elevated levels of geosmin, which cause taste and odor issues. Geosmin is not an issue in the water from Cedar Creek Lake, which means the blend should reduce the effects of the geosmin. 

Customers in south and east Fort Worth are most affected by this source change. This change is expected to last only a few days. Once the pipeline is repaired and returned to service, Rolling Hills will revert to the source water blend from Richland Chambers Reservoir and Cedar Creek Lake. 

In an attempt to mitigate the issue, the department has increased the dosage of ozone disinfectant, which can help with resolving taste and odor issues. The Water Department assures customers the water is safe for drinking, cooking, bathing and all other purposes, even though it may have an earthy smell and taste. 

Geosmin is a naturally occurring compound produced by bacteria in soil and algae found in surface water. Cold temperatures kill off the algae in surface water, and the dead algae release the geosmin. Customers may improve the taste of their drinking water by refrigerating the water in an open container; or adding a slice of lemon or lime.

The wholesale customers that regularly purchase water include Bethesda Water Supply Corp., Burleson, Crowley, Dallas/Fort Worth International Airport, Dalworthington Gardens, Edgecliff Village, Everman, Forest Hill, Grand Prairie, Haltom City, Haslet, Hurst , Keller, Kennedale, Lake Worth, Northlake, North Richland Hills, Richland Hills, Roanoke, Saginaw, Southlake, Trophy Club Municipal Utility District, Westlake, Westover Hills, Westworth Village and White Settlement.
