The City of Austin issued a boil water notice Monday morning; however, none of City of Round Rock’s water is treated through the City of Austin’s water treatment system. 

“Historic flood waters flowing into our water supply lakes contain very high levels of silt that makes it challenging for the water plants to produce the volume of water needed to supply customers at this time,” according to a news release from the City of Austin. Customers of the City of Austin Water Utility receive their drinking water from the Colorado River as it flows into Lake Austin.

The majority of City of Round Rock’s water is provided through surface water from Lake Georgetown, which is operated by the Brazos River Authority (BRA). The BRA also supplements the water in Lake Georgetown via a 28-mile pipeline from Lake Stillhouse Hollow, near Belton. Wells drilled into the Edwards Aquifer provide a small portion of the City’s water, typically less than 5 million gallons per day.

Although the City has contracted to purchase Lake Travis water from the Lower Colorado River Authority in the future, this water is not currently used by the City.
