Round Rock Begins Annual Water Line Flush May 27

Starting May 27, Round Rock’s utility department will conduct its annual water system maintenance by temporarily switching disinfectants from chloramine to free chlorine. The process, which runs through June 27, is a standard procedure aimed at keeping the city’s water supply clean and safe.

What Residents Can Expect

During the month-long flush, some residents may notice a slight chlorine smell or taste in their tap water. This is normal and does not affect the safety of the water, which remains fully safe to drink, cook with, and use for everyday needs.

Why the Change Matters

Switching to free chlorine helps prevent bacterial growth and mineral buildup inside water lines, particularly important during the warmer summer months when such risks increase. The flush is a routine part of Round Rock’s maintenance program to ensure long-term water quality.

Tips and Precautions

• If water appears cloudy or has a mild chlorine odor, running cold taps for a few minutes may help clear it.

• Residents with fish tanks, aquariums, or sensitive medical equipment should take special care, as free chlorine may require additional treatment or filtering.
