OUR WATER: Upcoming disinfection change


SAN ANGELO, TX – Summer is right around the corner and San Angelo residents can expect a temporary change in their water. The annual change in disinfection of the municipal water supply is coming up. For most of the year the city uses chloramines to disinfect, but during the month of June, city water utility staff will be disinfecting with “free chlorine” only.

Water Utility Director Allison Strube highlighted the difference is between chloramines and free chlorine saying, “it is a mixture of ammonia and chlorine and it provides a longer lasting disinfectant throughout our distribution system. When we switch to free chlorine it is just the use of chlorine as out disinfectant in our distribution system.”

The change will take place from june first through july first, before reverting back to the standard disinfection method. According to city staff this is a common practice done by city utilities. What the change does is rid the distribution system of microscopic organic particles. With this change there may be a slight aroma of chlorine from municipal water, but it is still safe to use and drink.

“[Additionally,] citizens will see an increase in fire hydrant flushing during this month,” said Strube. “What we’re trying to do is get that chlorine mixture throughout the system and so you will see more fire hydrant flushing during that time.”
