Latest News – Galveston County Water Control & Improvement District No. 12

Every year, the Gulf Coast Water Authority (GCWA) conducts an essential maintenance process to ensure the safety and quality of our drinking water. From April 7 to April 21, 2025, GCWA will temporarily switch its water disinfection method from chloramine (a combination of chlorine and ammonia) to chlorine only. This annual routine is crucial for maintaining the water system and preventing taste and odor issues, especially as we head into the warmer summer months.

What is Chlorine Maintenance?

During this two-week period, GCWA will flush the water system to remove any buildup that could lead to unpleasant tastes or odors. While this process is underway, you may notice some temporary changes in your water, such as:

Discoloration
Cloudiness
A stronger chlorine smell

Rest assured, these conditions are harmless and short-lived. The chlorine levels remain consistent with year-round standards, and the process has not been linked to any adverse health effects.

Who is Affected?

The chlorine maintenance will impact most Galveston County communities, with the exception of League City, Friendswood, and Bolivar. Municipalities and water districts will also flush their systems by opening fire hydrants to ensure the water flows smoothly through the pipes.

FAQs Answered

The GCWA has addressed some common questions about the process:

Dialysis Centers: Water used for dialysis is treated to remove all chemical disinfectants, so there’s no need for concern. Home dialysis users should consult their machine manufacturers for specific instructions.
Pets: If you have fish or reptiles, make sure to use water treatment products that remove both chlorine and chloramine.
Water Testing: GCWA will continue regular water testing every 4 hours to ensure safety and quality standards are met.

Why is This Important?

Water disinfection has been a standard practice in the U.S. for over a century, and it plays a critical role in keeping our drinking water safe. By temporarily switching to chlorine-only disinfection, GCWA ensures that the water system remains clean and efficient, especially in Texas’s high temperatures.
