City to Begin Using Alternate Water Disinfectant

The City of Corpus Christi is planning to change water disinfectant temporarily to stabilize areas in the water boil advisory and to further protect the entire water system. This change in disinfectant has been approved by the Texas Commission on Environmental Quality (TCEQ) and is planned to begin in the early morning hours of Monday, September 7, 2015. The water distribution system will change from the current chloramine (chlorine & ammonia) mixture to a straight chlorine disinfectant.

The change in disinfectant will be temporary and last for the next 30 to 60 days. Due to the different chemical nature of the disinfectants the City wants to inform those affected before initiating the change.

The City Utilities Department will continue its extended flushing and monitoring program to insure the water system remains in compliance. During this change in disinfectant, the smell and taste of chlorine could be strong and could temporarily appear cloudy or discolored. Recommendations for reducing the chlorine taste or smell include:

  • Aerating (shaking, or stirring) water in a container
  • Refrigerating
  • Opening faucets 3 to 5 seconds prior to use

The City has prepared a Frequently Asked Questions (FAQ) fact sheet about the chlorine disinfectant (see attached). The City continues to make strides in improving chlorine levels in order to remove the water boil advisory in the three areas identified with low chlorine. For more information visit www.cctexas.com or call 826-CITY. The customer call center will be open special hours on Sunday, September 6, 2015 from 3 – 8 p.m. to answer any questions residents have regarding the change in chlorine disinfectant.
