City of Hays-Free Chlorine Conversion beginning March 15, 2022

The City of Hays will temporarily convert the disinfectant used in the distribution system from chloramine to free chlorine. The conversion will begin on March 15th and continue through May 23rd. During this period, you may experience taste and odor changes associated with this type of temporary disinfectant conversion. 

Public water systems are required to properly disinfect their water and maintain an adequate disinfectant residual in the distribution system. Chloramine, free chlorine combined with ammonia, is widely used as a disinfectant because it persists for longer periods while also limiting the formation of disinfection by-product contaminants. Prolonged use of chloramine may result in the growth and/or persistence of organic matter within the pipes of the distribution system. Other factors that can impact water quality, such as high temperatures or reduced usage of water, may hinder the ability to maintain an adequate disinfectant residual.

The Hays Fire Department is conducting their annual flow testing of all 1,034 hydrants at this time to rid distribution pipes of this organic matter to improve the quality of your water overall.

 If you have questions regarding this matter, please contact the Department of Water Resources at 785-628-7380.
