Please be advised, starting Monday, March 2, 2020, the City of Hays will begin its Free Chlorine Conversion to control distribution biofilm. It is essential that biofilm be eliminated from the system to ensure proper water infrastructure maintenance and quality. Biofilming is when a slight film can start to grow on the inside of the distribution pipe. Biofilming can cause water to have a bad taste and smell which can lead to nitrification which would cause corrosive water. The last Free Chlorine Conversion was performed in November 2018.
This common industry practice is used in cities throughout the country. The Temporary Conversion will be accomplished by changing from our usual combined chlorine process for 10 weeks. This will give the free chlorine process time to move through the entire distribution system.
Residents can expect a slight chlorine odor as the procedure moves through the system. The water is not harmful and is perfectly safe to use and consume. Once the conversion is completed, the City will return to its normal process of combined chlorine.The City of Hays regrets any inconvenience this will cause to the public but is necessary in order to maintain a healthy distribution system.Should you have any questions or concerns, please feel free to contact the Water Resources Department at 785-628-7380.
