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. This is the fifth time the city has utilized the burn out procedure. Specifically this took place in 2006, 2009, 2011 and 2013.
This common industry practice is used in cities throughout the country. Regionally, Post Rock Rural Water District, City of Stockton, and many others burn-out annually.
The burn out will be accomplished by changing from our usual combined chlorine process for 4 – 6 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 odor should not last more than a couple of days. The water is not harmful and is perfectly safe to use and consume.
Once the burn out is completed the city will return to its normal process of combined chlorine.
The City of Hays regrets any inconvenience this will cause but is necessary in order to maintain a healthy distribution system.
