Starting Monday, the city of Hays will begin its routine distribution system burnout in an effort to control distribution biofilm. It is essential 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 and cause corrosive water. This is the fifth time the city has used the burnout procedure. Specifically, it took place in 2006, 2009, 2011 and 2013.

The 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 burnout will be accomplished by changing from usual combined chlorine process for four to six weeks. That 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 few days. The water is not harmful and is safe to use and consume.

Once the burnout is completed the city will return to its normal process of combined chlorine.

The city regrets any inconvenience this might cause, but is necessary in order to maintain a healthy distribution system.
