Notice of Routine Preventive Maintenance

Notice of Routine Preventive Maintenance April 1, 2026 to April 30, 2026
As part of our efforts to ensure that the drinking water supply is the highest quality possible, Pendleton Water Supply Corporation, will temporarily convert the disinfectant used in the distribution system from chloramine to free chlorine. The conversion will begin on
April 1, 2026 and continue through April 30, 2026 During this period, you may experience taste and odor changes associated with this type of temporary disinfectant conversion. The water will remain safe to drink.
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 long periods while also limiting the formation of disinfection by-product contaminants. Prolonged use of chloramine coupled with other factors that can impact water quality, such as high temperatures or stagnation of water, may result in the growth and/or persistence of organic matter within the pipes of the distribution system, which may hinder the ability to maintain an adequate disinfectant residual. A temporary conversion to free chlorine, partnered with flushing activities, helps to rid distribution pipes of this organic matter and improve the quality of your water overall.
During this period the Pendleton Water Supply – Berry Utilities will be performing flushing activities throughout the distribution system. There may be periods of discolored water that will be temporary. Let your faucets run until the water clears up.
If you have questions regarding this matter, you may contact Pendleton Water Supply Corporation at 254-773-5876
