(TYLER MORNING TELEGRAPH) - The City of Tyler uses chloramines — a combination of free chlorine and ammonia — to disinfect its drinking water supply prior to distributing it to customers. This is a reliable disinfection process that has been recommended by the Texas Commission on Environmental Quality for systems predominately treating surface waters, such as those comprising the majority of Tyler’s water supply.
However, it is standard industry practice to periodically convert chloramines back to free chlorine as a measure of improving and maintaining the highest water quality standards in potable water distribution systems. In addition, the Environmental Protection Agency and the TCEQ support this process as a necessary and effective measure for maintaining water quality. Free chlorine is the disinfectant the city used for many years prior to converting to chloramines.
The city will begin converting its disinfection process to free chlorine for a period of about 60 days beginning Monday and ending on Sept. 30. Generally, there are no noticeable changes in water quality as a result of this temporary conversion. However, some individuals may notice taste and odor changes and a slight discoloration to the water.
The city will implement directional flushing, combined with routine water monitoring, as measures to remove iron particles from water lines and to maintain the highest water quality for customers during the conversion. However, some iron particles may still make it into customers’ service lines despite the city’s efforts. Customers who experience discoloration should temporarily flush faucets, tubs and toilets until their water has cleared.
Clothing should not be washed during times of discoloration so as to reduce the possibility of staining. Prior to washing clothing, customers may want to run a little water in their bathtub to check for discoloration.
Periodic pressure drops may also be experienced due to the city’s extensive flushing efforts. Noticeable water quality changes associated with conversions are normally short-lived and are not associated with public health risks. Customers can safely consume and use their drinking water as normal during the conversion period.
After the conversion period, the city will convert its disinfection process back to chloramines. Should you have questions or concerns regarding this temporary disinfection conversion, call the Tyler Water Utilities Service Center at 903-531-1285.
