Company switches to “free chlorine” treatment during annual flushing program
DAVENPORT, IA (Oct. 18, 2017) Iowa American Water is temporarily adjusting its treatment process in the Iowa Quad Cities beginning today as part of its regular, ongoing water main flushing program. Continuing through November 18, the company is switching its disinfection method to a form of chlorine known as “free chlorine” which does not contain ammonia. This temporary treatment change only affects customers in the Iowa Quad Cities (Bettendorf, Davenport, LeClaire, Riverdale and Panorama Park). It will NOT affect customers in Blue Grass, Dixon or Clinton.
Chlorine is commonly used in public water systems as a disinfectant and is monitored closely by our water quality experts to ensure optimum levels are present. However, due to the change in the type of chlorine, customers who are sensitive to chlorine may experience a more noticeable chlorine taste or odor in their tap water. There is no reason for concern as the water will continue to meet all state and federal water quality regulations. These aesthetic differences are due only to the switch in type of chlorine in the water.
Customers with fish aquariums should take note of this temporary treatment change and determine whether it will affect their aquarium water, so they are able to take any necessary precautions.
The treatment change is being done in conjunction with our routine water main flushing program, which will be ongoing this fall. Crews will flush the distribution system from 8 a.m. until 6 p.m. during the workweek.
“The temporary switch in treatment is designed to make the routine flushing of water mains more effective and ensure we maintain our high quality water standards,” said Mary Jane Midgett, director of operations for Iowa American Water. “The flushing program is designed to maintain a high quality of water in the distribution system by flushing or cleaning mineral deposits and sediment from water mains. Over time, these sediments can build up in water mains causing discolored water and/or restricted flows,” she added.
While no interruptions in water service will occur as a result of the work, Iowa American Water advises that when crews are flushing nearby, customers may experience a drop in water pressure or some discoloration of their water. Iowa American Water recommends that any customers experiencing discolored water let their cold water run to clear before using it again and refrain from doing laundry during that time. Any water discoloration or low-pressure problems should last only a short period. If problems persist, notify Iowa American Water’s customer service line toll free 24-hours-a-day at 1-866-641-2108.
The water main and hydrant flushing will be performed by Iowa American Water crews who will be working out of utility trucks labeled with the company logo. All employees will also have photo ID badges.
