From March 18 through April 29, the City of Falls Church will conduct its annual water main flushing program during which time the disinfectant in drinking water will temporarily switch from chloramine to chlorine.
The annual switch in water disinfection is part of a routine program to clean and maintain water distribution systems in the District of Columbia, Arlington County and Falls Church. During the temporary switch to chlorine, each local water authority will also conduct system-wide flushing to enhance water quality. This program is standard practice for many U.S. water systems that use chloramine during the majority of the year.
Individuals and business owners who take special precautions to remove chloramine from tap water, such as dialysis centers, medical facilities and aquatic pet owners, should continue to take the same precautions during the temporary switch to chlorine. Most methods for removing chloramine from tap water are effective in removing chlorine. Individuals with special health concerns should consult a health care provider on the use of tap water.
During this time, individuals may notice a slight change in the taste and smell of their drinking water. Chlorine taste and odor may be reduced by running the cold water tap for approximately two minutes and refrigerating cold tap water for a few hours. Water filters are also effective in reducing chlorine taste and odor.
While the water system is being flushed in their immediate area, customers may notice lower water pressure and discolored water from sediments being flushed from the system. Discolored water should become clear within minutes by running a cold water tap.
