DC Water has announced the start of its annual upkeep on the city's vast water line network. From March 25 through May 6, the essential process will take place without disruptions to the city's water service, though some residents may detect changes in the taste and scent of their tap water. This yearly procedure, a temporary disinfectant switch from chloramine to chlorine, is part of a routine to keep the distribution system in prime condition and preserve the quality of the drinking water provided to DC residents.
"The annual disinfection switch is just one of the ways we maintain our distribution system and ensure the delivery of exceptional quality drinking water," David L. Gadis, DC Water CEO and General Manager, said in a statement obtained by DC Water's news release. The temporary change, while guaranteeing to still meet all U.S. EPA quality criteria, means that residents might to suddenly notice a slightly off taste or a different odor from their taps.
The Washington Aqueduct, operated by the U.S. Army Corps of Engineers and supplier of water to DC Water, is responsible for the switch. They not only change the disinfectant but also add a corrosion inhibitor to maintain the water standards during this period. While the treatment is temporary, it’s instrumental in ensuring that the water mains remain clean, a key component of the district's public health measures.
To alleviate any potential discomfort with the temporary changes, DC Water advises customers to run their cold water tap for about two minutes or use a standard water filter. "If customers find the temporary changes in taste and/or odor objectionable, they may run their cold water tap for about two minutes and use a standard water filter," as per DC Water's guidelines. Furthermore, letting tap water to sit in a refrigerator for a few hours could also reduce the noticeable chlorine taste and odor. Those who have special water purification systems in place for chloramine are advised to continue their current precautions throughout the duration of this changeover.
While the switch to chlorine disinfectant is underway, the water utility company is committed to monitoring the levels of disinfectant to ensure they are safe for consumption. DC Water's customer service line is open for anyone who has specific health-related questions or concerns regarding the temporary change, with the recommendation to also consult with healthcare providers for personalized medical advice. The annual maintenance is a testament to the company's dedication to providing high-quality water services to its customers throughout the District of Columbia.
