Notification of Temporary Water Supply Change in Northwest DC

November 18, 2014

The District of Columbia Water and Sewer Authority (DC Water) advises customers that live in parts of NW Washington, DC that their drinking water will temporarily be supplied by the Washington Suburban Sanitary Commission (WSSC) this Thursday, November 20, starting at 9 p.m. The impact area is shown on the attached map, which can be found at the following link: http://bit.ly/1xejulz. The temporary switch in water supply will last approximately 6 to 8 hours while DC Water makes a repair to the pump station that serves this area. Customers may notice a chlorine odor or taste in the water due to WSSC’s use of chlorine disinfection and the mixing of DC Water and WSSC water supplies. The stronger chlorine taste and smell should subside by Sunday, November 23. If the odor and taste persists after Sunday, DC Water recommends that customers call the Drinking Water Division at 202-612-3440. DC Water also advises customers that water pressure should remain constant, although a small increase is possible due to the temporary supply change.

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. 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. Please share this information with everyone who drinks this water, especially those who may not receive this notice directly (for example, people in apartments, nursing homes, schools, and businesses).

For more information and updates, visit www.dcwater.com or contact DC Water Customer Service at 202-354-3600 or the 24-Hour Command Center at 202-612-3400.
