Notification of Water Supply Change

March 17, 2015

The District of Columbia Water and Sewer Authority (DC Water) advises customers who live in parts of NW Washington, DC that their drinking water will temporarily be supplied by the Washington Suburban Sanitary Commission (WSSC) this Wednesday, March 18, 2015 at 7:00 am until May 4, 2015 at 5:00 pm. The impact area is shown on the attached map, which can be found at the following link: http://bit.ly/1xejulz.

Customers may notice a chlorine odor or taste in the water due to WSSC’s use of chlorine disinfection. Please also be advised that the system-wide temporary switch to chlorine will occur on March 23, 2015.
Customers may notice a change in the taste and smell of drinking water. DC Water recommends the following:
• Flush cold water tap for two minutes.
• Refrigerate a pitcher of cold tap water and over time the chlorine taste and odor will dissipate.
• Use a pitcher-style or faucet mount filter to reduce chlorine taste and odor.

For additional information, please contact the Drinking Water Division at (202) 612-3440 (Monday-Friday, 8:00 a.m. – 4:00 p.m.) or the DC Water 24-hour Command Center at (202) 612-3400.

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.
