2 MD Counties No Longer Under Essential Water Use Warning

Updated, Wednesday at 5:27 p.m.

MONTGOMERY COUNTY, MD — Nearly 2 million residents across Maryland were under an essential water use warning after a power outage on Tuesday impacted a water utility.

WSSC Water said in a Wednesday update that the warning issued to both Montgomery and Prince George's counties was lifted as of 5 p.m.

The power outage had impacted the provider's Potomac Water Filtration Plant at 12200 River Road.

While power was restored to the plant by Tuesday afternoon, the essential use order remained in place until the system resumed normal operating levels.

Water remained safe to drink and no boil advisory was issued during the outage and recovery period.

The utility had previously warned that if the electrical matter had not been solved, a boil water advisory would have taken effect. "This is a rapidly evolving situation," WSSC Water said at the time.

Steps To Take During Essential Water Use Alert

WSSC says customers can take the following steps during essential water use advisories.

• Use water only as necessary – i.e., take shorter showers and quickly turn off faucets immediately after use.
• No outdoor water use, including lawn irrigation systems.
• Limit flushing toilets (do not flush after every use).
• Limit using washing machines and dishwashers.

Approximately 75% of WSSC customers receive potable water from supplies processed at the plant.
