DeKalb County on Monday afternoon lifted its boil-water advisory for the entire county.
"Authorities have confirmed that the water supply in all areas of the county is safe for consumption without boiling," the county said in a statement.
Two three-minute power outages on Friday night prompted DeKalb County to issue the boil-water advisory on Saturday morning. Thunderstorms were blamed for the outages at the Scott Candler Water Treatment Plant on Winters Chapel Rd., which treats water drawn from the Chattahoochee River.
Even though backup generators restored power within three minutes each time, the county's Department of Watershed Management was obliged to check water quality after water pressure dropped to dangerously low levels in parts of the system.
DeKalb County was under a three-day county-wide boil-water advisory in March of 2018 when a large water main broke along Buford Highway. A broken water main also caused a three-day county-wide boil-water advisory in July 2015.
On average, thunderstorms occur in DeKalb County on an average of 50 to 55 days every year. Storm-related electrical power outages are not uncommon.
