Greg Wilson/Anderson Observer
A boil water advisory was issued Tuesday night for Electric City Utilities customers, which covers most of the City of Anderson and some surrounding areas.
Electric City Utilities, a division under the City of Anderson Department of Utilities, provides water for about 38,594 residents.
Customers are advised to boil water used for drinking, cooking, brushing teeth, or making ice.
Approximately 150,000 gallons of untested water was accidentally released back into the system while performing tests during routine maintenance on the Orr Street water tank.
The utility expects testing will be done and the advisory ended sometime Wednesday morning.
Updates will also be available at the City of Anderson's website, or by calling the Electric City Utilities Water Operations Department at (864) 231-5230
