From the Anderson County Water Authority:

Boil Water Notice – Marlow Community
Due to a break in a 20” main water line, we are issuing a boil water notice for the Marlow community out of an abundance of caution.
Water service crews are currently on-site and working around the clock to restore water service as quickly and safely as possible.
In the meantime, we ask all residents to please conserve water whenever possible.
We sincerely apologize for the inconvenience and will continue to provide updates as the situation progresses.
Thank you for your patience and cooperation.
