A boil water advisory has been issued for part of an east Forsyth subdivision.

Officials with Cumming Utilities notified residents that a boil water advisory went into effect at 3 p.m. on Tuesday on part of Sweetwater Drive and all of Highpoint Road, Crestwood Place and Birchwood Court in the Sweetwater subdivision off Buford Dam Road. The advisory will remain in effect until at least 3 p.m. Wednesday and could last up to 48 hours.

Cumming Utilities Director Jon Heard said in an email the advisory was taken “out of an abundance of caution” after a 6-inch PVC water main broke. Crews repaired the line by 3 p.m.

Heard said the water main was repaired, flushed and a bacteria sample was sent to the department’s lab and results should be available within 24 hours. He said the “chlorine residual is within normal limits.

Fifty-two homes in the subdivision will be impacted.

A hanger left on the doors of residents said outages can cause health hazards due to the “backflow and/or back-siphonage of water of unknown quality into the distribution system and recommended residents boil water before using it for drinking, cooking or preparing baby food.

Water should be boiled for at least a minute after reaching a rolling boil.
