Clairmont Road Water Main Fixed

A boil water advisory for the Century Center area has also been canceled.

The DeKalb County Watershed Division has canceled a boil water advisory for the Clairmont Road area. The DeKalb County Watershed Division completed repairs on a 30-inch water main in the 2900 block of Clairmont Road on Monday.

County technicians working with the Georgia Environmental Protection Division collected and tested water samples in the area. The boil water advisory is canceled effective immediately.

Watershed crews had been working on the compromised water line since Wednesday. The cause of the damage was the failure of a transition joint between two pipes: a cast iron pipe in place since 1941 and a steel pipe added in 1963.Β 

Repair efforts were hindered by four factors: 1) The difference in the material between the pipes; 2) the corresponding difference in outside diameter; 3) the non-standard modifications to the coupling device that was utilized in 1963; and 4) the failure of three isolation valves – likely caused by old age.

To complete the repairs, Watershed Management reduced pressure in an area bound to the north by Plaster Road, to the east by I-85, to the south by Briarwood Road and to the west by Buford Highway. The Georgia Environmental Protection Division regulations require a minimum of 20 PSI in the system at all times. When a low pressure event occurs, a potential health hazard may exist in those areas of lowered pressure from backflow and/or back-siphonage of water into the water distribution system.

The water was restored to the system Friday and the boil water advisory was issued. Technicians began sampling the area Friday afternoon.

Watershed crews will continue to work on external repairs and restoration of the excavation sites and pavement throughout this week.
