The Cobb County Water System reported two wastewater sewer overflows occurred May 20.

The first incident was estimated at 9,720 gallons.

The overflow, resulting from a creek crossing that was broken in several places, occurred at 5071 Willow Point Parkway in Marietta. The break caused sewage to spill directly into a stream that is a tributary to the Timber Ridge Branch.

The Water System was notified of the overflow at 1:53 p.m. and the overflow was stopped by 4:35 p.m.

Water System employees repaired the creek crossing by replacing the broken main. Workers also spread lime around the spill area.

The second incident was estimated at 1,170 gallons.

The overflow, resulting from grease, occurred at 389 Shiloh Manor Drive in Marietta. Upon arrival, Water System employees located a trail of gray water in a tributary upstream from Noonday Creek. The spill area was 6-feet by 30 feet.

The Water System was notified of this overflow at 9:45 a.m. and the overflow was stopped by 1 p.m.

Water System employees unstopped the blockage with a jet machine, then cleaned and spread lime around the area.

In April, there were two major sewer overflows.
