An additional 100,000 gallons of sewage spilled early Thursday as crews worked to repair the broken 36-inch pipe that spilled 4.7 million gallons into Mallard Creek earlier this week.
Charlotte Water said the second spill occurred when a stream bank collapsed at the repair site just east of North Tryon Street and East Mallard Creek Church Road near UNC Charlotte. Most of the second spill was contained, the utility said, but some of it might have reached the creek.

The original incident happened when a tree fell on an underground pipe during storms Monday evening.
Crews were pumping sewage around the broken pipe early Thursday when the stream bank collapsed, dislodging a temporary line and spilling wastewater.
Repairs of the stream bank and the broken pipe will likely take another seven to 10 days, Charlotte Water said.
