Officials: 3,700 gallons of sewage spills in North Carolina

The discharge happened at the Clinchfield sewer pump station in Marion when rainfall entered into the collection system Monday, the city said in a news release. The untreated waste water then spilled into an "unnamed tributary of Lake James" in the Catawba River Basin, the release said. 

At least six people were killed as Tropical Storm Isaias spawned tornadoes and dumped rain Tuesday along the U.S. East Coast after making landfall as a hurricane in North Carolina, where it caused floods and fires that displaced dozens of people. 

McDowell County, where Marion is located, saw an average of 3 to 4.5 inches (7 to 11.4 centimeters) of rainfall, The McDowell News reported. 

About 3,500 gallons (13,249 liters) of untreated water was discharged into the Catawba River Basin from the same sewer pump in May, The McDowell News previously reported. City officials had said that spill was also caused by excessive rain.

Marion is about 96 miles (154.5 kilometers) northwest of Charlotte.
