SALISBURY — More than a million gallons of city wastewater — some partially treated, some not — spilled into local creeks Sunday as a result of the heavy rain, according to a notice the city of Salisbury issued Monday.

Jim Behmer, head of Salisbury-Rowan Utilities, said the spills would not affect city drinking water and he didn’t expect any adverse environmental impacts.

The spills happened at two sites:

• About 305,080 gallons of untreated wastewater was discharged from Salisbury-Rowan Utilities’ Southside pump station on Kluttz Road in Rockwell. The discharge lasted for approximately 11 hours. The untreated wastewater entered an unnamed tributary to Dutch Second Creek.

• Other discharges took place at the Salisbury-Rowan Wastewater Treatment Plant on Heiligtown Road in East Spencer. They included approximately 392,309 gallons of untreated wastewater, approximately 191,899 gallons of primary treated wastewater  and approximately 120,400 gallons of secondary disinfection treated wastewater. The discharges lasted an average of eight hours and entered Town Creek.

All of the spills were due to the nearly 6 inches of rain that Tropical Depression Florence dumped on the area in just 72 hours, the city notice said.

Both Dutch Second Creek and Town Creek empty into the Yadkin River and are part of the Yadkin-Pee Dee River Basin.

Florence’s deluge has caused the Yadkin River to rise. Behmer said the river is expected to crest in the early morning hours of Wednesday about 9 feet above normal.
