On Monday morning, shoppers heading to the Vestal Walmart at the Town Square Mall were met with a surprise. Store associates told them the store was closed. By 10:30 a.m. the store had re-opened. 

The closure was due to a backup in the sewage line.

On Sunday, video of an outraged Vestal Walmart worker getting fired after showing what he said was raw sewage spread quickly on Facebook.

A corporate Walmart spokesperson told Fox 40 News Monday morning the murky discharge was not sewage, rather the results of clogged drains.

However, Chris Coddington of the Broome County Health Department said just because you can't see the fecal matter or paper from the toilets, it is still sewage.  Coddington added it was diluted sewage after it was flushed with water. Coddington said the store decided to close Sunday night.

Walmart said maintenance company Mr. Rooter addressed a second backup...this one on Monday morning. 

Coddington said that was caused after employees flushed the toilets Sunday night.

The company says kitty litter was put down to soak up the water and could have been mistaken for sewage. The Health Department said Walmart followed the proper steps. 

The department received the notice from a 911 call. They say the company would have been required to notify the health department if the backup had occurred in the food section. And added that none of the food facilities was impacted.  

The Town of Vestal of Supervisor's office said it had no information and that the matter does not involve the town.

Walmart corporate says it received that information from the store manager and would provide us what steps were taken to determine clogged pipes caused the backup.
