Another sewage overflow in Tega Cay has prompted a no-swim advisory this week in a Lake Wylie Cove.
Between midnight and 9 a.m. Monday, Tega Cay Water Service says approximately 100,000 gallons of partially treated sewage flowed into a cove off Marquesas Avenue.
It’s not the first time this has happened in Tega Cay.
Catawba Riverkeeper Rick Gaskins says the problem comes when aging pipes are inundated with heavy rainfall.
Gaskins says even though Tega Cay Water Services’ owner, Utilities., Inc., has identified how much sewage was spilled, no one can really tell for sure.
Utilities, Inc. did not return calls for comment Thursday afternoon.
A search of our news archives shows previous sewage overflows occurred at least four times in the last five years.
Earlier this week, the company said the sewage spilled out of the sewer system and flowed into an adjacent storm drain that empties into the cove.
Utilities, Inc. crews spent much of the day Monday working at the site.
The no-swim ban will ultimately be lifted by the state health department when daily samples show normal levels of bacteria in the water.
