Crews in San Marcos are cleaning up after Wednesday's rains led to an overflow of 800,000 gallons of untreated wastewater combined with rainfall.
The overflow sprang from the city's wastewater collection system just outside the main lift station located at 502 River Road. It began about 7 a.m. and ended at 1:25 p.m., according to the city.
"We had a lot of rainwater. That's the reason for this," Assistant Director of Public Service Jon Clack said. "We have monitoring equipment up there, and we knew the levels were getting high."
The untreated wastewater was largely diluted by the rainwater, Clack said, and does not pose a threat to the environment or residents.
