Investigation finds wastewater didn’t spill into Blanco River after city lift station failure

An investigation by SMTX Utilities personnel and the Texas Commission of Environmental Quality found that an equipment failure at a City of San Marcos Wastewater Lift Station didn’t cause untreated wastewater to spill into the Blanco River.

The City of San Marcos announced Wednesday that approximately 225,000 gallons of untreated wastewater overflowed into the Blanco River after the equipment failure. But the investigation showed that wastewater discharged near the river but not into it.

The city said the equipment failure happened late Monday evening at the lift station located in the 2200 block of River Road. The city said its water supply, however, was not affected by the spill.
