City spokesman Markus Owens said the city’s Department of Environmental Services received a call at 10:15 a.m. today and arrived on scene 45 minutes later.

The spill was stopped at 11:25 a.m., Owens said.

Approximately 1,050 gallons of untreated wastewater was spilled, with 10 gallons entering a nearby storm drain. City crews were able to recover 100 gallons of sewage, with an additional 940 gallons dissipating into the ground.
