About 13,500 gallons were spilled from 8:30 p.m. until 1 a.m. Once waters receded, OWASA workers cleaned and disinfected the area.
OWASA in is the process of designing a new, larger sewer line in the area to to increase capacity. That project is estimated to cost $840,000. Construction will start in late fall.
