Recent inspections identified structural deterioration, including significant corrosion and exposed rebar, requiring immediate attention. Crews will rehabilitate approximately 1,700 linear feet of pipe.
Measures are in place to help protect downstream drinking water infrastructure during the work. On a typical dry weather day, this section carries an average of 6 million gallons of wastewater and is located upstream of regional drinking water intakes.
Construction is expected to continue through September 2026.
