Alameda Sewer Interceptor Pipeline Emergency Repair

Project Description

EBMUD will be making emergency repairs to a section of its Alameda sewer interceptor pipeline that was damaged during a storm drain excavation. The Alameda interceptor is a large diameter 60-inch pipeline that receives sewer flow from a number of City of Alameda sewer collections and conveys the wastewater to the District's treatment plant.

EBMUD crew will perform repairs on the existing large-diameter sewer main by excavating to expose a portion of the pipeline that was damaged, inspect the affected section, and install a protective cap to seal the sewer main. The cap will be securely attached to prevent wastewater leakage and protect the integrity of the sewer pipeline and will be cured with cement.

Workplan and Schedule

Construction and repair of the Alameda Interceptor Construction is anticipated to start on June 29, 2026 and be completed by the end of August, 2026. The construction is subject to change.

Work schedule

• Monday through Friday. 7 am to 3:30 pm.

What to expect 

• Construction equipment and materials will be temporarily located within the area.
• Noise from construction equipment is expected.
• Excavation around the sewer main will be needed to facilitate the repair of the interceptor pipe. 
• When construction is complete, all work areas will be restored to preconstruction conditions.
