Orinda WTP Disinfection Improvements Project
WHEN: April 21, 2026, 5:30 PM to 7:30 PM
Venue: EB MUD TRC
375 11th Street, Oakland
Come learn about East Bay MUD’s most expensive single project in its history, the Orinda Disinfection and Chemical Safety Systems Improvements project.
This $341 million project involves a massive improvement to the East Bay MUD’s most important treatment plant, a must-run facility which serves 800,000 customers.
This project is built 65-feet below ground surface and it includes almost every element of complex underground construction – 72-feet deep secant pile wall walls for excavation support, tie-backs under the existing plant and creek, several tunnels up to 10-foot diameter, automated geotechnical instrumentation, and complex shoring systems for existing structures. Come learn about geotechnical, structural, and hydraulic challenges faced building this project which is wedged in between sensitive wildlife habitat and utility lifelines.
A construction project tour will be provided for a limited number of people prior to the dinner presentation. YMF members have priority for registration. Spots are limited, and are first come first served.
Cost: $20 (ASCE members) / $30 (non-ASCE members) / $1 (asce Student members)
Dinner is included with the cost of attendance.
