Moccasin Powerhouse Bypass Needs Assessment

Client: Wastewater Enterprise/Construction Management Bureau-SFPUC 

 

Service: Construction Management 

 

Staff: Robert Davis, Joe Hill & Grace Samish

The Moccasin Powerhouse (MPH) utilizes an elevation drop of over 1,000’ to produce approximately  25% of Hetch Hetchy Power annually. The Powerhouse houses two turbines and generators each installed over 50 years ago, as well as existing bypasses that when used for extended periods of time have failed.  JHCE served in a lead role for the Needs Assessment Phase, and produced a report which identified feasible alternatives to bypass the powerhouse, ensuring that during an outage water delivery is not interrupted.
