The San Francisco Public Utilities Commission's contracting opportunities list, updated on October 28, 2026, includes Moccasin Powerhouse Systems Upgrades (HH-1023), estimated at US$50 million, with earliest advertisement in December 2026. It is one of several contracts SFPUC is lining up at its Moccasin facilities on the Hetch Hetchy system.
A dam project in procurement
For the Moccasin Dam and Reservoir Long-Term Improvements, SFPUC advertised a construction manager/general contractor request for qualifications and proposals in the April–June 2026 quarter. The project is forecast at US$162.21 million. Proposals for a related US$26 million construction management staff augmentation contract were due on November 4, 2026.
The larger jobs behind it
Two bigger Hetch Hetchy projects frame the work. Mountain Tunnel, a non-redundant link in the regional water system, is in construction at US$268.67 million and forecast to finish on June 3, 2027. The Moccasin Penstock Rehabilitation, which would replace penstocks built in the early 1920s, is in planning at a forecast US$533.70 million, against US$331.17 million approved, with completion forecast for December 31, 2036.
Budget room
The 10-year capital plan adopted on February 10, 2026 raises Hetch Hetchy Water capital to US$1,864.1 million, up 21.5% from the previous plan, with dam safety and penstock work among the drivers.
