Our Water Enterprise manages a complex water supply system stretching from the Sierra Nevada Mountains to San Francisco. As sound stewards of this engineering marvel in our care, we never stop maintaining and upgrading it.
Projects
Regional Groundwater Storage
Construction of up to 16 new recovery and test wells and facilities consisting of chemical treatment equipment, tanks, pumping systems, and associated pipelines.
Bioregional Habitat Restoration
Development of compensation sites to preserve, enhance, restore or establish approximately 2,050 acres of native habitat ranging from ponds and wetlands to serpentine and annual grasslands and coastal oak.
O’Shaughnessy Dam Outlet Works Phase 1
This project addresses deficiencies found in the existing outlet works at O'Shaughnessy Dam.
O’Shaughnessy Dam Access and Drainage Improvements
The key objective of this project is to ensure safe access for Hetch Hetchy Water and Power operators inside the O'Shaughnessy Dam by improving fall protection, access, and drainage.
Bridge Replacement
A condition assessment of the 14 bridges in the care of Hetch Hetchy Water and Power Division identified needed modifications and/or replacements. The current plan includes funding for work two of the bridges: O'Shaughnessy Adit Access Bridge and Lake Eleanor Dam Bridge.
Hetch Hetchy Regional Water System
Two unique features of this system stand out: the drinking water is among the purest in the world; and delivery system of that water is almost entirely gravity fed, requiring almost no fossil fuel consumption to move water from the mountains to your tap.
