INTRODUCTION
The Hetch Hetchy Water and Power Division under the Water Enterprise (HHWP) is responsible for managing, operating, and maintaining water facilities that are part of the Regional Water System from Hetch Hetchy Reservoir, located in Yosemite National Park, to Alameda East Portal, located in Sunol Valley, and power facilities located from Early Intake Reservoir along the Tuolumne River to the city of Newark. HHWP facilities include three impoundment reservoirs, three regulating reservoirs, four powerhouses, one switchyard, three substations, 170 miles of pipeline and tunnels, almost 50 miles of paved road, over 160 miles of power transmission lines, watershed lands, and right -of-way properties.
HHWP provides 85 percent of the San Francisco Public Utilities Commission (SFPUC) water supply for
2.7 million residential, commercial, and industrial customers in Alameda, Santa Clara, San Mateo, and San Francisco counties. On average, HHWP generates about 1,650 gigawatt hours (GWH) of clean hydro-generated power annually. A majority of HHWP staff is based in Moccasin, CA, which is 140 miles east of San Francisco.
This report provides a quarterly status update on the Hetch Hetchy Capital Improvement Program (HCIP), a group of capital improvement projects that are greater than $5M in value and have been approved by the Commission as part of the SFPUC’s 10-Year Capital Improvement Program. The status of the Hetch Hetchy R&R projects and other programmatic projects not included in the HCIP is reported annually in the Annual Report on Water Enterprise-Managed Capital Improvement Projects.
The map below shows the location of the assets and facilities associated with HHWP.

1 HCIP Quarterly Report | Q4-FY2025-2026 (04/01/26–06/30/26) SECTION 1. PROGRAM DESCRIPTION
The Hetch Hetchy Capital Improvement Program (HCIP) is a group of multi -year capital projects to upgrade existing, aging infrastructure so that it will meet the challenges of today and the future. These projects will deliver improvements that enhance the SFPUC’s ability to provide reliable, affordable, high-quality water to its 2.7 million customers in an environmentally sustainable manner. The goals are 1) to provide capital improvements needed to cost -effectively ensure that water quality, seismic reliability, delivery reliability, and water supply objectives established for the Regional Water System facilities managed by HHWP are met, and 2) to optimize the benefits of HHWP power facilities operations. Ongoing development of the HCIP will sustain the Regional Water System’s status as an unfiltered water source and a gravity-driven system.
The scope of HCIP is divided into three major project types: Water, Power, and Joint. The Water sub - program includes only asset improvements that benefit the SFPUC’s water customers. The Power sub- program includes only asset improvements used to generate environmentally friendly hydroelectric energy. The Joint sub -program includes projects for assets that are used for both water delivery and power generation. In addition, projects in each sub -program of the HCIP have been further organized by asset type consisting of the following:
Water Infrastructure
• Water Conveyance – projects to enhance the reliability of water delivery through pipelines and tunnels, allowing for delivery of water to SFPUC customers. • Water-Only Facilities – projects that benefit water delivery (but not power production) such as water quality protection and improvement projects.
Power Infrastructure
• Powerhouse – projects to improve facilities at the Holm, Kirkwood, and Moccasin powerhouses.
• Switchyard & Substations – projects to meet operational objectives for power, including reliability, regulatory compliance, and sustainability. • Transmission Lines – projects to expand or improve power assets for electricity transmission.
• Power-Only Facilities – other projects that benefit power production and transmission (but not water) such as Cherry-Eleanor Pump Station.
Joint (Water and Power) Infrastructure
• Dams & Reservoirs – projects to improve assets used for storage and delivery of water to SFPUC customers, as well as for water storage for power generation. • Mountain Tunnel – projects to address deficiencies with the Mountain Tunnel, a critical, non- redundant link in the Hetch Hetchy and Regional Water System that conveys water from Kirkwood Powerhouse to Priest Reservoir.
• Roads & Bridges – projects to replace or improve roads and bridges that are utilized to access HHWP assets.
• Utilities – projects to expand or improve utilities for asset and work locations such as water and wastewater treatment facilities.
• Buildings – projects to provide safe and code compliant workspaces.
2 HCIP Quarterly Report | Q4-FY2025-2026 (04/01/26–06/30/26) SECTION 2. PROGRAM STATUS
This Quarterly Report presents the progress made on HCIP between April 1, 2026 and June 30, 2026.
This document serves as the fourth Quarterly Report in Fiscal Year 2025 -2026 (FY26) published for the HCIP.
This quarterly report includes all HCIP projects in the Hetch Hetchy Water Capital Improvement Program according to the 10 -Year Capital Plan for FY2024 -25 to FY2033 -34 (FY25 -34 CIP), presented to and adopted by the Commission on February 13, 2024, under Resolution No. 24 -0032 (2024 HCIP). The 2024 HCIP is a subset of the Hetch Hetchy Water 10 -Year CIP for FY2025 -2034 and includes individual projects over $5 million that were then currently active or intended to be active by July 1, 2024 at the time proposed to the Commission on February 13, 2024. This baseline for comparison will remain the same until adoption of a new 10 -Year CIP; the baseline will be updated with the changes in the adopted CIP at the start of the new fiscal year following adoption. As part of the mid-cycle update to the 10 -Year Capital Plan for FY2025 -26 to FY2034 -35 that was adopted by the Commission on February 11, 2025, none of the 22 HCIP project budgets or schedules were changed from the 2024 HCIP.
The proposed 10 Year Capital Plan for FY2026 -27 to FY2035-36 (FY27-36 CIP) was presented to the SFPUC Commission in a series of budget hearings during the months of January and February, including revisions to projects’ scopes, schedules and budgets. On February 10, 2026, under Resolution No. 26 -0022 the Commission adopted the FY27 -36 CIP. The revised scopes, schedules and budgets that were adopted will continue to be shown in this quarterly report as forecasts and variances through th is fourth quarter of FY25 -26. During the first quarter of FY26 -27 (July 1 to September 30, 2026), these project revisions will be shown as the new program baseline.
There are 22 projects in the 2024 HCIP together with three project development (PD) accounts for program-level expenditures for each of the Water, Power, and Joint Programs. A description of each project and of each project development account is provided in the Appendix A of this report.
The accrued PD expenditures are included in the Cost Summary in Table 3 in order to give an accurate report of the overall HCIP cost performance.
Table 2.1 below shows the number of projects and total project value in each phase of the program based on the Current Approved Budget for all 22 projects as of June 30, 2026 (PD accounts do not have phases and are not included in Table 2.1).

Water Infrastructure
10035575 SJPL Valve and Safe Entry Improvement
San Joaquin Pipeline (SJPL) Nos. 1, 2, and 3 consist of three parallel transmission pipelines (completed in 1932, 1953, and 1968, respectively) that cross the San Joaquin Valley from the east of Foothill Tunnel at Oakdale Portal to the west of Coast Range Tunnel at Tesla Portal, a distance of approximately 48 miles. A fourth partial pipeline (SJPL 4 completed in 2012) consists of a 6.4-mile segment of pipe downstream of Oakdale and another 11-m ile segment upstream of Tesla Portal.
SJPLs deliver Tuolumne River water to the San Francisco Bay Area. They have been in service ranging from 11 to 91 years. SFPUC staff members and contractors need to enter the pipelines regularly to perform condition assessment, maintenance, and repair work. A recent hydraulic study shows that several of the existing valves in the SJPLs may be under -rated for the potential surge pressures that could be triggered from an unplanned closure of the valves at the downstream Tesla Ultraviolet Treatment Facility. For safety reasons, the SFPUC initiated this capital project to increase the pressure rating of the valves, provide safe pipeline isolations for personnel entry into the pipelines, and allow shutdown of any section of the SJPLs without a complete system shutdown. 10014072 HHW- Water Project Development
The Project Development (PD) Account captures Program -level expenditures. The project provides programmatic support for Water funded capital projects. The following charges are allocated to the PD Account: 1) task orders for overall program management and project prioritization tasks, where the costs should be distributed over all CIP Projects; 2) infrastructure and Hetch Hetchy staff performing program-level tasks, including capital plan development, budget management (including fund management and cost reallocations), and unifier and quarterly report generation tasks, where the costs should be distributed over all CIP Projects; 3) portal support for the existing SharePoint Portal (including document management and project dashboard reporting); 4) work outreach program; and 5) City Attorney charges for contract development.
10041725 SJPL Valve Remote Control and Monitoring

Joint Infrastructure
10014088 Moccasin Penstock Rehabilitation
In order to meet the established level of service, mitigate potential risks, and avoid potential consequences of failure, SFPUC is considering replacing the penstocks so that the life of the asset will be extended for another 75 to 100 years. Based on a preliminary study, a combination of a drop shaft, a tunnel and above grade pipes appears to be a favorable alternative. SFPUC will continue the study before determining the most appropriate alternative solution. For capital planning purposes, SFPUC assumes the alternative will include the following major elements: • A drop shaft of about 850 feet deep, • A new tunnel penstock of about 3,100 feet, and • A two 72 in. above-grade penstocks with a total length of 3,000 feet.
10039680 Moccasin Engineering and Records Building
HHWP Project operations and administration is located in Moccasin, California, with facilities including buildings, office trailers, warehouses, shops, laboratories, and sheds. Many existing facilities are deteriorating, do not meet current building codes, and are incurring increased maintenance costs.
HHWP needs to invest in new facilities to meet all applicable codes and standards; reduce maintenance costs; increase employee interconnectivity and productivity; properly store all staff, materials, records, and equipment; and meet energy -efficiency standards. HHWP prepared a report titled "Moccasin Facilities Upgrade Project – Alternatives Analysis and Evaluation Report Update". The report identified long-term needs for creating adequate office space for current staff in Moccasin. In addition, the report evaluated the needs for new, dedicated materials storage space, new records and archives space with offices, new space for servers, and parking space for staff. The Moccasin Engineering and Records Building project will address the need for permanent office space by constructing a new two-story building. Hetch Hetchy and Infrastructure staff are currently located in
A4 Appendices | HCIP Quarterly Report | Q4-FY2025-2026 (04/01/26 - 06/30/26) temporary trailers that have exceeded their useful life. The new building will provide office space for Hetch Hetchy Engineering, Records, Energy Services, Infrastructure, and ITS staff. The scope also includes a secure server room, parking lot, and archive/records storage. The budget and schedule for the project will be modified to provide permanent office space for both Hetch Hetchy and Infrastructure staff and to address escalation since the completion of the 2020 Alternatives Analysis Report estimate. 10041727 Moccasin Warehouse Building
The Moccasin Old Powerhouse was constructed in 1926 and abandoned in the 1960s. The building has multiple structural and nonstructural issues, including cracks, spalling of structural concrete, water intrusion, broken windows, settlement, hazardous materials, and seismic deficiencies. The building is currently used for storage of large equipment and critical spares for the Hetch Hetchy Water and Power system. As a result of the multiple issues, it was determined to demolish the building. A new warehouse is therefore necessary for the storage of the large equipment and critical spares for the Hetch Hetchy Water and Power system that was previously stored in the Moccasin Old Powerhouse. This project includes a construction of a new 9,000-square-foot warehouse within the Moccasin campus to store large equipment and critical spare components for the Hetch Hetchy Water and Power System. The building will include office space for warehouse staff including records retention for warehouse and materials documentation.
10032903 O'Shaughnessy Dam Outlet Works Phase 1
O'Shaughnessy Dam was completed in 1923 and raised in 1938. A condition assessment of the dam outlet works revealed the need for improvements to the existing outlet works, including gates and valves (1923 construction), to ensure safe and reliable operation. Based on engineering studies and prioritization of asset condition, needs, and risks, improvements to the existing outlet works will be implemented in two phases. Funding for this project will include work under Phase 1. Phase 2 of the O'Shaughnessy Dam Outlet Improvement Project begins in 2025. Work under Phase 1 will include: (1) replacement of two existing instream flow release valves; (2) improvements to access and drainage in the dam gallery and stairs; (3) installation of new bulkheads for the outlet intake; and (4) a planning phase and scoping for the slide gates and drum gates improvements. 10037351 Moccasin Dam & Reservoir Long Term Improvement A heavy storm event in 2018 caused significant damage to the auxiliary spillway, upstream trash rack and diversion, and downstream area. Subsequent engineering studies concluded that improvements are needed to increase the spillway capacity to safely pass the updated design flood without overtopping the existing embankment dam. This project is needed for dam safety. This project will construct a new concrete spillway with adequate flow capacity along the alignment of the existing auxiliary spillway and additional flood protection to the Moccasin project facilities.
A5 Appendices | HCIP Quarterly Report | Q4-FY2025-2026 (04/01/26 - 06/30/26) 10014115 Cherry Dam Spillway - Short Term Improvements
Cherry Dam Spillway is a 334-foot-wide ogee-type concrete weir that discharges into an unlined adjacent channel. The spillway capacity is designed for 52,000 cfs. A spill of 1,500 cfs in 2010 resulted in significant erosion damage to the unlined spill channel, large-scale erosion along the western segment of Cherry Dam, and flooding of Cherry Power Tunnel Adit and a campground downstream.
Engineering studies showed that remedial measures and erosion protection for the spill channel are needed to ensure that spill flows from Cherry Valley Dam spillway can be contained without erosion damage to the existing embankment dam and downstream area. Studies also found that long-term improvement to the spillway is needed to increase the hydraulic capacity of the spillway to safely pass the design flood. This project is a short-term interim solution until the long-term spillway improvements are implemented. This project will reestablish containment for the breached spill channel section from the 2010 spill and install armoring to protect the upper spill channel section against erosion from spillway releases of up to 2,000 cubic feet per second. 10030759 Eleanor Dam Rehabilitation
Mitigation alternatives will include improvements to increase spill capacity to safely pass the design flood, installation of a liner on the upstream face of the dam, concrete repairs, valve replacement, and installation of concrete lining and riprap for foundation armoring, and replacement of the existing bridge. 10039119 Early Intake Dam - Long Term
Remove the existing deteriorated dam and construct a new concrete diversion structure and conveyance system within the existing Raker Act boundary to divert flows from Cherry Creek and Tuolumne River upstream of Kirkwood Powerhouse into Mountain Tunnel for SFPUC customers during emergencies.
10014114 Mountain Tunnel Improvement Project
Constructed between 1917 and 1925, Mountain Tunnel (MT) is a critical, nonredundant link in the Hetch Hetchy Regional Water System, conveying SFPUC water supply from Kirkwood Powerhouse to Priest Reservoir. Due to the tunnel's 90 years of operation, deferred maintenance, and construction deficiencies from the early 1900s, sections of the tunnel have deteriorated, some more extensively than others. The Mountain Tunnel Inspection and Repairs Project provided a tunnel inspection in 2017 to update the Condition Assessment conducted in 2008. Short-term repairs were also made in 2017 and 2018 to reduce the risk of failures in the concrete lining prior to implementation of the long-term project.
The Mountain Tunnel Improvements (Rehabilitation)Project was selected for the design and construction of the preferred engineering alternative that will keep this vital component of the Hetch Hetchy Regional Water System in reliable service for years to come. The budget and schedule are based on the Mountain Tunnel Improvements Project construction phase, which is anticipated to take place between 2021 and 2027. This is the water funded portion of the Mountain Tunnel projects. For the Mountain Tunnel Improvements Project, the water portion will rehabilitate the inside of the tunnel and extend the siphon at South Fork, along with related safety improvements to the roadways that access the Mountain Tunnel.
