Tahoe City PUD projects 20% demand drop by 2030 amid major metering and reconstruction push
Tahoe City Public Utility District, California · Meeting date: June 18, 2026 · Published: June 19, 2026
The California utility has adopted its 2025 Urban Water Management Plan, forecasting a significant dip in water demand driven by the ongoing rebuild of four unmetered systems, while a newly online regional treatment plant provides a 900-million-gallon supply surplus.
Key points
- TCPUD adopted its 2025 Urban Water Management Plan, projecting a 20% reduction in water demand by 2030 as legacy systems are fully metered.
- The Madden Creek water system will be fully rebuilt and metered by the end of 2026, followed by the Tahoe Cedars, Tahoe Swiss Village, and Glenridge systems over the next five years.
- The district boasts a projected supply surplus in the 900-million-gallon range, drastically boosted by the recent addition of the West Lake Tahoe Regional Water Treatment Plant.
- The Board set an October 2027 deadline for Phase 1 customer service line relocations for the Tahoe Cedars reconstruction, allocating an estimated $680,000 for customer financial assistance.
Full report
The Tahoe City Public Utility District (TCPUD) Board of Directors formally adopted its 2025 Urban Water Management Plan (UWMP) on June 18, outlining a long-term strategy heavily reliant on system reconstruction and universal metering to drive down demand and curb system leakage.
According to Director of Utilities Dan Lewis, the district's service population is projected to grow modestly from 8,600 in 2025 to 9,100 by 2050. Despite this 6% growth over the next 25 years, the district projects a significant dip in total water demand by 2030.
Lewis attributed the projected demand drop directly to the district's ongoing capital improvement projects targeting unmetered legacy infrastructure. The Madden Creek water system is slated to be fully rebuilt and metered by the end of 2026. The Tahoe Cedars, Tahoe Swiss Village, and Glenridge water systems—the latter two acquired by the district in 2020—will be fully metered over the next five years.
Based on the district's historical experience with metering projects, Lewis confirmed staff anticipates a 20% reduction in water use once the system overhauls are complete, alongside a reduction in system leaks.
On the supply side, the UWMP supply reliability assessment shows TCPUD exceeding demand with comfortable margins through the 2050 planning horizon across all hydrologic conditions. Lewis noted a projected supply surplus in the "900 million gallon range," attributing the drastic increase in water supply to the recent addition of the West Lake Tahoe Regional Water Treatment Plant. Because of this surplus, future groundwater projects—such as new wells planned for the Alpine Peaks and Glenridge systems—will be focused purely on system redundancy and backup supply rather than capacity expansion.
In a related move to advance its metering and reconstruction goals, the board also approved a critical deadline for the Tahoe Cedars Water System Reconstruction Project. The board established an October 15, 2027, deadline for Phase 1 customer service line relocations, which impacts 258 properties.
Director of Engineering Sarah Bussone-Johnson reported that Granite Construction Company, the design-build contractor for the project, anticipates completing Phase 1 construction by the end of the 2026 season.
To ease the burden of private service lateral relocations, the district has established a two-tiered grant program. Bussone-Johnson noted the district anticipates spending approximately $680,000 in 2026 on Phase 1 customer financial assistance. The program offers a baseline $5,000 grant to all affected customers, with up to $12,000 available via reimbursement for Tier 1 rate assistance customers.
