San Jose Water files for rate increase to fund $540 million water infrastructure investment
(UI) – San Jose Water (SJW), a wholly-owned subsidiary of SJW Group, announced the filing of its 2024 General Rate Case (GRC) application with the California Public Utilities Commission (CPUC) for new rates in 2025, 2026 and 2027.

The application proposes a three-year, $540 million capital investment program to ensure a resilient water system for SJW customers and its local communities. SJW provides water service to approximately one million people in the greater San Jose metropolitan area.
The company has served customers since 1866, and its infrastructure requires continuous replacement before it reaches the end of its service life. Since 2005, San Jose Water has invested more than $1.6 billion to upgrade water infrastructure — ensuring the continued delivery of high-quality and reliable water service.
Some of the projects proposed for completion during the period covered by the GRC include:
- Replacing about 24 miles of water mains annually
- Addressing PFAS-impacted groundwater wells to protect public health
- Expanding the non-potable recycled water system to improve water supply reliability
- Strengthening the physical security of the water system and enhancing readiness to deliver safe and reliable water service during power interruptions, earthquakes and wildfires
- Advancing the CPUC’s Environmental and Social Justice Action Plan by improving access to high-quality water service, increasing climate resiliency, and promoting economic and workforce development opportunities.
Founded in 1866, San Jose Water is an investor-owned public utility, and is one of the largest and most technically-sophisticated urban water systems in the United States. San Jose Water also provides services to other utilities including operations and maintenance, billing, and backflow testing.
San Jose Water is owned by SJW Group. SJW Group also owns: Connecticut Water Company in Connecticut; Maine Water Company in Maine; and SJWTX, Inc. (dba Texas Water Company) in Texas.
“Water remains one of the most critical resources that we rely on in our daily lives,” said John Tang, Vice President of Regulatory Affairs at SJW. “Reliable water service is not only essential for day-to-day function, but also supports fire protection, economic vibrancy, and environmental conservation efforts. Thoughtful and consistent capital expenditures are necessary to ensure clean drinking water and a healthy, natural environment.”
