SAN JOSE, CALIF., January 24, 2024 – San Jose Water (“SJW” or “the Company”), a wholly owned subsidiary of SJW Group (NYSE: SJW), is proud to share a year of significant advancements and milestones in water management and customer service.

“We have maintained a long tradition of delivering safe and reliable water service while ensuring that we protect and preserve our environment,” said SJW Group Chair, President and CEO Eric W. Thornburg. “Water touches everything important to us including public health, fire protection, and economic development.”

Highlights of 2023 include:

• Investing in our Community: $150 Million in capital improvement projects were completed — ensuring continued safe, reliable, and efficient water service to our customers.
• Innovative Leak Detection Program: SJW’s advanced leak detection program proved a resounding success, saving an impressive 717.4 million gallons of water in 2023 — contributing significantly to water conservation efforts.
• Fleet Modernization: In 2023, SJW’s fleet included more than 24 electric vehicles and 30 ChargePoint charging stations.
