GRC 2026 General Case (2028-30)
The rates proposed for 2028-2030 will provide customers in the Clearlake Service Area with long-term value by investing over $6.5 million in local water infrastructure essential to delivering safe, high-quality, and reliable drinking water.
Proposed investments include replacing the aging Oakcrest Booster Pump Station with a new fire-hardened facility and replacing filter media in a critical treatment filter at the Sonoma Water Treatment Plant. These projects, combined with ongoing pipeline replacements throughout the service area, will improve water quality, strengthen system reliability, help protect local groundwater resources, and extend the life of critical water infrastructure. Together with the company’s ongoing investments in water treatment technology and fire hydrants that support public safety, new investments will help maintain safe drinking water standards and reliable service for the community.
