2026 General Rate Case (2028-30)

The rates proposed for 2028-2030 will provide customers in the Santa Maria Service Area with long-term value by investing nearly $28 million in local water infrastructure essential to delivering safe, high-quality, and reliable drinking water.

Proposed investments include replacing an aging 85-gallon-per-minute groundwater well in the Sisquoc System, upgrading nitrate, iron, and manganese treatment facilities, replacing a 0.275-million-gallon reservoir in the Cypress Ridge System, drilling a new replacement groundwater well in Orcutt, and modernizing critical pumping and electrical infrastructure across several local water systems. These projects, combined with ongoing pipeline replacements throughout the service area, will improve water quality, strengthen treatment and storage reliability, enhance system resiliency, and help ensure a dependable water supply for local homes and businesses. 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.
