2026 General Rate Case (2028-30)
The rates proposed for 2028-2030 will provide customers in the Simi Valley Service Area with long-term value by investing nearly $32 million in local water infrastructure essential to delivering safe, high-quality, and reliable drinking water.
Proposed investments include installing a new inline booster station with two 500-gallon-per-minute pumps to improve service to the Katherine Zone, recoating and upgrading the 1.50-million-gallon Alamo Reservoir, and replacing over 280 service lines throughout the customer service area. These projects, combined with ongoing pipeline replacements throughout the service area, will improve water quality, strengthen system reliability, and extend the life of critical storage 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.
