GRC 2026 General Case (2028-30)
The rates proposed for 2028-2030 will provide customers in the Calipatria Service Area with long-term value by investing nearly $16 million in local water infrastructure essential to delivering safe, high-quality, and reliable drinking water.
Proposed investments include performing safety improvements at the Holabird Water Treatment Plant’s two 4.5-million-gallon raw water basins and backwash recovery basin, upgrading the 1.03-million-gallon Niland East Reservoir and 1.03-million-gallon Niland West Reservoir, and installing reliability improvements at the Niland Plant, including a permanent generator. These projects, combined with ongoing pipeline replacements throughout the service area, will improve water quality, strengthen system reliability, 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.
