Hawaii regulator approves $1.94M rate rise for Kapalua water and wastewater systems

The Hawaii Public Utilities Commission (HPUC) has approved a settlement allowing Hawaii Water Service to raise annual revenue by about $1.94 million for its Kapalua water and wastewater systems. Hawaii Water is a subsidiary of California Water Service Group. The increase includes nearly $1.47 million for water and more than $469,000 for wastewater. It covers $5.86 million in capital improvements, including upgraded water storage, new valves, backup generators and replaced pumps. It also reflects higher costs, including about $1.7 million a year for purchased water, labour and inflation. Purchased water costs pass directly to customers. This is the first general rate increase for the systems since Hawaii Water acquired them in 2021. New rates take effect this month.

California Water Service hits record $147M quarterly capex as rate case win unlocks revenue growth

California Water Service Group reported second-quarter 2026 sales of $308.6 million and net income of $56.47 million, alongside its 326th consecutive quarterly dividend of $0.335 per share. The company achieved record infrastructure investment of $147 million in the quarter. The favourable resolution of the 2024 California General Rate Case enabled meaningful rate adjustments and new revenue stabilisation mechanisms. The company's narrative projects $1.3 billion revenue and $205.8 million earnings by 2029, requiring 7.5% yearly revenue growth. Community fair value estimates for the utility span from $40.05 to $51.67 across different assessments. The rate case decision provides clearer revenue visibility, though rising capital and PFAS-related costs remain a key risk if they outpace regulatory relief over time.
