Water-service rates are based on the real costs of treating and delivering water to customers, and are regulated by state public utilities commissions (PUCs).
To determine rates, we work with PUC staffs to study costs of construction, maintenance, operation, administration and financing. Once the studies are complete, the company and PUC present any differing conclusions before an administrative law judge. Based on the judge’s opinion, the PUC sets the water rates.
Rates charged for service may vary based on a customer’s meter size. All customers pay the same rate for water usage. Customers are billed based on a regular meter reading, either monthly or quarterly for residential customers as well as for commercial and other public authority customers.
Rates can vary based on the cost of providing service in each of the communities we serve. Before it reaches your home or business, water is treated through an intricate treating and testing process to help ensure it meets or surpasses rigorous drinking water quality standards.
