Provider briefing
How this utility’s billing works
California American Water - Monterey District operates as a private investor-owned utility serving Monterey County / Monterey District. Customers should use the provider’s current account-specific bill and official customer-service instructions as the final authority for deadlines, balances, and service requests.
The published water-rate framework is described as Increasing four-block commodity tiers with a monthly fixed service charge; California American Water also applies district-specific regulatory and supply-related charges and may use conservation or drought mechanisms.. Bills are generated monthly residential billing, and a typical residential cost reference is For a 5/8-inch single-family meter using approximately 7,000 gallons (70 CGL), the 2026 Monterey schedule is approximately $144.81 before any applicable taxes, surcharges, or non-water services: $48.35 monthly service charge plus 30 CGL at $0.8038, 30 CGL at $1.6076, and 10 CGL at $2.4115. CGL is the tariff's 100-gallon unit.. These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.
Wastewater and sewer calculation
California American Water's Monterey water tariff does not establish one universal sewer charge for every Monterey-area customer. Sewer service may be billed by Monterey One Water or a municipality, so wastewater rates, winter averages, and account eligibility must be obtained from the separate sewer provider rather than inferred from the Cal-Am water bill.
Meter and infrastructure notes
California American Water is replacing Monterey meters with advanced metering infrastructure (AMI). The company describes detailed usage and leak information with near-real-time availability, while customers who opt out are charged a $13 monthly fee and a $70 initial opt-out installation charge. The normal AMI installation has no customer charge; billing remains monthly.
