Notice and timing
How delinquency is handled
Grace period after the due date
A dedicated this detail was not publicly posted. As a universal grace-period number; the company describes delinquency and disconnection in its tariff and customer-service rules rather than publishing one simple statewide residential grace period on the reviewed page.
Late-fee calculation
The reviewed Monterey 2026 customer pages do not expose a single current residential late-fee amount or percentage. Customers should use the bill's tariff line items and contact customer service before the account becomes delinquent; payment arrangements can be available for qualified hardship cases.
Disconnection timeline
A residential account may be disconnected for nonpayment as much as 60 days after it becomes delinquent. California American Water states that written notice is sent at least 10 days before disconnection and that the company attempts telephone contact; contested charges raised within five days of bill receipt are reviewed before shutoff.
