Notice and timing
How delinquency is handled
Grace period after the due date
45 days from the billing date; the City states that interest charges begin if payment is not received by the 45th day.
Late-fee calculation
Interest begins when payment has not been received by the 45th day after the billing date. The reviewed public pages do not state the interest percentage, compounding rule, returned-payment fee, or any additional collection charge.
Disconnection timeline
A dedicated this detail was not publicly posted. Somerville publishes the 45-day due-date/interest trigger but the reviewed pages do not state the exact calendar progression from delinquency through notice to physical termination of water service.
