Notice and timing
How delinquency is handled
Grace period after the due date
BWSC adds a delinquency charge to any amount not paid within 31 days after the billing date printed on the water, sewer, and stormwater bill. The separate customer dispute period is 30 days from the billing date. Nonpayment shutoff eligibility is more restrictive than the late-charge trigger: service may be terminated when the bill is at least 60 days past due and the delinquent balance exceeds $250.
Late-fee calculation
The current BWSC residential billing disclosure calculates delinquency at a daily rate of 0.03836%, equivalent to a 14% annual rate, beginning after the 31-day post-billing threshold. Once a formal demand is made, BWSC states that 16% interest applies in lieu of the 14% delinquency charge. A $25 returned-payment fee and the $80 termination-notice fee are separate charges, and foreclosure remedies may be pursued for long-standing property delinquencies.
Disconnection timeline
A monthly bill becomes subject to the delinquency charge after 31 days from its billing date. For nonpayment, BWSC states that service may be terminated once the account is at least 60 days past due and the delinquent balance exceeds $250; the owner must then contact Collections at 617-989-7070, pay all outstanding amounts, and satisfy restoration requirements. The public residential page does not give a single universal day-of-month field-dispatch date after the 60-day threshold, so the posted termination notice and account-specific Collections instructions control. A payment arrangement can prevent interruption when approved and maintained.
