Notice and timing
How delinquency is handled
Grace period after the due date
30 days from the bill date before the bill is due; this is the published payment period rather than necessarily a penalty-free post-due grace period.
Late-fee calculation
The reviewed Cambridge page did not expose a single current percentage or fixed late fee; past-due water/sewer charges are subject to City collection rules and Massachusetts statutory interest provisions where applicable.
Disconnection timeline
A dedicated this detail was not publicly posted. The reviewed public page did not publish one universal day-by-day physical shutoff calendar.
