Notice and timing
How delinquency is handled
Grace period after the due date
0 days are stated as a general grace period: the bill’s printed due date controls, and DEP says late-payment charges apply to delinquent charges. Special rules can suspend late charges for 90 days on certain AMR catch-up bills, and DEP may adjust a due date in specified escrow or retroactive-billing situations; those exceptions are not a universal grace period.
Late-fee calculation
DEP assesses late-payment charges on delinquent charges, fees, dishonored-payment charges, and prior late charges. The current DEP billing page lists annualized interest of 6% for properties with billable assessed value of $250,000 or less (or qualifying cooperatives at or below $250,000 per unit), 9% for values above $250,000 through $450,000, and 16% above $450,000; the applicable annual rate is used to calculate late interest on the outstanding balance. The Water Board rate schedule also provides special suspension or due-date rules for qualifying catch-up and retroactive bills.
Disconnection timeline
DEP’s current public notice says a water shut-off notice may be issued when a delinquent account balance has remained unpaid for more than one year. The enforcement progression is: chronic delinquency and prior written warning; a Water Shut Off Notice gives the date by which full payment or a qualifying payment-agreement down payment must be received; if the deadline passes, service may be terminated; restoration requires the entire account balance or an approved payment agreement with at least a 25% down payment, plus the $1,000 termination fee. DEP does not publish a universal calendar day from the original bill due date because notice timing and account type control the schedule.
