Following a prolonged outage due to the ransomware attack, the Baltimore City water bill payment site is finally back online. A notice on the payment site reads as follows:

ALERT: DPW began issuing new water bills on Wednesday, August 7th. New bills will be generated and mailed in batches of 10,000 per day. Your new water bill charges will not appear in the online system until your August bill (including charges for April, May, June and July) is generated and mailed.
