The wrong due date was printed on about 15,000 recent water bills of Baltimore County residents, officials said Friday.
The bills had a due date of Friday. Bills are actually due 21 days after they are received.
Officials with the Baltimore Department of Public Works said Friday that the mistake happened because of an issue with “internal coding” that was used to extend a forgiveness period granted after a ransomware attack in May on city computers.
County residents receive their water from the city system.
