"Meanwhile, I had been clicking all around on the water company’s website, and I found a 400-page PDF document that was a list of account numbers of people who owed money that the water company supposedly couldn’t deliver bills to by mail. We took one of the account numbers and plugged it into the utility company’s website, and it showed a lot of information: How much was owed, consumption history, payment history. And there was a payment button. "

Surprised that information was out in the open, I don't think it should have been. Props to her to make something good out of it. It's also quite strange that the water company would be able to deliver water but the postal service can't deliver mail. Both appear to be tied to the same physical location.
