The Water Revenue Bureau billed him $758.09 in July for the sealed house. That swelled to $940.54 in August.
The 36-year-old Lang received the first bills for each after owning the properties for more than two peaceful years, during which there was not even a drop from the Water Revenue Bureau. Then, came the flood.
When he got the bills, he was shocked. When he showed them to me, I was stunned. When I revealed them to Department of Revenue spokeswoman Vicki Riley, she was - well, she had to look into it, but was clearly surprised about a water bill flowing from a vacant lot. The Water Revenue Bureau is a division of Revenue.
When he received the July bill, Lang says, he put it aside, because, "I sort of figured it was a mistake so wasn't too concerned about it." Shrugging it off, he didn't notify the Water Revenue Bureau.
You know what's coming next.
In August, new bills - with late fees - came pouring in.
Lang got a new attitude.
He went to the Water Revenue Board in the Municipal Services Building and reported the issue. He was told an investigator would go out within the next 30 days to see what had happened.
While waiting, Lang contacted me.
I contacted Riley.
While we wait for Riley to dig up answers to some of my questions, let's reflect on other things that routinely go wrong in the age of technology.
I wrote about Deborah Stagg, who was billed $12,000 by PGW. The proper bill should have been $2,200.
Brian Yan got ticketed for overtime parking by the Parking Authority in a spot he had just pulled into.
Afghanistan war veteran Joe Howe was hit with a late charge for not paying a state tax bill on time, a bill he was exempt from paying because he was out of the country (and in the Marines).
This is stuff I have written about in just the last two months. Other columnists and reporters have had their share.
We know nothing's perfect, but no wonder so many people don't trust government. Can't anybody do anything right any more? Do they care when they don't?
Rant over, I feel better. Back to work.
The Water Revenue Bureau found out only in April the property had changed hands, Riley says. I didn't get an answer on why it took the city two years to alert Revenue.
But the biggie is this: How could Lang get a water bill for a vacant lot that has no building, no water service and no meter? The response was double-talk.
Bottom line, Riley tells me, "the bill has been adjusted and the new owner will receive a new bill in the mail."
If it's not in the right amount, I'll be back to blow up the dam.
