Erica Kocur said her last bill was for $1,600. The city believes the bill is accurate even though it's 20 times the woman's usual bill.
The city said she must have a running toilet or dripping faucet.
But KSTP-TV said the bill is charging for almost 200,000 gallons of water. That's three times the volume of her entire home.
A shower would have to run nonstop for almost two months to use that much water.
Dripping faucet indeed!
