Some 20,000 Detroit water customers could have their water shut off starting Tuesday.
That's how many are behind on their bills, according to the city.
In Detroit, the average monthly water bill is $75. The average past due amount? $633.
All those unpaid bills add up: Last March, the city was owed some $47 million in past-due residential bills – though a department spokesperson said they’re not sure what the current amount owed is, because so many people are currently making payments to avoid shutoffs.
