Up until October, the Walters family lived in a yellow two-story home on the south side of Flint. A couple of red maple trees shade the tiny front yard.

Walters heads to the back of the house, in a small room off of the kitchen, where the family keeps its stockpile of bottled water.

“This is our water stash. Once a week we go and we fill 40 gallons of water, so we have water to drink with, to cook with, and to bathe Gavin and Garrett in,” says Lee Anne Walters.
