Margarita Garcia has two problems: Too much water — and not enough water. And often at the same time.
On a hot summer day in March, she headed home from her cleaning job and found that her street was flooded with water.
The clouds had broken with more rain than her neighborhood — a slum on the southern outskirts of Buenos Aires — could handle. The water rose to her knees by the time she got to her home, the bottom floor in a four-story slapdash brick building. That morning, she'd set up a blockade using a big wooden board, but it hadn't kept the water from seeping in.
