JOHANNESBURG — Lungile Khoza is at her wits' end. The mother of four has been without water at her home for three weeks, the kids are dehydrated and sick, and she can't run her small hair salon so she's losing money.

Khoza, 37, lives in Soweto, a sprawling township of Johannesburg, which is among the areas worst hit by a water crisis in the city. She says there are sometimes government trucks distributing water, but it often runs out before you make it to the front of the line.
