Two and a half million people live there and 51 percent of the households have 13 or more people living in them."
"“In Sadr City, when the electricity doesn’t work, the sewage system doesn’t work,” Chiarelli said. “The sewage for two and a half million people, in an infrastructure designed to support 500 thousand people, starts to back up and you end up with places with two feet of standing sewage"
"During its tour in Baghdad, the First Cavalry Division conducted more than 800 civil engineering projects worth $104 million, including more than 70 to restore the city’s electricity. The division built 600 schools and provided $8.3 million in grants to spur the Iraqi economy.
“I did not go over there with the idea of rebuilding the infrastructure of Baghdad. But when we went in and started those projects, things got better,” he said. “When the fighting stopped in the middle of October, we were ready with within seven days to begin $180 million dollars worth of infrastructure projects in Sadr City. We put 20,000 people to work in seven days.”"
