NEW ORLEANS — With debris from last weekend’s flash flood still piled up on sidewalks and their city under a state of emergency, New Orleans residents looked ahead warily on Friday to the prospect of more rain to tax the city’s malfunctioning pump system.

The city scrambled to repair fire-damaged equipment at a power plant and shore up its drainage system less than a week after a flash flood from torrential rain overwhelmed the city’s pumping system and inundated many neighborhoods.

Annie Hutchins says she’s “traumatized” every time she sees clouds in the sky since an Aug. 5 flood. She had to walk through knee-high water to get to her house in the Treme neighborhood.

“It’s a little bit unnerving that we were told everything was working, and the next day the story was a little bit different, and then the next day the story was a lot different,” she said. “I’m the kind of person that trusts anyone until they prove otherwise. So, I don’t feel like I have a lot of reason to trust what I’m being told anymore.”

A control panel on one of two working turbines had been fixed by Friday morning, but the system remains well below full power, Mayor Mitch Landrieu said at a morning news conference. The turbine powers some of the city’s pumps.

“We remain at risk until additional turbines are back up,” Landrieu said, adding that he hopes that will happen by the end of the month. Still, he said, “Panic is not where we need to be right now.”

He said the latest to go offline will be powered up over 24 hours. Meanwhile, Landrieu said, 26 generators have been ordered and will remain through hurricane season.

He also said a location was being set up Friday for residents to get sandbags should they want to take the extra precaution of sandbagging their homes.

Schools closed for the week, and the mayor urged residents to park their cars on high ground.

Gov. John Bel Edwards described his emergency declaration Thursday as a precautionary measure.

The National Weather Service forecast a 60 percent chance of rain Friday, primarily during the late morning and afternoon, with a chance that heavy rainfall could lead to more flooding.

The city’s infrastructure had been crumbling for years before the devastation unleashed in 2005 by levee breaches in Hurricane Katrina’s aftermath. The federal government earmarked billions of dollars for repairs and upgrades after the hurricane, but the problems have persisted.

Streets are pockmarked with potholes and sinkholes. The city’s water system has been plagued by leaks from broken pipes and power outages leading to boil water advisories.

New Orleans’ municipal pumping system is supposed to move water out of the low-lying city. Having the system crippled in August, the middle of hurricane season, could not come at a worse time for New Orleans.

“With great prayer and a lot of hard work, hopefully we’ll be OK,” the mayor said.

But officials feared that even a common thunderstorm would test the system’s reduced capacity.
