Aug. 7 (UPI) -- While New Orleans' water pump stations are operating and pumping water from the weekend's floods, exit ramps remain closed and officials warned of more potential trouble Monday.
Between 8 and 10 inches of rain fell in about three hours on Saturday, and while the city's 24 pumping stations were overwhelmed, they continued working, the Sewerage and Water Board said.
Damage from flooding was reported across New Orleans. The city's police, fire and medical services agencies responded to more than 200 flood-related emergency calls.
City council members questioned the efficiency of the pumping operations, and will hold an open meeting on Tuesday to discuss the matter.
"There is no drainage system in the world that can handle that [rate] immediately," Sewerage and Water Board Director Cedric Grant said. "It's pretty amazing that it can do one inch of rain in the first hour and a half an inch an hour after that. We are dealing with 8 to 10 inches of rain in three hours. It is not going to be able to pump that in an hour."
Four exit ramps of Interstate 10 and Interstate 610 remained closed Monday morning because of excess water, the state's Department of Transportation and Development said.
More rain is forecast for Monday. Ryan Berni, deputy mayor for external affairs, said a more formal evaluation of damage, including the possibility of a request of an emergency declaration, will be made after the rains pass.
