NEW YORK (AP) - Officials say pumps are now working at a New York City wastewater treatment plant that has spilled millions of gallons of raw sewage into the Hudson River.

They're hopeful the discharges will end around 6 p.m. EDT Friday.

Department of Environmental Protection Commissioner Caswell Holloway said the pumps are now handling all of the incoming flow. He says sewage that had been stored in the system is being reduced.

Deputy Mayor Stephen Goldsmith says "heroic work" has been done around the clock to get the Manhattan plant back in service.

The North River Wastewater Treatment Plant was taken offline following a fire in the engine room. Untreated wastewater began flowing into the river beginning at 5:15 p.m. Wednesday.
