James Neiss/staff photographer UNDER REPAIR: Crews repair the four main pumps at the Niagara Falls Wastewater Treatment plant after they were shut down by rising storm waters Friday night. Pump components had to be removed and sent out for inspection and repaired. Local and state officials toured the plant on Wednesday to get a better idea of the damage. Millions of gallons of untreated sewage continue to flow into the Niagara River. Paul Drof, the water board's director, said that crews have been working around the clock since severe storms knocked out filtering equipment Friday night in an effort to restore water treatment services for the city. He expects that to be done by Friday. Initial cost estimates for the damage caused by the storm to water board equipment ranged from $500,000 to $5 million.
