January 10, 1983: New York Times headline—Repair of Plant Ends Dumping of Raw Sewage. “The Wards Island sewage treatment plant, disabled when a huge valve burst six days ago, was back in operation yesterday, ending the daily discharge of 300 million gallons of raw sewage into the Harlem, Hudson and East Rivers.
The city had been forced to divert the sewage from the plant after a ”cone check valve” cracked at 8:30 P.M. on Tuesday, sent a 12-foot jet of water into the air and caused the flooding of the plant’s six main motors….
The total cost of fixing the plant will be about $330,000, according to John Cunningham, a spokesman for the city’s Department of Environmental Protection….
‘All the charts, the records, the work schedules went by the wayside,’ said Fred DiSisto, an operating engineer with the plant for 20 years. ‘We operated out of the kitchen. It kind of turned into a holiday atmosphere. Everybody was all pumped up. It broke the routine around here.’
Some of the men at the plant estimate that 50 pounds of coffee were consumed in the kitchen in the last four days. Men slept there, too, as 12-hour shifts were the norm.
Officials have not yet determined what caused the cone check valve to burst. The valve is made of cast iron and is 48 inches in diameter. It was installed six years ago, when the 45-year-old plant was upgraded.
‘We are still doing some tests to find out why the valve broke,’ said Mr. Cunningham. ‘The valve should have lasted 40 years.’ The valve is one of six that keeps the waste water in the plant’s treatment tanks from flowing back into the plant’s main pumping gallery. When it burst, the water came back into the gallery and then overflowed onto the plant’s motors. Released Into Rivers
The sewage had to be released into the Hudson, Harlem and East Rivers from 52 regulators in Manhattan and 36 regulators in the Bronx to avoid a backup at the plant and the eventual flooding of homes, officials said.”
