UPDATE: Sewage spill stopped, repair efforts underway

UPDATE 10 a.m.: Work crews have stopped the sewage leak that dumped about 150,000 gallons of raw sewage into the Naugatuck River Thursday night. Now the effort is underway to repair the broken line.

According to Paul Whitmore, a spokesman for Veolia Water, which runs the Seymour sewage treatment facility, the break occurred last night next to an active Metro North railroad crossing near the Kinny Town Dam. The company is still investigating the cause of the break.

“Essentially it was a manhole that caved in,” Whitmore said Friday morning. “Workers were out until late last night and they were able to get the flow stopped.”

According to the Department of Energy and Environmental Protection, the break was leaking at a rate of more than 100 gallons per minute before crews were able to stop it. Workers also attempted to contain the spill, but it is unclear how successful those efforts were.

According to the United States Geological Survey’s National Water Information System, the Naugatuck River is currently flowing about 403 cubic feet per second, or about 3,014 gallons per second. The Naugatuck River merges with the Housatonic River in Derby and then flows south before emptying into the Long Island Sound between Stratford and Milford.

ORIGINAL STORY: According to news reports, thousands of gallons of raw sewage spilled into the Naugatuck River after a siphon carrying the wastewater ruptured on the river’s edge in Seymour.

A spokeswoman for the state Department of Energy and Environmental Protection said Thursday that 100 to 200 gallons of wastewater a minute were flowing into the river.

The Republican-American reports that DEEP spokesperson Cyndy Chanaca says town crews cleaned debris inside the pipe and built a dam of sandbags to contain the spill. The cause is being investigated.
