The pipe, which heads to the Yonkers Sewage Treatment Plant, has ruptured eight times in recent years, with a major rupture in August 2012, said Legislator MaryJane Shimsky, the chairwoman of the Infrastructure Committee, at a board meeting Monday.
The 2012 break spilled several million gallons of sewage and prompted a water advisory for the Hudson River.
“This is one of the most important things we’re going to be doing all year,” Shimsky said.
The pipe to be replaced runs from the Tarrytown pump station to Route 119. Shimsky said the county started looking at replacing the pipe in 2005.
