The town also agreed to rehabilitate a critical wastewater collection system that serves three of the town’s major wastewater pump stations.
The agreement settles allegations of Clean Water Act violations by the town stemming from two major ruptures of the town’s sewage system.
The US Environmental Protection Agency said on 14 October 2005, the town’s Old Greenwich Common Force Main ruptured and released 14.5 million gallons of raw sewage into the Cos Cob Harbor, a tributary to the Long Island Sound.
The same force main ruptured again on 16 Dec 2008, releasing 28 million gallons of raw sewage into Cos Cob Harbor.
Under the settlement, the town will replace the section of the force main which previously failed, and will also evaluate the need to replace other sections of the force main that have not been replaced in the past.
