The failure of a 24-inch force main near the Cos Cob rail station caused a knee-high flood of wastewater this morning on Sound Shore Drive.
The broken line, which is believed to have ruptured around 9 a.m., services properties in neighborhoods east of the Mianus River; Cos Cob, Riverside, North Mianus and Old Greenwich, town officials said."This is a major burst," said First Selectman Peter Tesei. He was uncertain how many residents would be affected.
Tesei issued a reverse 911 call to affected areas this morning notifying households of the disruption and asking residents to curtail their use of wastewater-producing appliances, such as toilets and dishwashers.
Doing so will reduce the flow of wastewater through the broken pipe and allow crews to reach it more effectively to begin repair work.The disruption does not affect the drinking water supply and unlikely to cause backups for residents, said Amy Siebert, Commissioner of Public Works.

The town's Department of Public Works will be working through the night and into the weekend to get the Old Greenwich Force Main, which conveys wastewater from Old Greenwich, Riverside, North Mianus and Cos Cob, back to service. The main broke at Sound Shore Drive, in front of the Cos Cob Power Plant, earlier today. The nature of the break is not know, a department release said.
This force main conveys flows from the Old Greenwich, Chapel Lane and Cos Cob pump stations. Fred Durante Jr., Inc. will be providing force main repair services. Each of the three pump stations will be set up to bypass flows, allowing the team to excavate and repair the affected pipe section. Specialty equipment is also being provided by Godwin Pumps of Bozrah.
The first selectman has declared an emergency to allow the town to rapidly address this issue. As residents near the three pump stations may hear equipment and staff working throughout this emergency, Sewer Department officials are urging patience. Repair crews, lights and equipment will be working around the clock on Sound Shore Drive.
All utilities in the area have been contacted and are coordinating with the town’s repair team. Aquarion Water Company is managing its potable water system to maintain its integrity at all times. The town has used its Reverse 911 system to reach out to residents, asking those in Old Greenwich, Riverside, North Mianus and Cos Cob to conserve water. This will help minimize flow to these pump stations while these repairs are conducted.
