Crews repair broken water main; service restored

NASHUA – After a 12-inch water main broke Tuesday evening in the area of Chestnut and Kinsley streets, causing a deluge through the neighborhood, crews worked throughout Wednesday to repair the damage.

Nashua Director of Emergency Management Justin Kates said most of the issues were corrected by early Wednesday.

Pennichuck Corp. Chief Operations Officer Donald Ware said nine water connections in the area were out of service, but that they are now back up and running for those customers.

Ware said officials on Tuesday were replacing a water main in the area when one of the lines intended for replacement failed.

“I think the reason it failed is it was a 100-plus year-old water main,” Ware said.

Ware said the main was held together with compacted soil, providing some structural strength against the water pressure inside the old line. When crews removed that soil – in order to excavate down and put the new water main on top of the old one – the compacted soil allowed the old cast iron pipe to finally break.

The resulting cavernous hole will be filled with compacted materials including soils and gravel.

It should soon be repaved and repaired.

“In the process, their next step was going to be to connect a new main on Kinsley (Street) to the new main on Chestnut (Street),” Ware said. “Right where that connection was going to be made is where the old main on Chestnut Street failed.”
