Recent extensive pipe and valve replacement at the Lower Gate House (powerhouse) at the Wachusett Dam has finally been completed and the Wachusett Aqueduct reactivated.

The final phase of the completed pipe and valve contract included a maximum flow test of the aqueduct.

That’s a lot of water, up to 240 million gallons of water in 2-3 hours, to go down that tunnel. 

John Gregoire of MWRA supervised the test and was kind enough to invite me along.

Here are some of the videos we took from that day all the way from Clinton to Southborough.

I hope you like them.

Thanks,

Paul
