If you live in New England or New York State you've likely already driven on our roads, crossed over our dams, biked on our recreation paths, sent your recycling and trash to our facilities, used water that we helped treat, and powered your homes with electricity from our energy projects.

“I especially appreciated your efforts in coming up with solutions when the site conditions didn’t exactly agree with the drawings. Together we have created a new power plant that we can all be proud of.”
