Summit Metal Fabricators was contracted by Algonquin Power to repair and replace gates and a surge tower (penstock) at their hydro-electric dam in Milton, NH.

Summit Metal Fabricators designed, fabricated and installed head gates, waste gates and a surge tower based on drawings supplied by Algonquin. The surge tower was fabricated from galvanized steel, 35 feet tall and 8 feet across. On-site welding repairs on fire line pipes (10” and 36”) were performed as well.

The head gates were fabricated to exact tolerances and were equipped with brass fittings and bushings.

All components were fabricated at the Summit shop and transported and installed at the Milton, NH dam.
