Another benefit of hydro: plastic debris removed from the river and properly disposed of. These two barrels of waste can be collected in a single day. The wood debris is composted.

The solid concrete dam at Wyre Wynd Hydro (built in the 1920's) was showing some uniform erosion of the downstream surface. Consequently, during 2009 the dam was resurfaced employing a 3-step process: 1) pressure wash old concrete surface, 2) lay reinforcing steel, and 3) shoot approx. 6" thick concrete utilizing Gunite placement process.

September 2009 forebay was drained and stone walls were Gunite finished to eliminate leakage and strengthen walls.

The resurfacing project involved 7 men working 7 weeks, 450 man hours of pressure washing, 242 yards (35 truck loads) of concrete, 2 tons of epoxy coated rebar. Job completed 11/2/09.

The Gunite process consists of dry concrete mix blown through a hose with water introduced at the nozzle. Adding minimal water at the last moment results in zero slump and a very strong finished product.

The Gunite process eliminates the cost of form work that would be necessary with poured concrete.

Duncan smoothes and levels the concrete to minimize erosion from flowing water.

SHI employees, Rick (left) and Bob are identical twins who keep things running smoothly at the hydros. Who do you think is the harder worker on this day?

New timber intake gates and trash rack structure built by SHI for Glen Falls project.

Woodstock, CT High School student Riley S. did a class project on hydropower. In order to understand some of the tasks involved we had her help rake the trash racks!
