Preserving 100 Years of Hydroelectric Generation Service

Durocher Marine relines the upper section of 7,000 feet of Cloverland Electric’s Power Canal Bank with precast concrete retaining wall units.

Inside the Project

Cloverland Electric’s Power Canal in Sault Ste. Marie Michigan was built over 100 years ago. Durocher Marine was hired to repair 3,800 ft of the canal with precast concrete units that form a new wall. First the existing wall and fill are removed to the top of the existing timber pile bent structure. Then the concrete units are placed side to side along the top of the timber canal structure and backfilled. Access in the canal is severely limited due to the Head Gates at the entrance of the canal, 9 bridges, and the Powerhouse. Working time is also restricted due to peak summer electricity demand in July and August. Working time is also restricted by winter conditions in the Northern climate. Expected completion Fall 2017.

Why it matters

This work is very challenging, but very necessary to the owner. Our crews work around weather conditions and Peak Power demands to rehabilitate a landmark structure that has been in service for over 100 years. Helping the Owner keep the canal operational and functional for the next 100.
