Debris Boom at Chute Bell GS

Debris Boom at Chute Bell GS

In 2004, a Debris Boom was installed at Hydro Quebec's Chute Bell GS, a small hydro generating station near Montebello, Québec.

The purpose of the Debris Boom was to divert or retain the debris as it can accumulate and block the intakes, causing generation losses. PVC pipes were placed underneath the steel pontoons in order to divert and retain the debris. Periodic removal of the debris was not necessary, as it was done naturally. During winter, the ice would freeze into the debris which would break off into large drifts in the spring. These drifts would naturally get flushed downstream during the ice break-up.

The boom has been in service since 2005 with no need for maintenance.
