MAC & MAC Hydrodemolition has completed corrective maintenance on the pipeline at Run Of River Power's Brandywine Creek hydroelectric generating facility near Whistler, British Columbia, Canada.

Harmful iron reducing bacteria was successfully cleaned from the interior walls of the steel portion of the penstock route leading to the power house. It was then coated to protect it from future occurrences of such bacteria.

Preliminary test results indicate that plant output should increase due to a significant reduction in friction as a result of cleaning and coating the penstock.
