The runner buckets of one of the runners were severely worn after about 6 months of operation due to the sediment in the water.  All buckets were repaired by building up by welding, followed by grinding and polishing.  The repaired runner was heat treated to relieve any heat stress from welding and then checked for its dynamic balance before it was sent back to the plant.
