Penstock productivity improved
The Strawberry Water Users Association recently realized a significant increase in output on their hydroelectric plant near Spanish Fork, Utah. The plant's output was declining steadily and the problem was determined to be caused by build-up in its 11,000 foot long, 18 inch diameter penstock. After considering replacing the penstock or using hydro-blasting, the association decided that the pipe could be cleaned internally with flexible foam pits. Following the cleaning operation, the plant's output increased 22 percent to 345 kW. The new output level represents an increase in the association's annual income from the sale of electricity of $32,850 -enough to cover the costs of the equipment and contractor costs in approximately one year. The association plans to maintain maximum production by pumping an 18 inch pig down the line each year.
