    Replacement Options for Penstocks

    Many wood stave penstocks installed in the last century are approaching the end of their safe, reliable, and useful service life. Once leakage surpasses the ability of typical maintenance to manage it, exterior deterioration of the wood staves, steel bands, and saddle foundations can accelerate. As deterioration progresses, continued maintenance may not be economically justifiable, and owners must choose either to replace or abandon a penstock. The most common replacement materials are steel, fiberglass-reinforced polymer (FRP), or concrete. The advantages and disadvantages of these three materials are presented through three recent penstock replacement projects where site conditions, station characteristics, penstock diameter, length, hydraulics, construction access, material shipping constraints, and cost all affected the choice of replacement material.
