The distribution system of the Portland Water Bureau includes about 15,000 hydrants. The authors considered costs and benefits of hydrant repair and replacement actions. An analysis was focused on supporting and addressing certain policy decisions ¿¿¿ whether it was cost effective to expand the hydrant overhaul program and potentially reduce repairs and replacements; what is the failure rate of hydrants and, consequently, what is a sustainable level of replacement that needs to be funded; what would be the future rate of hydrant failure under various repair and replacement strategies; and, whether it is cost effective to expand salvage part efforts.
