Utility considerations in developing a galvanized iron water pipe management plan

Abstract Galvanized iron pipe (GIP) was once widely installed in publicly and privately owned potable water systems. This antiquated plumbing material can cause discoloration from release, head loss resulting corrosion scale buildup, occasional problems with lead (Pb) release to drinking water. In this work, a GIP management framework for utilities is formulated via literature review several case studies. The plan intended guide systems understanding addressing issues while considering consumer expectations, control challenges, variable performance, associated cost–benefit analysis corrective actions.
