This powerpoint presentation provides information on external corrosion control, the most critical component of effective water main infrastructure planning and management. Topics covered include: design and construction; operation and maintenance; and, rehabilitation and service life extension strategies. Project summary included: corrosion is inevitable (unless you do something about it); corrosion is predictable; corrosion is often the root cause of cast and ductile iron pipe failures; proven, cost effective corrosion control strategies exist for new and existing pipelines; corrosion detection and control can be cost effectively installed and monitored; suitably designed, corrosion control is construction and maintenance friendly; cathodic protection is a simple, low-maintenance electrical system; and, corrosion control is key for effective infrastructure management. Includes figures.
