When evidence of corrosion-related breaks was revealed in nearby distribution mains, Champlain Water District (CWD) became concerned that a critical metallic water main in their system could be next. To avoid any potential breaks, and the economic, social and environmental costs associated with a failure, CWD jumped into action. By taking a proactive approach to understand the true condition on a section of this high-value ductile iron (DIP) transmission main, CWD avoided unnecessary replacement work and was able to direct funds where they are truly needed.
CWD is an award-winning regional municipal organization that supplies drinking water to 12 municipal water systems in Vermont. As the largest water supplier in the state, CWD serves approximately 75,000 residential, commercial and industrial users. CWD draws water from Lake Champlain, and three high value water transmission mains supply water to the user municipalities. The year 1972 saw the completion of multiple transmission main projects to link all members of the newly created Champlain Water District, which has 54 miles of transmission mains constructed of ductile iron, with the majority running at 24 inches.
Although CWD is a relatively small consolidated water district, they are a leader in their state, nationally recognized for water quality and asset management. As a wholesale water supplier, CWD demands continuity of supply, with no disruptive surprises to service.
