The Champlain Water District utilized a variety of methods, including high-resolution inline leak and air pocket inspection, transient pressure monitoring (TPM), and a structural design check to ensure a critical transmission pipe’s design was sufficient for current operational conditions.

Champlain Water District (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. When evidence of corrosion-related breaks was revealed in nearby distribution mains, CWD became concerned that a critical metallic water main in their system could be next.
