Case Study
CHAMPLAIN WATER DISTRICT – VERMONT, USA
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.
THE CHALLENGE
After conducting their own risk prioritization plan, Joe Duncan, Chief Engineer for CWD, and his team kept with the proactive mindset and began a transmission main asset management program.
While the transmission system is relatively “young” and had no real break history, visual feedback from crews showed distribution mains in the vicinity of the transmission mains were experiencing corrosion-related breaks and in some instances looking like “Swiss cheese”. Due to the high importance of the transmission pipeline, CWD wanted to understand its condition and forestall potential corrosion issues.
