Impactful site for the impact of aging infrastructure in the US. Corrosion, leaks and breaks in old-technology pipe materials are degrading our water delivery and sewage treatment systems, which are critical to public health and the environment. Every day, 850 water main breaks occur in North America at a total annual repair cost of over $3 billion. This doesn't include the high costs of emergency equipment, depleted water supply, traffic disruptions, and lost work time. Experts note that corrosion is the leading cause of this water main break epidemic.
