Protecting critical water infrastructure from corrosion

Unchecked corrosion can rapidly compromise critical infrastructure. According to the National Association of Corrosion Engineers‘ Impact Study, the annual cost of corrosion as of 2013 was $451.3 billion for the U.S. alone. Essential services, which includes the water industry, accounts for $146 billion of annual corrosion costs.

Carollo’s Corrosion Group is responding to this pervasive challenge by implementing strategies that protect and preserve clients’ assets. Whether during design, construction, or ongoing maintenance, our team has the expertise to identify and mitigate our clients’ corrosion risks and enhance the long-term viability of their investments.

The essential role of materials selection in preventing corrosion

An effective corrosion strategy requires a thorough evaluation of material options, particularly in aggressive environments. Our Corrosion Group’s experience spans corrosion-resistant alloys and non-metallic alternatives, as well as failure analysis and rehabilitation methods.

Coatings are the first line of defense from corrosion

Customized protective coatings are essential to withstand the environmental challenges faced by metallic, composite, and concrete structures. Our services include the selection, specification, and inspection of coatings for immersion, burial, atmospheric, and other challenging conditions.

Using electrochemical techniques to protect buried or immersed structures

Cathodic protection (CP) is an electrochemical method to protect underground and submerged structures from corrosion. We design, test, and implement CP systems that safeguard storage tanks, pipelines, concrete structures, immersed gates, and other underground wastewater and water treatment facility components in diverse environments.

Water infrastructure: field testing and inspection

Effective corrosion and CP mitigation requires systems to be maintained and regularly checked. Carollo’s corrosion and construction management teams work together to provide coatings inspection and CP testing to save our clients time and money by preventing corrosion failures before they occur.
