Pipe Material Considerations in Infrastructure Design

• Overview

America's water and sewer systems are facing an infrastructure crisis. As much as 80% of the value of these systems is in pipe. Although many of these pipes have served admirably, some with as much as a century of service or more, the time has come to begin replacing these pipes. How then does the design and utility professional get the most out of their piping dollar? Although there are many choices in modern pipe materials, appropriate, conservative, design procedures need to be followed for each in order to achieve the value these materials offer. They then must be installed in accordance with recommended practice and guidelines. This OnDemand Webinar will assist the piping professional in making appropriate choices and decisions among the various piping materials.
