Certified Professionals

Certified Professionals Program

A PE Alliance (PEA) program to develop knowledgeable industry insiders and ambassadors who will advance the HDPE market in the water and wastewater sector and clearly communicate the value of HDPE in their own voice.

Program Overview

The Certified Professional (CP) Program was developed by the Alliance for PE Pipe to enhance participants’ knowledge of HDPE and their ability to communicate it clearly to others both within the industry and to end users. The program builds on more than fifteen years of success and contributions from expert, volunteer instructors and industry leaders.

More than a training program, CP is an investment in the growth of the HDPE industry. By developing professionals who can confidently represent their companies, explain HDPE and advocate for the industry, the program expands the number of credible voices carrying the HDPE message into the marketplace. Each Certified Professional becomes an industry ambassador who can help educate customers, influence specifications and create new opportunities for HDPE.  The program is available to PEA members only.

Participants gain a broad understanding of the HDPE industry, including the people and companies that shape it, how pipe is manufactured and joined, key installation methods and the customers and markets that drive demand. They also learn directly from industry leaders, gaining practical insight into how HDPE projects move from specification and design through manufacturing, distribution, installation and long-term operation. Students are required to pass a test once each year.

In-Person Events

The program includes two in-person events each year that anchor the online coursework and bring the class together.

PE Showcase

Held the first week of December, Showcase is where the class gathers for the Certified Professionals kickoff, participates in sessions throughout the week and closes with a group meeting.
