DIPRA's Commitment

From its inception more than 100 years ago, the Ductile Iron Pipe Research Association (DIPRA) has provided accurate, reliable, and essential engineering information about cast iron—and now Ductile Iron—pipe to a wide variety of utilities and consulting engineers.

DIPRA'S Commitment

Because Ductile iron pipe is the best answer to America’s water infrastructure needs, DIPRA’s mission is to help citizens, decision-makers and professional engineers understand and appreciate the many advantages that Ductile iron pipe offers to water and wastewater utilities and their customers. We invite consulting and utility engineers to take advantage of our many services, including our in-field regional engineers and technical staff.
