Jerry, Sept 24, 2022; I'm sitting on the beach near the northern tip of Captiva Island, Florida. I’m on vacation with my wife, enjoying the warm sun, dolphins playing, and birds feeding as if there was no care in the world. Admittedly, most people in the area were already aware of the tropical storm developing in the Caribbean Sea and wondered, will the storm become a hurricane?
In regions prone to seismic activity, the resilience of critical infrastructure plays a pivotal role in public safety. Among essential systems, water distribution networks are particularly vulnerable during catastrophic earthquakes, where ground movement and soil liquefaction can cause widespread pipe failure. Ductile iron pipe (DI pipe), however, has emerged as a highly reliable material due to its superior properties, joint flexibility, and proven performance in past seismic events. This #IronStrong Blog examines how the unique design and strength characteristics of DI pipes contribute to their remarkable ability to withstand the intense stresses of major earthquakes, ensuring continuity of service when it is needed most.
Selecting the right pipe material is essential for the longevity and success of any water infrastructure project. While Ductile iron pipe (DI pipe) and High-Density Polyethylene (HDPE) each offer distinct benefits, their differences in strength, performance, and long-term cost are significant. This article serves as a refresh of our previously published article in November 2019. It outlines key comparisons to help engineers and specifiers make informed decisions based on project-specific conditions, such as soil type, pressure, and environmental factors.
It’s National Engineers Week (EWeek). Founded by the National Society of Professional Engineers in 1951, EWeek is dedicated to promoting careers in engineering and technology and to developing a diverse, well-educated future engineering workforce. This #IronStrong Blog post highlights the importance of engineers and their impact on the waterworks industry.
In our often-frantic daily routines, we rarely stop to think about something as simple as the water we consume daily. How does water get to our home? How do we know the water is clean and safe? Who’s responsible for providing this critical need? With May 3rd through the 9th, 2026, being Drinking Water Week, this #IronStrong Blog highlights the importance of water workers and sends a much-deserved thank you!
Cast iron pipe was introduced to the United States in 1816. Since then, numerous other piping materials have been offered and utilized. None were able to supplant cast iron as the leading performer until Ductile iron pipe became available. The introduction of Ductile iron pipe (DI pipe) to the marketplace in 1955 remains among the most significant advancements in the history of the pressure pipe industry. It was quickly recognized as a pipe material with all the established durability of gray cast iron, yet with added strength and resiliency from its innate and lasting flexibility. It was first used for special and severe conditions of high pressure, such as where water hammer and excessive external loads might have existed.
Over the last few years, the world has been affected by many things, and the ongoing repercussions are still seen today. These effects also impacted the waterworks industry and the handling of pipe stock and pipe yards. During that time, we witnessed delays in the supply chain and extended lead times. Manufacturers and distributors were keen on getting pipe in their yards and holding more quantities and sizes than ever. Pipe and gaskets then began to sit for longer periods. Due to the durable nature of Ductile iron pipe (DI pipe), sitting idle did not affect the product, but the lack of use for pipe gaskets was more apparent.
The water industry in the United States has experienced many challenges throughout the years. The good news is that these challenges have been met head-on by experienced, dedicated professionals who continue to provide their customers with clean, safe drinking water even though the bar of excellence continues to rise. One measure depicting the priority of these challenges is the State of the Water Industry Survey, conducted annually by the American Water Works Association. “AWWA’s State of the Water Industry (SOTWI) Survey is designed to identify water sector challenges and investigate possible underlying causes and drivers. In November 2022, when the survey closed, 4,123 water professionals had shared their opinions by responding to the survey—our highest number of responses yet!”(1)
The choice of materials in water infrastructure is crucial in ensuring the system's durability and reliability and influencing operational costs. Water and wastewater treatment plants are typically the largest energy consumers for municipalities, accounting for 30 to 40% of total energy consumption. To protect their systems from overload, energy companies must implement rolling blackouts during extreme weather. This #IronStrong Blog discusses the benefits of using Ductile iron pipe (DI pipe) in your utility water system and how its key advantages can save you money compared to other materials.
We in the United States are most fortunate, for the most part, to have access to safe, clean drinking water. Even when traveling, we are not hesitant to draw water from a hotel faucet to brush our teeth or even fill a glass to drink. This privilege is no accident.
