As of October 2020, more than 47,000 wildfires have occurred across 36 U.S. states. Drought is a major factor, as a large portion of the West is currently experiencing the most severe level of drought, dubbed “exceptional drought” by the U.S. Drought Monitor. Humans cause the majority of wildfires with negligence such as unattended campfires, discarded cigarettes or arson, followed by natural causes such as unusually long-lasting hot lightning bolts.

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.
Polyethylene Encasement (Polywrap) was first used in 1958 and has successfully protected millions of feet of both cast and Ductile iron pipe (DI pipe). It has been the most popular method of corrosion control for DI pipe throughout the years. Today, it is the most widely used method of protecting DI pipe in corrosive environments.
Today, most water systems serve the public in two ways: by providing potable drinking water and enabling fire protection for the community. Fire protection provides more than just the obvious public safety benefits. It also enhances community property values and provides residents with lower home and property insurance rates.
November 8 is National STEM/STEAM Day, highlighting the importance of Science, Technology, Engineering, Arts, and Mathematics in children’s education. The manufacturing of Ductile iron pipe (DI pipe) and constructing pipelines for water and wastewater infrastructure are complex processes that rely heavily on STEM principles. In this #IronStrong Blog, we will explore the intricate connections between these fields and their significance in ensuring safe and efficient water and wastewater management now and in the future.
My local water utility recently contacted our home to inform us they were turning the water off from noon to 6:00 p.m. to repair a newly discovered water leak. This situation made me think about water loss, specifically how long the water line had been leaking, how many gallons of treated water was lost, and how a utility keeps up with water loss. This Iron Strong Blog describes the various components of a Water Loss Control Plan (WLCP) and the importance Ductile iron pipe (DI pipe) plays in an overall water management strategy.
Prestressed Concrete Cylinder Pipe (PCCP) has been used in water and wastewater applications for nearly 80 years. The thought process behind PCCP was sound, in that it would combine concrete's high compressive strength with steel's high tensile strength. However, like many products, PCCP has continued to fall short in the following years in many comparative categories to Ductile iron.
Have you ever considered how high temperatures impact your choice of piping material for a water system? It might not be something that comes to mind immediately, but it’s an important factor. Water treatment specialists pay close attention to water temperatures because they influence how the water reacts to treatment chemicals. Additionally, water and ground temperatures can significantly affect the performance of certain piping materials, particularly polyvinyl chloride (PVC).
Shallow aquifers prone to contamination, compliance with federal drinking water standards, and insufficient resources to replace aging infrastructure. These are some of the water issues that launched the creation of the Lewis & Clark Regional Water System and the construction of the Iowa Treated Water Pipeline – Segment 3.
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.
