The landscapes and environments in which we live are constantly changing, and ensuring that resilient infrastructure is in place to support local communities is a priority for all cities. In regions where natural disasters occur and pose significant threats, such as wildfires and earthquakes, and as seen most recently in areas such as Lahaina, Hawaii, and the Palisades in the Santa Monica Mountains of Los Angeles County, California, Ductile iron pipe (DI pipe) has proven to be a durable and reliable choice for water infrastructure. This article will discuss why selecting the proper material for underground infrastructure is crucial in combating natural disasters and enabling communities to respond more effectively with a reliable source of potable water and vital fire protection.
Utility pipelines provide for some of the most basic needs within our society. Essential services, such as supplying potable drinking water to our homes and businesses or sending wastewater away, are possible because of a network of buried pipelines. Whatever pipeline materials are used, they are expected to meet minimum service qualities such as withstanding leakage. This resiliency to leakage eliminates waste of our precious drinking water and prevents polluted soils from wastewater in the pipeline's proximity.
Within this article, we will discuss the depth of cover and the key factors to consider when selecting the type of trench (or laying condition) for your application. We’ll also discuss why it is important to choose the correct trench application, not only for today but also for future adjustments or improvements planned for the surrounding area where the pipeline is being installed.
Over the course of my 30+ year career with McWane Ductile, I’ve had the opportunity to be a part of some remarkably interesting and detailed water pipeline projects. Several of these projects have required a partnership between the community, awarding authority, contractor, water works distributor, and material manufacturer to ensure the projects were installed efficiently and correctly. However, few have matched the scale, complexity, and collaborative effort of the Saugus River crossing—part of the massive Belden Bly Bridge Replacement Project in Massachusetts. This project stands out not only for its technical challenges but also for the preparation, planning, and collaboration of key partners that brought it to a successful conclusion. In this #IronStrong Blog, you’ll hear the when, why, who, and how of this complex and intricate Ductile iron pipe (DI pipe) waterway crossing.
Sustainability and Resiliency are today's buzzwords, especially concerning water and wastewater systems, but what does this really mean to you, the designer, manager and/or operator? Utility people today are bombarded with the answer to this question, and we believe that there is no one answer because every system is unique and experiences different priorities and different challenges.
Gaskets Are Great
Rubber gaskets are the reliable workhorse of any Ductile iron pipe (DI pipe) joint. They provide long-lasting flexibility and a watertight seal against internal pressures upwards of 1,000 psi.
What they don’t do, however, is bind the joint longitudinally against such forces. In fact, without assistance from other variables, a push-on or mechanical joint of any diameter would calmly separate lengthwise against pressures as low as 50 psi.
Have you ever heard the saying, “To the man who only has a hammer in the tool kit, every problem looks like a nail?" (Abraham Maslow) In the water utility industry, some folks may feel this way when faced with a pipeline installation that must circumvent natural or human-made obstacles, especially water crossings. So if going around or above isn't an option, what's left? How about below?
In today’s modern world, there are more tools available for installing water pipelines, such as open trench/cut, above-grade pier systems, and Horizontal Directional Drilling (HDD). In this blog, we’ll discuss the benefits of using Ductile iron pipe (DI pipe) for HDD and provide some considerations and tips for your pipeline installation
The more than 75 years of ongoing research on iron pipe corrosion and the use of polyethylene encasement has led to this type of corrosion mediation becoming the accepted industry practice for protecting ductile iron pipe. So, the question many may ask is; “Since I had such success with standard polyethylene encasement, why should I now use V-Bio Polyethylene Encasement instead?” To best answer this, it’s imperative to look at what specifically V-Bio provides that is not available with standard polyethylene encasement.
Can McWane Ductile provide bonded coatings? A good question recently posed and more frequently asked due to a greater recognition of potential corrosive environments. To correctly address this question, some other questions need to be answered first.
When choosing an appropriate utility piping material for your water or wastewater project, there is so much more to consider than just the purchase price alone. This comparison between two popular piping materials – HDPE and Ductile iron pipe – demonstrates the need for more than just a cursory review or habitual choice. At McWane Ductile, we are always available to run through the matrix with you. Some installations or conditions do favor alternate materials, yet it’s hardly ever a cut-and-dried deal. Let’s take a closer look to find out why.
