In recent years, an increasing number of locales and authorities have adopted greater controls of the water used in hydrostatic testing, flushing, and disinfection of utility pipelines, post-installation. Whether from a feeder hydrant to be metered, or when there might be a fee applied on the volume of water used, how does an engineer, contractor, or inspector compute the amount of water needed for these tasks? Sometimes it is required to demonstrate during flushing operations that the water inside a pipeline section has been “exchanged” a designated number of times during the specified flushing. So, just how much water does it take to fill or flush 1,500 feet of 12-inch class 52 DI pipe?
During the decades in which I have managed large and small water utilities throughout the country, I have experienced several challenging scenarios. Whether it was a major oil spill in the river that provided our raw water supply, a winter with sub-zero temperatures and no snow cover where small water mains were frozen solid in the ground, or the total transitioning from a groundwater source to a surface water source with all the different treatment methodology involved, I had never considered the terminology “the new normal.”
Celebrating Earth Day reminds us of the glorious surroundings we are provided with, bringing joy and happiness to our everyday lives. A variety of topographies span from rivers and streams to mountains and valleys. Even deserts and dry climate regions provide some of the most picturesque landscapes known to man. Earth Day is conveniently celebrated in the spring when flowers and trees burst with bountiful flowers and blooms. New life abounds as animals give birth to a new generation. A simple family picnic on a manicured lawn or trip down a mountain on a bike are just a couple of examples of pleasures we can enjoy.
This article takes a deeper dive into concepts outlined in the July 2020 entry prepared by my co-worker Gary Gula, How Much Does Ductile Iron Pipe Weigh and Why Does It Matter to You? Specifically, we will focus on the pipe weight itself, answering questions such as: From where do these weights originate? Why do we show weights on each pipe? How trustworthy are these weights as provided? And, What do these weights mean to me, the pipe customer?
Help Me Ditch Doctor,
The inspector on this pipeline project came out here and just told us we are laying pipe in the wrong direction. He said the bells have to face the other direction like the plans show. He wants us to dig up the 1,000 feet of pipe we've already installed and reverse each pipe. Is he for real? Does it really matter?

Calcium hypochlorite is an inorganic compound added in granular or tablet form added to water to kill germs that can make people sick. When used correctly, this compound destroys germs that can cause numerous health problems. ANSI/AWWA standard C651-14 incorporates essential procedures and requirements for the disinfection of new potable water mains. In this blog, we’ll cover why, when, and how it’s used in the waterworks industry.
As a companion piece to the Iron Strong Blog entry, What Type of Ductile Iron Pipe Joint Is Right for You? by Scott Rhorick, this article takes a deeper dive into the specifics of installing restrained joint Ductile iron pipe (DI pipe) through a steel casing pipe. While many options are available industry-wide, this article concentrates on using TR Flex® or Sure Stop Gaskets in cased installations.
There are a variety of Ductile iron pipe (DI pipe) joints on the market. These different types of joint designs can now allow for additional benefits for various applications. Joining pipe together is just as important as the pipe itself. It sounds like a simple procedure, but the environment in which the pipe is assembled is critical.
Thermite welding, often referred to as CAD welding, on Ductile iron pipe (DI pipe) and products is a common practice in our industry today. This welding technique of using heat from an exothermic reaction to produce coalescence between two metals is most often used to bond the Ductile iron joints for cathodic protection or for the opportunity to add a cathodic protection system at a later date. In this Iron Strong Blog, we will discuss when, why, and how to properly CAD weld on DI pipe.
