Safe Drinking Water - How Do We Ensure The Highest Standards?
01/03/2020 In Our Company Products TechnicalSafe drinking water is essential for sustainable human life. Do you lie awake at night wondering if the water you are drinking is safe? Do you dream about the type of water lines used to transport water to your home or business?
If you are a design engineer or an official responsible for providing clean, safe water to hundreds, thousands, or even millions of residents, then you are most likely the type of person who dedicates a major portion of your time thinking about water quality.
Thankfully, there are entities and standards in place to ensure that products used in water transportation systems are of the utmost quality. In this blog, we’ll discuss the who, what, why, and how products designed to transport safe drinking water are monitored and tested during the manufacturing process at McWane Ductile to meet quality standards.

What is a Water Loss Control Plan & What Importance Does Ductile Iron Pipe Play?
06/30/2023 In Products TechnicalMy 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.

Should A Water Utility Manager Let System Infrastructure Dictate Water Treatment Methodology?
05/22/2020 In Environmental & SafetyProviding safe, clean water to customers of a water utility is unquestionably JOB ONE. Meeting this goal has always been a formidable challenge in many ways. Source water quality can change dramatically due to weather factors and other phenomena. Additionally, increasing drinking water standards throughout the years evidencing higher detection technology and more sophisticated medical research regarding the health effects of contaminants has required water systems in some cases to change treatment methodologies dramatically.
Should the pipeline material placed in a drinking water system in any way limit decisions of today or in the future regarding the water treatment methodology chosen to best provide safe, clean water to customers? I THINK NOT!

Two Key Components of Water Systems Directly Related to Pipeline Material Selection
07/29/2022 In Products TechnicalThere are many "moving parts," as water professionals know, in the operation of a water system. The intricacies of not only supplying customers with a safe water supply but assuring that supply is adequate, including paramount necessities such as fire protection, many times create an ever-changing balance of key parameters within the water system. When the system operator affects such changes, there should be no concern by the operator regarding the transmission and distribution system to accommodate these changes. This article will highlight two system components that can be directly affected by material selected for system underground infrastructure.

Cyclic Pressures - What's the Difference Between Ductile Iron & PVC and How Do I Accommodate In Pipe Design?
07/25/2020 In Products TechnicalThis entry in the Iron Strong Blog compares the performance of Ductile iron pipe (DI pipe) to Polyvinyl Chloride (PVC) pipe against cyclic pressure variations in piping systems. Cyclic loading, or more accurately, cyclic surges, is a phenomenon where pressures in a pipeline frequently vary due to changes in demand, operating conditions, storage tank levels, treatment plants, and pump starts and shutdowns. Surges can also occur during common field operations such as exercising or flushing fire hydrants or valves within the system, which can drastically change flow parameters, causing surges or water hammers.
