The architects of Denver’s water infrastructure had a knack for predicting the future. They planned for the population of the city to grow.
Last week, thousands of water professionals met for the industry’s annual flagship conference. This is an important event at an important time as we give attention to our nation’s infrastructure. While roads and bridges are visible reminders of the importance of infrastructure, equally important components are out of sight, but they need to always be in our mind. These critical components are underground pipelines that provide water and wastewater service.
On July 26, 2013 Gainesville Regional Utilities discovered a pipeline failure at a butt-fused welded joint on a 36” HDPE Sewer Force Main. It was determined that the joint failed due to a combination of several incorrect construction methods used during the installation of the pipeline. Once discovered, GRU installed JCM 102-3600 x 18” wide Multi Band Universal Clamp Couplings (4-band clamp) to temporarily seal the leak while a permanent repair was considered.

The New Rochelle Wastewater Treatment Plant is located in the Westchester County, New York, discharging to the Long Island Sound. It serves a population base of 65,000 people and is permitted to treat average flows of up to 20.6 MGD. Operating with primary clarification and pure oxygen-based activated sludge treatment since a 1979 upgrade, the plant only removed BOD and TSS from the wastewater.
Water, classified as one of the basic elements since ancient time, is so essential, so simple, yet can be so challenging to deliver at high quality in high volumes. Pursuing the “perfect” glass of water involves two major influences: 1) regulatory requirements and 2) aesthetics or organoleptic quality (i.e., taste, odor, appearance, etc.). To start, it helps to be blessed with the good fortune of good source water quality, but beyond that it comes down to how a water utility treats and “polishes” the final product. Even for utilities not totally obsessed with garnering national taste-test honors, here are several factors to be considered when searching for the perfect glass of water, and the role that turbidity measurement can play in them.
Turbidity, a measure of the cloudiness or haziness of a fluid, was originally intended as a qualitative measure of the aesthetics of drinking water. It is not a measure of actual particles in the water; it measures how much those particles affect light being transmitted through the water, or how that light reflects off particles in the water. Today’s turbidity designs and methods have been regimented in an attempt to bring quantitative consistency to the measurement for both aesthetic and pathogenic qualities of drinking water.
Conserving energy and saving costs are always on the minds of wastewater professionals. Aeration accounts for more than 50 percent of electrical usage at most treatment plants. Improved aeration efficiency will always work toward the goals of saving energy and reducing operating costs.
Ratepayers are debating the merits of a proposal for a new desalination plant in Orange County, CA.
Turbidity, as a measure of cloudiness or haze in water, has many useful applications for industrial processes, pharmaceutical manufacturing, environmental monitoring, and utility applications. Unlike general commercial applications, however, the use of turbidity readings in municipal drinking water treatment comes with unique demands and considerations related to regulatory compliance.
As industries expand, they typically need to increase the capacity of their wastewater treatment facilities. Increasingly stringent regulatory requirements, such as lower nitrogen limits, may also signal the need to boost treatment capacity. Installing additional tanks and larger equipment not only adds capital costs but increases operating costs as well.
September of 2017 was the busiest month of hurricane activity on record, according to the Weather Channel.
Turbidity measurement is both a nebulous, oft-misunderstood concept and the master link in a chain of events affecting U.S. EPA drinking water compliance. It can influence, or be influenced by, almost every other link in a water treatment process. Here is a quick overview of turbidity’s relationship to drinking water compliance standards and some tips for keeping a water treatment process in balance.
Access to clean, safe, fresh water is one of the greatest challenges facing humanity in the 21st century. By some estimates over 1.5 billion people face water scarcity issues that directly threaten their health or economic welfare on a daily basis. More concerning, the impacts of climate change and global population growth are expected to exacerbate these issues to impact over 2.3 billion people by the year 2050. These sobering facts are why six of the United Nations (UN) Sustainable Development Goals (SDGs) are focused on providing access to clean, safe water. Part of solving this challenge is reducing industrial water consumption to conserve water resources.
Health regulators in Oregon are creating new regulations to protect drinking water from cyanotoxins.
I was having lunch with a former colleague a few months ago and the subject of produced water recycling came up. During the course of the conversation, he asked me: “Isn't this just a reverse Ponzi scheme with produced water? Ultimately, if they stop fracking, they [the operators] are going to have to deal with a lot of dirty water they don't need!”

Every water distribution utility has a strategy for infrastructure asset management and repair — from simply reacting to breaks, to scheduling main replacements based on system-specific history, to prioritizing infrastructure repairs based on mathematical calculations of risks and consequences.
It’s increasingly obvious to me that the gap in the general understanding of technology is continuously increasing with those that are not working in the space every day. I am referring to industrial technology versus the general consumer technology market.
Fine-tuning for best performance at water treatment plants (WTPs) and wastewater treatment plants (WWTPs) requires versatile and accurate instrumentation to monitor and respond to changing conditions. Getting the most out of those meters, gauges, and analyzers requires knowledgeable operators. That is why instrumentation decisions should be made not only on feature-rich technologies and quality performance, but also on the documented support and training that will enable staff to maximize the value of the investment.
A utility worker died while working under a manhole in Florida on Friday.
Economist Harold Pollack's New York Times article suggesting priorities for your philanthropic work was a fun read for those of us who would love to imagine what we would do with $131 billion. Unlike Pollack, I'm not going to tell you how to give away your money — you earned it, it's yours, and you can do what you want with it.
From the largest metropolitan water treatment plant (WTP) or wastewater treatment plant (WWTP) operations to the smallest rural systems, the goals are essentially the same — achieve regulatory compliance and the most efficient results at the lowest practical cost. The most feasible (i.e., affordable) control solutions vary by process, plant size, and budgetary limitations. Here are several high-level guidelines to achieving a common strategy that works across virtually all applications: good data, properly analyzed, yields good results.
In small Appalachian towns, finding enough money to maintain wastewater infrastructure is a big challenge.
Many water treatment plant upgrades and purchasing decisions are entirely determined by price. However, long term costs such as energy and maintenance, are often not considered in the initial stages. This potentially leaves water treatment plants with ongoing and reoccurring expenses, which could result in higher energy bills, increased purchases of spare parts, and operator labor time.
For years, centralized water and wastewater treatment facilities have been the norm. Large treatment plants typically provided the most cost-effective solution, due to economies of scale. However, new technology is tipping the scales, as decentralized treatment solutions are providing improved treatment at reduced costs.
In an industry faced with around-the-clock operations and penalties for noncompliance with regulatory standards, it can be easy to lose track of periodic maintenance requirements whose impacts might not be noticeable until it’s too late. Ignoring the influence that measurement and analytic equipment maintenance can have on water treatment plants (WTPs) or wastewater treatment plants (WWTPs) can be costly. Fortunately, equipment suppliers who bundle after-sale services tailored to WTP and WWTP needs offer new opportunities for instrumentation users to stay ahead of the curve in terms of timely response to changing performance.

Most treatment systems for removing iron and manganese from groundwater sources use chlorine, oxygen or various other chemicals to oxidize the clear state of iron and manganese to an oxidized or solid form so the particles can then be filtered out. If complete oxidation occurs and if the oxidized floc is of suitable condition, a filtration system consisting of filter sand and anthracite is used.
