The water utility in Madison, WI, is experiencing economic turmoil, a sign of the strain faced by many water utilities across the country.
Last week, over 100 U.S. water industry personnel convened in Laurel, MD, for a workshop to address strategies and trends in modernizing water and wastewater infrastructure. Xylem Inc. brought together representatives from a multitude of public and private municipal water utilities, engineering and consulting firms, and Xylem subsidiaries — Pure Technologies, Visenti, Sensus, and Emnet — to discuss challenges, solutions, and best practices for water infrastructure management.
This heated debate continues to rage on in boardrooms, online forums, and tradeshow floors around the world.
Execution of recommendations based on two evaluations for Volusia County, Florida has now saved the County more than $30 million since 2008. The County implemented many of the recommended improvements as described in the two evaluations for the Public Works Department that were conducted in 2007 and 2009. With a considerable investment of time and resources, the County desired to determine the impact and results of their efforts. In 2017, the Department management and County leadership initiated a proactive effort to evaluate the before/after results from these two previous evaluations over the past 10 years.
Reverse osmosis (RO) has become a widely utilized treatment process for diverse applications such as medical and laboratory research, desalination, and treatment of industrial wastewater and municipal water/wastewater. Because of its widespread use and technically advanced nature, a variety of quality parameters should be monitored by those treatment operators who utilize it.
Michigan is close to completing its work on what could be the nation’s strictest drinking water rules for lead.

Water resource recovery (WRR) plants must monitor ammonium and orthophosphate. Permitted levels for these nutrients in effluent discharge are becoming increasingly tight because state environmental agencies and the U.S. Environmental Protection Agency (EPA) are requiring dischargers to reduce the amount of nutrients in their effluent.
I was always fascinated with science as a kid, and as I have grown older that curiosity has not waned. In fact, it has increased exponentially. On family outings, it’s usually the case that I’m pulling my granddaughter aside to describe to her the intricacies of a water or wastewater plant seen from the road or pointing out the sewage lift stations that dot the highway. This is a particular favorite of mine; it’s the equivalent of license plate spotting for the environmentally inclined.
Nitrogen and phosphorus are two wastewater constituents that, together, pose one of the most high-profile threats for consumers and the environment. An abundance of these elements is what ultimately leads to the formation of toxic algae in surface waters, an environmental issue that regularly gains mainstream headlines and, in some cases, poses an acute health risk to consumers.
A new report gave water ratepayers a voice on whether their water utility is meeting their needs.
Falling into disrepair and neglect, the country’s water infrastructure is posing an enormous physical and financial challenge for many regions. However, many of these same regions are launching new plans and investments to accelerate infrastructure repairs, which are often going hand-in-hand with larger economic development activities, including the support of long-lasting career pathways.
Smaller Oklahoma city upgrades their wastewater treatment plant’s sludge handling system using the latest intelligent equipment. The new pumps went into service in April and May 2017 and the staff is thrilled that they have experienced no clogging.
As water distribution infrastructure ages, the potential for leaks grows and the need for condition-driven asset management increases proportionally. As with so many other aspects of water operations, planning ahead is key. Good system diagnosis using noninvasive procedures provides an accurate and cost-effective assessment of distribution system integrity, just as noninvasive monitoring of heartbeat, pulse, and blood pressure plays an important role in human health.
The new Ovivo MBR Knowledge Center and MICRODYN-NADIR Manufacturing Plant for BIO-CEL MBR Membrane Modules is a 27,000-square-foot facility that houses a fully automated, cutting edge membrane module production line, as well as offices for Ovivo designers, engineers, and technicians.
Global demand for power and water is accelerating — and the Middle East is no exception. A burgeoning population combined with multiple industrial diversification programs is fueling a boom in power and water projects. During the first three quarters of 2017, about US$30 billion of major power contracts and US$20 billion of water projects were awarded across the region. In 2018, the figure is looking more like $60 billion with the two sectors combined.
It’s a four-peat.

As if they don’t already face enough challenges, water treatment plants (WTPs) in the western U.S. have yet another potential problem lurking in their source water waiting to blossom when they least expect it. This specific problem comes in the form of two invasive species: quagga mussels and zebra mussels.
One of the things that strikes me when I read Water Online is the expansive range of industry imperatives — from contaminant removal and wastewater management to desalination, infrastructure improvement, and drought prevention. And while we can always point to limited resources as an obstacle, a focus on capital constraints almost always ensures that progress won’t be made. But there’s one resource that increases the likelihood of project success across the board in the water sector.
Consumers are taking advantage of technology to gain knowledge and demand rapid, inexpensive (sometimes free) delivery of goods. In supply chain terms, that’s called the last mile — getting the product to the consumer as quickly as possible.
Designing an underground stormwater storage system is a unique step in the overall construction process for each site. The size of the inlets and the conveyance pipes are determined by flow rate, elevation, and slope. This information is entered and calculated by stormwater management software to determine the drainage calculation. But many of the measures build upon one another or vary based on different criteria, so it can be a pretty complex process. That’s why we’re going to take a look at the top 10 factors that go into designing and installing one of these systems.
Philadelphia is placing a major bet on mussels for improving water quality in the Delaware River basin.
Desert life depends on reliable access to water. In Namibia’s stark Namib Desert, where I spent 18 months doing research for my Ph.D., wildlife concentrates around natural springs. Increasingly, animals there also rely on man-made ponds intended for livestock.
The Santa Barbara desalination plant located in the south-eastern part of Curaçao provides drinking water to about half of the population of this Caribbean island. With an average precipitation of approximately 500 mm, rainwater is the only natural source of freshwater in the island. Government efforts to address the water shortage problem date back to the 20s of the last century. Initially based on evaporation, the seawater desalination evolved into the reverse osmosis technology in the 90s. After several years of experimenting with RO, Aqualectra, the municipal supplier of potable water and electricity for Curaçao, took the decision to move forward with this technology and in 2003 started a project to build a SWRO desalination plant.
