How does one observe World Water Day? The occasion certainly sounds important, but ask your typical treatment plant operator if he or she knows the World Water Day date (March 22nd), or even that it exists, and a shrug of the shoulders might be a common response. Perhaps the busy job of providing us the precious resource prohibits them from celebration — so let's celebrate them instead.
Rangely is a remote town with a population of just over 2,200 people located in the upper northwest area of Colorado, thirteen miles from the Utah border. During the course of their routine maintenance, operators noticed problems with a distribution pump. Read the full project profile to learn how Process Solutions’ trained service technicians were able to walk them through a series of diagnostics to further isolate the problem and get the system was back up and running in a short period of time.
Wastewater treatment plants use numerous pumps in a variety of types and sizes to move water through the process. Depending on plant configuration, they may pump influent, activated sludge, thickened or digested sludge, biosolids, scum, filtrate, effluent, or reuse water. Each matrix has specific characteristics that engineers consider when designing pumping systems.
It’s the call no water treatment plant superintendent wants to receive, especially not while on vacation. Andy McClure, Superintendent of Toledo, Ohio’s Collins Park Water Treatment Plant, answered his phone to hear his head of operations report that the level of microcystin in the finished water was high, caused by a large harmful algal bloom (HAB) that was impacting the plant’s Lake Erie intake.
Drinking bottled water may mean guzzling down tiny bits of plastic.
Dangers to the water supply are not just bad for water utilities. They also pose a risk to another vital resource: beer.
Modern-era communication networks and data storage capacities are rapidly transforming the relationship between water utilities and their customers. The technology and infrastructure that we have today can provide timely water usage data directly to customers’ cell phones, creating the most transparent relationship that we have ever seen between water provider and consumer.
Driven by tight budgets and competing needs for limited CAPEX funds, wastewater treatment plants are increasingly looking to reduce their operating expenses. Many are now referring to themselves as water resource recovery facilities (WRRFs), reflecting a heightened focus on recovering nutrients, methane, and a host of other properties from their waste flows. The largest boon to date has come from thermal energy, but producing biogas comes with its own set of challenges, including accurate gas flow measurement.
Mounting data suggests that pollution from coal-burning power plants may pose a threat to drinking water.

“When the well’s dry,” Benjamin Franklin once said, “we know the worth of water.” Today, our freshwater supplies face serious threats — including drought, wildfire, and other impacts of a warming climate. From California to Cape Town, the worth of water has become crystal clear.
Activated sludge systems have been a cornerstone of wastewater treatment for over 100 years. This biological process uses suspended growth microorganisms to break down and consume organics and remove nutrients from the wastewater. The heart of the process takes place in aeration basins, where the microorganisms need to receive sufficient oxygen to stay alive.
Utility and government agencies with limited resources for water infrastructure projects aren’t limited to traditional approaches; collaborative approaches such as progressive design-build delivery give owners more flexibility to optimize not only the price, but also the overall result and experience.
There are many positive changes on the horizon for the water and wastewater industry — new ideas and technologies that should enable more efficient and reliable operations, better water quality, and cost savings — but the forecast for the future is not all sunshine. There are some storm clouds brewing, literally, and water system managers need to prepare for the impact of severe rains.
Ever since Coriolis flow measurement technology achieved mainstream appeal, industry has been fervently striving to take advantage of its benefits. And while Coriolis is clearly a highly advantageous solution for many crucial flow measurement applications, it is not without flaw.
With so much demand on operating budgets, water and wastewater utility dollars must be spent — or conserved — wisely. Energy expenditure is a prime savings opportunity, but how do you pull it off successfully? Here are some factors, illuminated with a case study, to consider.

Depletion of water supplies for potable and irrigation use has been a major problem in the world. Seawater desalination by reverse osmosis has become a common solution to address these demands. Using alternative sources of water requires implementation of increasingly stringent standards of water quality obtained by reverse osmosis processes, and boron is one of the most challenging contaminants in the final product.
Until recently, multi-stage centrifugal blowers and gear-driven single-stage turbo blowers have dominated larger wastewater treatment plant (WWTP) operations. Turbo blowers in the 50 hp to 300 hp range have historically been popular for their low total lifecycle cost in mid-range WWTP applications (from 1 MGD to 20 MGD).
The digital revolution has reached our utilities, but not everyone is taking advantage of how it can, for example, make water and wastewater cleaner, healthier, and more efficient. National news media seemingly report daily on U.S. infrastructure, but they rarely get down in the trenches with the public works professionals who are accomplishing so much. Three of them, who are using the Internet of Things (IoT) to better manage critical assets, tell their stories here.
When it comes to the challenge of running high-speed turbo blowers at 40,000 rpm in the unforgiving environment of a wastewater treatment plant (WWTP), robust design goes a long way toward accommodating extreme physical demands with minimal maintenance and overhead costs.
A massive main break crippled water delivery in Atlanta last week, leaving many residents without water and thrusting more than 700,000 people under a boil-water advisory.
The third video of the series, follows how water is treated throughout the treatment process. Reviewing primary clarification of insoluble BOD and other settleable material, biological treatment, secondary clarification, tertiary filtration, phosphorus removal, denitrification, disinfection and discharge.
Many water utilities stay in close contact with ratepayers, but when budgets are tight, communications outreach is a task that sometimes gets pushed aside.
The cabins and store at the Wirib Tourism Park in the Northern Territory of Australia were served by an aerated wastewater treatment system (AWTS) that was aging, too small for peak flows, and unable to handle the park’s high-strength sewage. This resulted in untreated wastewater being dispersed not far from a local creek, creating health and environmental risks. The territorial EPA issued a notice to park custodians to address the failing AWTS or risk having the park closed.
Union Cements Company (UCC, Ras Al Khaimah), founded in 1972, is one of the biggest cement manufacturers in the UAE for Portland cement with capacity of 10,000 tons per day.
Since high-speed blowers were initially introduced in the U.S. about 15 years ago, they have been helping wastewater treatment plant (WWTP) operators reduce energy costs — representing up to 60 percent of all plant operating costs — without compromising plant performance. That is not to say, however, that adopting the new technology did not come without a steep learning curve. Here are several guidelines to help WWTP operators maximize the payback on an investment in high-speed turbo blowers.
Without an appropriate control strategy, even the best wastewater treatment plant (WWTP) equipment can struggle to deliver maximum efficiency. Because energy costs represent up to 60 percent of WWTP plant operating expense, air distribution designs and changing loading (biochemical/biological oxygen demand [BOD]/chemical oxygen demand [COD], ammonia) demands require control strategies designed to adapt to all eventualities efficiently. The following checklists, plus important Do’s and Don’ts, can help in identifying an underperforming control strategy and developing a better one.

About 300 convened at the two-day event, eager and ready to work together.
From Cape Town to Puerto Rico to Flint, Michigan, it's no surprise that drought, flooding and water pollution can devastate communities, impacting lives and hindering economic growth. But the physical components of water supply – its abundance or scarcity, levels of pollution, and the competition over it — are only half of the equation when it comes to overall water security. What's just as important is how water is managed by public institutions, such as water utilities and local governments.
The water and wastewater sectors are mostly regulated by their own organizations because they are exempt from federal OSHA regulations. But utilities are responsible for more than delivering water and wastewater treatment services. They must provide a workplace that is free from known hazards.
