On the banks of Puget Sound and in the shadow of Mount Rainier exists Tacoma, Washington. The city is home to approximately 211,000 residents, making it the third largest in the state of Washington. Tacoma’s vision is one focused on stewardship and resiliency, as outlined the Environmental Services Department strategic plan: “We believe everything we do supports healthy neighborhoods and a thriving Puget Sound, leaving a better Tacoma for all.”
Solving water scarcity issues can be an expensive proposition. Desalination, for instance, is a notoriously energy-intensive process that requires significant investment in technology and equipment.
Proficiency Testing (PT) is the name used by the International Standards Organization for a procedure also known as “inter-laboratory study” or “external quality assessment” or “ring test”. Proficiency testing, in simple terms, comprises a sample sent to a group of laboratories for measurement. The labs know what might be in the sample, but they don’t know exactly what is there or the concentration. Their results are compared with the known or true value and the lab is assigned a “Z” score to show how closely their result came to the target.
Following a tragic accident in a Baltimore wastewater treatment facility, a local Department of Public Works (DPW) employee has been found dead.
Many utilities have done great work of moving customers to digital communications for their bills and payment confirmations. However, an important part of the billing cycle is often left to paper — the collections notices.
The North American Great Lakes contain about one-fifth of the world’s surface fresh water. In May, new high water level records were set on Lakes Erie and Superior, and there has been widespread flooding across Lake Ontario for the second time in three years. These events coincide with persistent precipitation and severe flooding across much of central North America.
Ever since the introduction of centralized water treatment and distribution systems, leaks have been the bane of their existence. Finding a way to make reliable repairs rapidly and without having to disrupt service goes a long way toward satisfying customer and utility concerns. Here are some strategies and tips for making the right choices easier, quicker, and less expensive, even in the midst of an emergency.
With aging infrastructure averaging more than 240,000 water main breaks per year across the U.S., viewing repair fittings as commodity products can backfire if the performance of those fittings cannot outlast the remaining life expectancy of the pipeline. Choosing repair fittings on price alone without regard for performance characteristics can lead to premature failure. Here are some tips to avoid such a calamity.
It’s every water distribution manager’s worst nightmare — the dreaded boil-water advisory. Even when faced with aging infrastructure, there are ways to alleviate timing and complexity concerns about emergency pipeline repairs in advance. Use this seven-step checklist to become better prepared to deal with water main break emergencies and to forestall the need to issue a boil-water advisory.
The good news about extending water service connections is that they represent new revenue opportunities. The bad news is that they can be costly and disruptive in terms of having to shut down the system and open it up. Before planning new service connections or extensions, compare how the following characteristics of hot-tapping with fabricated tapping sleeves can save both time and money in the long run.
The climate in Southgate, Ontario, is considered cold and temperate with significant rainfall throughout the year. Temperatures in winter average around -10°C and can drop as low as -30°C to -40°C for brief periods of time, which can wreak havoc on the local water storage tanks and distribution piping. Read more to learn how the installation of PAX Mixers has kept the tanks free from ice and has shown an improvement in disinfectant residual levels.
Debate about regulating per- and polyfluoroalkyl substances is heating up across the country as the extent of known contamination continues to grow at an alarming rate. Also known as PFAS, this large group of toxic fluorinated compounds was used widely in industrial and consumer applications. Progressive water utilities are trying to quickly get a handle on the problem to better protect their customers from even further exposure.

Houston has had more than its fair share of water issues in recent history, most notably a water quality crisis following Hurricane Harvey in 2017. Now, the city is making progress on a gargantuan drinking water treatment plant (WTP) expansion to change that narrative — at least on the drinking water side.
Fifty-one billion gallons. That’s the average amount of water flowing into Chesapeake Bay on a daily basis. And as all that water seeps, flows, and cascades across the watershed before it spills out into the Bay — the nation’s largest estuary — it picks up signature characteristics of where it has been.
More than 12,000 people are expected to attend the international ACE19 meeting, focusing on ‘Innovating the Future of Water.’
In a sign of just how critical the digital grid has become, the City of Baltimore is currently being held hostage by cybercriminals following a data breach.

Slurries of mud increasingly threaten the water we drink. This rush of sediment, known as “debris flow”, is a type of erosion where mud and boulders in steep catchments suddenly tumble down the stream channel, often traveling at speeds of several meters per second. And they don’t just damage water supplies — they can cut roads, damage infrastructure, and even kill people.
A long-term health crisis may be on the horizon if municipalities don’t slow the flow of antibiotics from wastewater to the environment.
Recent scientific research advancements at the microscopic level could help shape the future of wastewater treatment and reuse, which is critical to maintaining global health.
When drinking water leaves a treatment plant through giant pipes, with the help of huge pumps, the pressure can exceed 200 psi. The high pressure is a necessity because water must travel a long distance in some cases. Water towers scattered throughout the distribution system aid in the process so it can reach all utility customers. The problem is that not all distribution points in a water system are created equal.
When speaking with anyone who works for a water utility their priorities quickly become apparent. Water quality and reliability, intractably related to each other, form the core mission of any water utility. Without maintaining water quality and safety, customers may become sick or worse.
