2018 is sure to be marked with advancements that make water and wastewater treatment more efficient and sustainable. To keep up with the areas best poised for improvement this year, here is a look at three practices that are in need of change.
Water professionals are constantly looking for ways to produce the highest quality water while staying within limited budgets. In addition, regulations are constantly changing, becoming increasingly stringent. New technologies are essential to meeting customer demands for quality and cost.
The water system in Missoula, MT, had been private for over a century. In June, the city regained ownership of the system and over six months later, it’s interesting to see where the transition stands.
With some federal help, researchers at Iowa State University (ISU) and Ohio State University (OSU) are looking to build up defenses against toxic algae growth in source waters.
Officials in the state of Michigan have voiced concern over the City of Flint’s ability to manage its water system, more than two years since it startled struggling with lead contamination.
Chicago water department employees say racism persists at their workplace despite city efforts to rectify the problem over the past eight months.
Ultraviolet radiation (UV) has become increasingly popular for disinfecting wastewater treatment plant effluent. UV provides safe, reliable, and cost-effective disinfection. However, proper operation and maintenance (O&M) is needed to ensure the best performance. In addition, using best O&M practices extends equipment life.
As wastewater operations grapple with onerous costs and regulations, tools to constantly monitor waste stream conditions have become critical.
Technology for wastewater treatment is an ever-changing thing. But as plants continue to rely on instrumentation to assure effective operations, a new level of diagnostics has emerged.
Despite their best intentions, wastewater operations all over the country have suffered from accidently under- or over-administering treatment chemicals when trying to get effluent into shape. With the proper tools, however, these mistakes can become a thing of the past.
Wastewater treatment operators spend countless hours working diligently to ensure their effluent complies with state and federal regulations. But some common errors can get in the way of their best efforts.
Water utilities are under constant pressure to run more efficiently, often with minimal staff. Utility managers must find ways to save time and money, while continuing to provide excellent customer service. A common area of inefficiency is found within water service shutoff and turn-on events. So how can utilities improve business operations in this area?
Water utilities face many challenges including aging infrastructure, constrained resources and revenue shortfalls. Most utilities use various technological resources to manage their assets and increase efficiency. Resources may include Advanced Metering Infrastructure (AMI), Geographic Information Systems (GIS), hydraulic models, asset management systems, network sensors, Supervisory Control and Data Acquisition (SCADA) systems and billing databases. Unfortunately, those resources are often managed in “silos.”
Last year was full of twists and turns for the drinking water and wastewater treatment industries. What can 2017’s biggest stories tell us about what’s to come this year?
Though the current U.S. EPA administration is boasting about its action to clean up the nation’s Superfund sites, it appears that it has not done as much as implied.
Texas has a problem with radium contamination in its drinking water, according to a new study from researchers at the nonprofit Environmental Working Group (EWG).

In 2017, society made great strides in utilizing the natural resources found in wastewater. If this recent project is any indication, 2018 will see even more efforts to do so.
Wastewater lift stations collect every type of debris. From wipes to t-shirts, from rocks to boards, some strange materials end up in the wet well. Unfortunately, some of these items don’t make it through the pump. Many operators have spent Super Bowl Sunday pulling a clogged pump to remove stringy rag balls or other debris. And in severe cases, sanitary sewer overflows result in regulatory fines.
There are various treatment processes that are used to remove iron and manganese from ground water for potable water supplies. While there are various less common treatment methods used (such as ion exchange and ultra-filtration), most treatment systems for iron oxidize the ferrous state of iron to a ferric state so the solid particles can then be filtered out.
Affordability and maintainability are two of the greatest challenges small municipalities face when constructing and managing sewer infrastructure. With these challenges in mind, it’s important for small cities to choose wisely when investing in a wastewater system that needs to last for 30-60 years.
A new chemical solution has emerged that might help wastewater treatment operations deal with biosolids.

The Internet continues to transform the way business is done, industries are in transition, new markets are opening, and consumer habits are shifting. Even if your architecture is working well now, is it scalable enough to adapt to unpredictable changes?
One afternoon at a waste water treatment facility, an alarm goes off when the water pressure gets too high in one of the tanks. The alarm is set at priority level 4, which means “critical,” but it doesn’t stand out because almost every other alarm at the facility is set at that level. Besides, the operator can’t acknowledge it right away because he’s dealing with several other alarms that went off a few minutes earlier – which he doesn’t yet realize are just “nuisance alarms.”
When it comes time to update, it's a prime opportunity to consider switching over to new software that offers improved functionality instead of dumping more money into just keeping your existing software up-to-date.
