An infusion of $6 billion in federal funding for critical water infrastructure projects appears to be on the way to some very happy state and local officials. What a great gift!
In the world of water and wastewater, it's not enough to simply get a measurement back on how your system is performing. The non-linear process of water treatment and distribution requires ongoing adjustment and diagnostics based on process and regular instrument analysis. In this Water Online video, Tom Siller, Senior Director for Hach's Software Business Unit, discusses Claros, a new water intelligence system that not only analyzes but looks to fill the knowledge void as we face a generational change in our treatment operator ranks.
A suspended U.S. EPA official is calling out the Trump administration for what she sees as negligence on rules protecting children from lead.
As water and wastewater treatment plant (WTP/WWTP) processes and control systems become more sophisticated, maximizing operator effectiveness becomes more complex as well. A well-planned alarm and control strategy can make a significant difference between valuable decision-making information and confusing, disjointed, data points. This article highlights key strategies for foreseeing problems in advance, fixing them faster, and having a higher success rate by maximizing operator effectiveness.
Water and wastewater treatment applications encompass a wide range of processes, technologies, and physical/chemical methods. Among them, filtration and separation technologies are the core of treatment processes, and in many cases, they can be critical process bottlenecks. Engineering firms, engineering procurement and construction contractors, and end users have high expectations regarding a plant's operation, process design, efficiency, and performance.
There are a variety of costs that are easy to overlook in water treatment. But as Herman Coello, Products Manager for SIEMENS Process Instrumentation, explains in this Water Online video, accurately measuring your flow and treatment parameters can reduce them all. Much-overlooked expenses such as pumping inefficiencies and chemical overdosing can all be reduced to save operating expense.
In September of 2016, Ted Henifin took the first sip of water purified at a pilot treatment plant developed by HRSD (Hampton Roads Sanitation District). Now, the innovative water treatment program known as SWIFT — Sustainable Water Initiative for Tomorrow — is changing the lens through which communities and government officials view wastewater, drinking water, aquifer replenishment, and even fighting sea level rise.
The fate of a water utility in Indiana lies in the hands of a court.
In water plant operations, there’s no such thing as simply maintaining the status quo. Any utility that is not moving forward is falling behind. Whether a water treatment or wastewater treatment plant (WTP/WWTP) chooses to rely on in-house resources or outside specialists, here are some lifecycle management approaches they can use to upgrade control capabilities without compromising performance or return on investment.
Boiler feedwater is comprised of two very important, and increasingly expensive resources: steam condensate return and city (or well) makeup water. The condensate is valuable due to low electrical conductance, purity, and high temperature. The makeup water is valuable because it is being overused and under conserved in many parts of the country, making the cost of water rise in almost all parts of the U.S.

While the laws of physics and chemistry have not changed, the ways that water and wastewater treatment plants (WTPs/WWTPs) are being forced to deal with them certainly have — e.g., disinfection byproducts (DBPs), tighter turbidity standards, harmful algal blooms, and PFAS challenges. Even when plant throughput stays the same, the demands on plant personnel continue to increase. Here’s how evolving toward better workforce management processes can help.
The City of Paramount conducted a pilot study for arsenic, manganese and iron treatment system at their Well 15 site. The onsite pilot test was designed to demonstrate the performance of the Loprest Water Treatment Company treatment process proposed for the new treatment plant.
When it becomes necessary to expand or blend water supply sources, variety is not necessarily the spice of life. Whether new water sources are surface water or groundwater, fresh, brackish, seawater, or water recovered from aquifer storage, they can ultimately impact water treatment plant (WTP) operations and finished water quality — including compliance with the U.S. EPA Lead and Copper Rule.
Prioritizing and funding pressing infrastructure needs can be challenging for water treatment and wastewater treatment plants (WTPs/WWTPs) of any size. The problems are particularly stressful for smaller utilities where a thin layer of upper management staff wears an inordinate number of hats. The good news is that funding assistance does exist — if you know where to look for it and take the right steps to apply for it.

Just when we thought the jurisdictional and regulatory issues concerning the federal Clean Water Act and the resulting implications could not get more complicated, recent developments have put that possibility to rest.
With any technology, new capabilities are typically associated with new requirements and responsibilities. While the bottom line of customer billing based on advanced metering infrastructure (AMI) essentially remains the same as it was with manual meter reading, the technology introduces some new “technical issues” regarding data security. For example, while more frequent RF data collection enables added layers of data insight, it also creates a new channel for potential data exposure.
The so-called "brain-eating" amoeba, a water-based threat that poses a risk to water utilities, has taken another life.
Groundwater in Southeastern coastal Virginia is depleting due to over-drafting without intentional replenishment. This phenomenon makes the Potomac aquifer susceptible to saltwater intrusion as well as land subsidence, or the gradual settling or sudden sinking of the earth’s surface. The Hampton Roads Sanitation District responded to these issues by using groundwater augmentation as a way to recharge the aquifer, prevent saltwater intrusion, and potentially increase ground elevation.
“We have too much data” is the refrain we continually hear from water utilities. It’s no surprise that managing data from multiple sources and turning it into business insights presents a daunting challenge; however, data influx does not have to be a burden. When managed well, there’s no such thing as too much data, especially if your business is implementing a big data strategy — a topic that has implications and reach beyond the scope of this paper.
