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 — in terms of utilizing data from analytical instrumentation, refining process control, and responding to regulatory standards — is falling behind.
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 United States.

The water utility in San Angelo, TX, is urging customers who paid their water bill online during the summer months to immediately get a new card.
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 over the past few decades certainly have. This ranges from increased focus on disinfection byproducts (DBPs), to tighter turbidity standards for charting Cryptosporidium removal, to emerging challenges with harmful algal blooms (HABs) and per- and polyfluoroalkyl substances (PFASs). Even when plant throughput volume stays the same, the demands on plant operations personnel continue to increase. Here’s how evolving toward better workforce management processes can help.
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.

The refinement of computing power into ever smaller devices, and the untethering of communication from hardwired networks in favor of radio frequency (RF) communication, has fueled an explosion of new internet-connected commercial and consumer capabilities labeled the “Internet of Things” (IoT). Under that concept, clustered data collection, calculation, and control applications now extend from full industrial process automation to residential HVAC, lighting, and water meters.
The history of commercial online transactions is riddled with horror stories about data security breaches. Think Equifax, Target, Yahoo, Uber, Sony PlayStation … the list goes on. How can a utility maximize the benefits advanced metering infrastructure (AMI) offers for more efficient data collection and management, without having to worry about seeing its name on the front page of tomorrow’s newspaper?
Water utilities around the country are inviting the public to think the unthinkable in a campaign kicking off October 10 known as “Imagine a Day Without Water”.
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.
By now, most of the utilities managing the 80 percent of U.S. water meters not yet capitalizing on advanced metering infrastructure (AMI) have heard about the advantages offered by the 20 percent of utilities that are. Unfortunately, utilities large and small still cite a variety of reasons delaying their step up to AMI productivity — including smart meter installation costs, lack of in-house expertise, and capital budgets for IT support.
