Like many cities within the Dallas-Fort Worth metroplex, the City of Coppell experienced water quality challenges at different periods throughout the year. In particular, the City had difficulty maintaining adequate chloramine residuals at the 1.5 MG Southwestern elevated storage tank during the warmer summer months when outdoor watering was restricted to conserve water.
Located in north-central Montana, the City of Havre is located in a geography that sees summer temperatures over 100°F (38°C) and winter temperatures that can plunge as low as -40°F (-40°C) accompanied by sustained arctic winds of over 20 mph. These dramatic swings in temperature can wreak havoc on disinfectant levels in the summer by creating a “stratified” tank environment conducive to pathogen growth and allow for ice formation in the tank during the winter. Ice formation can lead to tank coating and appurtenance damage as large chunks of ice can suddenly drop from a higher tank elevation and create catastrophic tank damage. The City of Havre realized that adding simple mechanical mixing to their newly refurbished 3.5 MG West Water Tank would solve both the potential summer water quality and winter asset protection issues.

One of the most commonly used measurements in the water and wastewater industry is pH. A measurement of how acid or alkaline a substance is, a pH reading can instantaneously indicate a problem with the water. Another common and useful measurement is oxidation-reduction potential (ORP). Treatment facilities use ORP sensors to optimize disinfection and biological nutrient removal processes.
Utilities have relied on numerous instruments for process control and monitoring for many years. But in today’s world, instrumentation is more crucial than ever. Most treatment facilities, pump stations, and other system components are automated to some extent. Instrument failure or inaccuracy may result in serious public health or environmental consequences. Resilient instruments can power through adversity and keep utilities running smoothly.
Vermont is bulking up its drinking water for PFAS by adding three substances to the warning.
Accurate flow measurement is critical for process control and regulatory compliance. Flow meters are essential instruments for water and wastewater facilities, installed at multiple locations throughout entire systems. For the most part, these are permanent installations. However, portable flow instruments prove beneficial in certain situations.
As demand on water resources rises, will there be a mad rush to grab up the nation’s last untapped water resources?
The city of Buhl, Idaho, obtains all of its drinking water from groundwater sources through multiple wells. Prior to 2009, the city did not treat the groundwater but only added chlorine in the form of bulk 12.5% sodium hypochlorite to provide a disinfectant residual. A combination of factors including: changes in EPA and state DEQ regulatory requirements, growth of the residential population and growth of the industrial food processing customers forced the City to build a new water treatment plant to provide filtration to address the naturally occurring arsenic present in the groundwater.
Water has never been more in demand, and innovative approaches to improving water security have never been more imperative.

A lot has changed over the past 15 years. Back in the early 2000s, many utilities weren’t interested in understanding what was in their water beyond the contaminant and disinfection byproduct levels they were regulated to comply with. But as Pat Whalen, President and CEO of LuminUltra, explains in this ACE 2018 Water Talk interview, a steady stream of ongoing education and the modern data storage and analytics that cloud computing provides, has developed some rabid fans eager to explore the microbiology of their water systems.
Historically, most fire hydrants sit idle after they are installed. They were there for that one day that hopefully never shows up. But in today’s connected world, fire hydrants are becoming an important asset in understanding the water distribution system, allowing utilities to monitor their water system operation and predict leaks.
The Upper Trinity Regional Water District (UTRWD) is a conservation district created by the State of Texas in 1989 to provide water, wastewater, solid waste and storm water services to numerous towns and cities approximately 50 miles northwest of Dallas. In 2010, the UTRWD installed three 2,000 pound per day (PPD) chlorine equivalent Microclor® OSHG systems. The systems continue to provide UTRWD with a reliable supply of hypochlorite for disinfection in a manner that is less expensive and less risky than gas chlorine or liquid bulk hypochlorite delivered via truck or rail through such a heavily populated area.
Recently, I had the opportunity to tour a unique and innovative facility, the Bureau of Lab Services (BLS), the “water quality heartbeat of the Philadelphia Water Department” (PWD), as described by BLS director Gary Burlingame.

The key to high rate clarifiers such as inclined plate settlers is flow distribution says Tom Grubb, Regional Manager with Meurer Research. “Each inclined plate is like a miniature little sedimentation basin,” Grubb told Water Online in a recent Water Talk interview at AWWA’s ACE 2018. “To get good effluent quality, it’s critical that you have the same flow to each plate.”
Much like investing in water infrastructure, the country often overlooks the pressing need to invest in a skilled workforce to manage these systems. Nearly 1.7 million “water workers”construct, operate, and maintain water systems found in every region, whether employed in utilities, engineering firms, or other industries. And many water workers are in short supply due to a wave of retirements and a lack of younger talent, even though they earn more competitive wages, tend to only need a high school diploma or less, and develop valuable skillsets over time.
