Traditional municipal wastewater treatment plants typically rely on conventional tests such as Total Suspended Solids (TSS) and possibly Volatile Suspended Solids (VSS) to attempt to quantify biomass.
Fairmont, Minnesota, known as the City of Lakes, is located in Martin County in southern Minnesota. The city’s water treatment plant serves a mix of customers including approximately 3,900 residential taps, 500 commercial and 17 industrial customers. Looking to the future, Fairmont city leaders began to investigate upgrading the city’s water treatment plant in 2010. The existing plant had been in operation for well over 70 years and relied on gas chlorine for disinfection.
From Nevada to South Dakota and now Tennessee, cities across the U.S. are installing the AMERICAN Flow Control® ALPHA restrained joint, because it saves labor, time and money. Introduced almost a year ago, ALPHA is used on AMERICAN’s Series 2500 4- to 12-inch Resilient Wedge Gate Valves and American-Darling and Waterous fire hydrants.
The need for private partnership in wastewater management has been evident for some time. As a result, there are a number of ways that private players are now involved in wastewater management. For instance, there are plant management specialists, collecting specialists, and technical specialists.

Water from cooling towers attracts and absorbs airborne contaminants on a continuous basis. Typically, 85% of suspended solids in cooling water and hot water loops are smaller than 5 microns. Scientific studies have shown that these small particles (5 microns and less) are the adherent contaminants fouling the water loop and process cooling system.
The Ecomuseum Zoo is home to the most impressive ambassadors of Quebec’s wildlife. All residents of the Ecomuseum Zoo are there for a special reason: orphaned, injured or born under professional human care, each of them could not return to the wild. Hence, they have found a forever home at the zoo.
Amid growing concerns around algal bloom, industrial operations are under pressure to stop using phosphorus-based water treatment technology. But transition to an alternative can be daunting.
If passed, a new piece of bipartisan legislation would provide technical assistance to rural wastewater treatment systems that need help in complying with federal regulations.
The U.S. EPA has a job to do despite having its financial and human resources trimmed by the new presidential administration. Three U.S. EPA Office of Water directors, presenting at the 2017 Water & Wastewater Equipment Manufacturers Association (WWEMA) Washington Forum, laid out action plans for addressing the nation's most pressing water-quality threats in a manner that can (or must) achieve results efficiently.
Micropollutants like PPCPs are known to pass through waterways and contaminate the environment. Some wonder what threat they pose as they find their way into biosolids and, eventually, into our soil.
Researchers from Iowa have developed a system that utilizes algae for wastewater nutrient removal and gives utilities a chance to offset costs with the process.

Cities all over the country have been prioritizing clean water through a variety of different programs and the City of Brotherly Love is among the ranks.
Election season is in full swing and while it may not be the “hottest” topic being debated amongst presidential candidates, the topic of water isn’t being ignored as we approach November. Several candidates have addressed the challenges plaguing water and wastewater systems nationwide.
For years, I’ve been standing on my deck in San Francisco, looking south to Silicon Valley for innovation in water efficiency. But I’m starting to realize that I might have been gazing in the wrong direction. Maybe I need to turn around and look north, over the spires of the Golden Gate Bridge, toward the Emerald Triangle in Humboldt, Mendocino and Trinity counties, the hotbed of California’s newly legalized commercial cannabis production.
More than 20 years ago I wrote a Master’s Thesis about software tools that could be put together with EPA SWMM to create a toolbox for very long term continuous simulation for stormwater and watershed simulations. I was inspired at the time by Dr. William James who was my advisor for that research.
During the long campaign, you ran on a platform of change, and since the election, you have charted a course toward improving our nation’s infrastructure. I urge you to focus some of that change and a significant portion of those infrastructure improvements on the one issue at the center of survival for all Americans, regardless of whom they voted for — water.
It’s no secret that municipalities across the country are facing budget constraints.
It may seem farfetched, but the reality is that many Americans don’t have regular access to clean drinking water.

The blogger talked about the need to prepare for things to get worse with regard to climate change, and called for applications for funding from those working on new technologies that could inexpensively produce clean water.
As part of its Long Term Control Plan to reduce combined sewer overflows (CSOs) to the Merrimack River, the City of Nashua, NH constructed a new Screening and Disinfection facility (SDF) to reduce untreated discharges of CSOs to the Merrimack River.
As our society continues to embrace digital technology, it’s fair to say that the world of water utilities will be, a major beneficiary of this revolution.
New York City treats 1.3 billion gallons of wastewater a day across its 14 wastewater treatment plants. The city has seen a precipitous drop in fecal coliforms, with the NYC Department of Environmental Protection (DEP) reporting that fecal coliforms per 100 mL of water has fallen from 1,000 in 1972 when the Clean Water Act was passed to closer to 10 as of 2009.

While most of the country was seeing red, white, and blue this past Fourth of July, many Florida residents were seeing green.
California is home to some of the world’s most creative minds, top universities, productive farmland, groundbreaking industries — and one of the most epic droughts. The state has endured five years of drained reservoirs and groundwater reserves tapped so aggressively that the land subsidence caused by pumping has been literally seen from space. This indicates in no uncertain terms that it’s time to get all hands on deck. Private companies, universities, irrigation and drainage districts, municipalities — it’s time to pull together into public-private partnerships to address water challenges that face California and so many other regions of the world.
Last month I tipped my hat to America’s rural water districts in the blog post Rural Water Systems: Dancing Backwards and in High Heels.
