Cutting off service to a customer who hasn’t paid their water bill can be a controversial move for many utilities. But a new product that integrates a shut off valve with an ultrasonic meter may make what has traditionally been an all or nothing decision a little easier.
Did you know that two-thirds of the continental U.S. has experienced drought in the last few years? It has left many utilities grappling with water scarcity and the costs of finding new water resources and treatment.
As a country, we’ve come a long way toward providing clean air, water, and land — essential resources that support healthy, productive lives. But we have more work to do to make sure that every American has access to safe drinking water.
Water utilities are responsible for one thing above all: supplying safe drinking water to their populations on a daily basis. In light of the recent public health crisis in Flint, MI, utilities have never been under more pressure from the public to perform this service.
Infrastructure matters. It matters — in big ways and in small — to our country, our economy, our quality of life, our safety, and our communities.
With increasing and urbanizing population, extreme weather events happening with greater frequency, aging infrastructure and work forces, more demanding customers, and significant revenue constraints, it is becoming increasingly difficult for water utilities to ensure that supply consistently meets demand.
A champion of water investment shares four strategies for winning over customers to support both short-term and lasting utility initiatives.
In 2015, California entered the fourth year of a severe drought, the driest it has been since record keeping began in the late 1800s. This historic long-term drought is a problem for every American, regardless of where they live, because it has implications for the economy, society and environment.
The rising marginal cost of producing clean water together with increasing demand and higher expectations of reliability and quality of service leaves utilities facing an uphill challenge — managing aging systems and infrastructure with limited resources.
If there is one lesson to be learned from the Flint crisis, it is this: Our communities will be safer in the long run with no lead pipes in the ground.
The rising cost of water has forced utilities to evolve, in their practices and in the ways they interact with a public asked to pay higher rates.
To combat the presence of PPCPs in waterways, the Metropolitan Water Reclamation District of Greater Chicago has established drop-off points for consumers to safely dispose of unwanted pharmaceuticals.
The U.S. EPA estimates that more than one trillion gallons of water are lost through household leaks every year. It introduced “Fix a Leak Week” to bring that number down.
The U.S. EPA and multiple water groups recently gathered during Water Week 2016 in Washington, D.C. to announce updates to an essential guide for effective utility management (EUM). If utilities aren't already familiar with this document, they need to be.
I sympathize with water and wastewater utilities. Tasked with more responsibility than ever, too often they aren’t supported with the necessary financial resources. To draw a baseball analogy, apropos for this time of year, it's like trying to win the World Series with minimal payroll (capital improvement funds) and old, broken-down players (infrastructure).
The City of Wilmington, Delaware is situated where the Christina River and the Brandywine Creek flow into the Delaware River.
Municipal and Industrial water and wastewater treatment systems present a challenging environment in which the accurate and reliable measurement of liquid flow is essential for cost-effective plant operation.
In municipal and industrial wastewater treatment plants, sludge clarifiers are utilized to separate solids from the water treatment effluent system by introducing air and flocculants. This process results in the sludge rising to the top of the pond or tank and spilling over a weir into a separate collection area.
In oil/gas production, refining and storage operations around the globe, flare gas systems are used to burn-off and dispose of waste, excess or off-gases, and as a safety system. The accurate, responsive and reliable measurement of flare gas is essential in order to assure proper operation of the flare gas system, which protects people and equipment from potentially hazardous combustible gas to maintain a safe working environment and to avoid environmental contamination.
To get the latest on the Promag 400 line of electromagnetic flow meters featuring specialized sensor technology, Water Online spoke with Endress+Hauser’s Flow Product Marketing Manager Nathan Hedrick and Environmental Industry Manager Alan Vance. The two served up details on the sensors’ web capabilities, proprietary Heartbeat Technology, and advanced safety features.
Potable water with very low or no metals and no scale or corrosion inhibitor is used.
Flow measurement instrumentation options abound, and the challenge of picking the right one for a particular application can be daunting.
Supervisory control and data acquisition (SCADA) systems are the digital pulse of water and wastewater treatment plants. Serving as the information hub, SCADA makes the most of the day’s cutting-edge technology and in turn uses it to make the most of the plant’s operations. But how to keep up with a system that evolves as quickly as the greatest minds in the field will allow?
Containerized water treatment solutions eliminate many challenges associated with developing a large-scale wastewater or desalination facility.
PFOS and PFOA are on the EPA’s Contaminant Candidate List 4 (CCL-4). Recently, to provide Americans with a margin of protection from exposure to PFOA and PFOS, the EPA established a health advisory with levels at 70 parts per trillion.
Henrico County, Virginia (The County) utilizes multiple chemical technologies in the sewage collection system in order to control hydrogen sulfide concentrations at key points within the system. The county has strict compliance limits for hydrogen sulfide and was facing growing costs, spending in excess of $1.8 million dollars in 2010.
The process of aeration is used to mix, circulate, or dissolve air into a liquid or another substance. Mechanical aeration can reduce the amount of chemicals needed to treat a body of water by providing the oxygen that bacteria need to function properly. There are two common types of water aeration: subsurface and surface. Although subsurface aeration comes to mind first in discussions of wastewater treatment, surface aeration plays an equally important role in oxygenating liquids.
An industry expert addresses technology and compliance concerns regarding the U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2).
As outlined in earlier articles, increasing public awareness or even seeking legal action are potential tools to help municipalities gain control of the wipes problem. However, many agencies have seen that these strategies are not completely effective in the long term, and they must also employ new technologies to permanently deal with the wipes epidemic.
In August of 2007, the Michigan Department of Environmental Quality issued seasonal ammonia discharge limits for the Coldwater Wastewater Treatment Plant (WWTP), which included a daily maximum ammonia concentration of 2.0 mg/L between the months of May and November.
As part of an ongoing effort to improve efficiency and lifecycle costs across all of its projects, a Municipal Utilities Board in Albertville, Ala., set out to upgrade solids handling at the WWTP and pursue Class A biosolids certification, a U.S. Environmental Protection Agency (EPA) designation for dewatered and heated sludge that contains low levels of pathogens.
It’s long been thought that the presence of iron in drinking water is a cosmetic problem rather than a public health concern. But some scientists are now saying that while the iron itself might not be hazardous to your health, what it does to your drinking water is.
Last year the EPA implemented new regulations entitled “Mandatory Reporting of Greenhouse Gases.” The new regulations called for certain facilities emitting 25,000 metric tons or more per year of specified GHG’s to provide an annual report of their actual GHG emissions. By Allen Kugi, Member Technical Staff, Fluid Components International (FCI)
Water reuse may be the moment’s most talked about treatment industry topic. It’s no wonder that as drought persists in regions throughout the world without sign of subsiding, questions about how we can make the most of our water are being asked.
