In order to increase federal spending for the military, President Donald Trump has proposed significant cuts to the U.S. EPA.
The act of sewage blending has long been controversial, with the U.S. EPA at one point scrapping the idea. In Allentown, PA, this controversy is playing out between the municipality and state regulators.
Some of the U.S. EPA’s own employees contacted their senators last month in an effort to get them to vote against the confirmation of President’s Trump controversial nominee Scott Pruitt.
West Virginia lawmakers are considering legislation that would allow more toxic discharges into waterways in the state.
Using fast-track procedures, Congress killed an Obama administration regulation aimed at protecting streams from mining waste earlier this month.
The Trump administration is enacting swift policy changes at the U.S.
In municipal and industrial wastewater treatment, there has been a shift from manual to automatic process control in order to increase efficiency and improve effluent quality. An increasingly popular approach includes installing a variable frequency drive (VFD) to constantly adjust the amount of air injected into the process to control dissolved oxygen, NH4, and/or NO3 in the wastewater treatment. This approach works well from a process control standpoint.
The Water Environment & Reuse Foundation introduces a “bundle of research” to help direct potable reuse and its practitioners reach full potential.
If you feel like you have too much data but not enough understandable or usable information, fine-tuning data collection and funneling it into an integrated data management system may be the way to become more proactive and make better decisions.
Who wants cake? Certainly not treatment plant operators who employ microfiltration and ultrafiltration membranes, and here’s what they’re doing about it.
The multi-electrode sensor delivers an accurate measurement of the full pipe profile rivaling the performance of a full-bore mag meter.
The FPI Mag™ (Full Profile Insertion) Electromagnetic Flow Meter is the only hot tap full profile insertion flow meter available on the market.
The VM V-Cone System’s innovative design delivers repeatable accuracy of +0.5% of rate over a 10:1 flow range under the most difficult flow conditions.
The V-Cone® flowmeter is a patented, differential pressure type flow measurement device.
The M0300 Bolt-On Saddle Flowmeter features a fabricated stainless steel saddle with McCrometer’s unique drive and register design.
Model MW600 Weld-On Saddle Meter is machined to the same radius as the tube on which it is to be installed to provide accurate alignment.
Updates to a seminal document for running water and wastewater utilities as efficiently as possible call for review by those facing new obstacles.
With the change in administration comes a potential paradox for water and wastewater treatment in the oil and gas industry: Will increased production accompanied by decreased regulations call for more treatment technology or less? Either way, the market is poised for change.
The U.S. EPA has updated the list of approved test procedures that can be used to analyze wastewater for compliance under the Clean Water Act.
A new best practices guide from the U.S. EPA provides discharge permit writers and pretreatment coordinators with tips on helping wastewater treatment plants deal with industrial effluent.
With new information on the pervasiveness of nutrient pollution in the country’s drinking water sources, the U.S. EPA has offered lessons on turning the tide.
In the years the U.S. EPA has worked under the Obama administration, the agency has been very active. Depending on your perspective, that may be good or bad. While some see new regulations as necessary to protect citizens and the environment (and to drive innovation in the water sector), others argue that recent actions have been overly restrictive and unduly burdensome.
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.
Summer reading list a bit dry? Drink up these books on the world’s greatest resources — water.
A Request for Startups post on January 3rd on the Y Combinator Blog caught my eye. 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.
While most of the country was seeing red, white, and blue this past Fourth of July, many Florida residents were seeing green.
The U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2) was adopted in 2006 to modify the Safe Drinking Water Act and more tightly control the spread of Cryptosporidium, a microorganism that can cause gastrointestinal infection if ingested. Since its inception, the rule has posed a treatment challenge to utilities that are susceptible to the tiny contaminant. But which utilities are at risk? And how should they approach treatment?
While the term “Water Resource Recovery Facility” may seem like nothing more than a trendy phrase, the name change represents a distinct shift in the role that wastewater utilities can now play.
Conversation at the 2016 SESWA Stormwater BMPs, LID and Green Infrastructure Seminar in Atlanta GA that I attended recently touched upon the idea of computers taking our jobs and ‘Engineering Bots’. This has of course happened in other industries, but I didn’t anticipate it happening in the stormwater planning, design and management world.
Living near water requires that we plan for situations when we have too much of it. Throughout history we have dealt with flooding when weather events exceed “normal” parameters.
Loudoun Water, a water utility serving customers in Loudoun County, Virginia, recently undertook an innovative, green approach to supplying water in the face of game-changing growth and development.
Picturesque Wynn Vale Dam in Adelaide is the site for the City of Tea Tree Gully (CTTG) Council's innovative stormwater harvesting and reuse initiative.
The benefits of Advanced Metering Infrastructure (AMI) are well known in the water industry, but the public is not as aware of what AMI has to offer. With that in mind, industry experts are looking for ways to educate customers about the value provided by AMI.
The Mountain Regional Water District is a Special Service District of the county that was established by the Summit County Commission in 2000 to regionalize water service by consolidating several public and private water companies.
Located in northern California, the Coastside County Water District (CCWD) provides treated water to the scenic town of Half Moon Bay and several unincorporated communities in the area. The system is served by two treatment plants, the Nunes Water Treatment Plant (4.5 MGD) and Denniston Creek Water Treatment Plant (1.0 MGD) and water is distributed through about 100 miles of transmission and distribution pipe.
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)
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?
Changing environmental conditions and increased regulatory oversight have combined to make discharge one of the most pressing concerns for wastewater treatment plants (WWTPs) today. While many plants have found that they need to step up their treatment game to keep up, it can be a challenge to find improvements that are effective and efficient.
It’s just past 10 on a Friday night, and the phones start ringing in the pockets of the on-call collection systems operators. It’s an alarm for another pump clog at one of your sewage lift stations — the second one this week.
