WASTEWATER MEASUREMENT RESOURCES

• New Study Reveals Gaps In The Methods Used To Assess Chemicals In Oilfield Wastewater

  A new study led by researchers with Colorado School of Mines exposes limitations with the current methods used to detect chemicals in oilfield wastewater and offers solutions to help regulators make better decisions for managing this waste stream.

• Should You Trash Your Flow Meter?

  Generally speaking, market research reports aren’t terribly exciting reads, but they are at times enlightening. Studies on how specific technologies are being applied can reveal trends for the industries they serve — for example, flow meters in water and wastewater. I recently came across some interesting analysis on the subject, homing in on what they reveal about our corner of the world.

• The Benefits Of A Venturi Meter

  With the introduction of new measurement technologies and the myriad of performance claims from sale literature, it’s easy to lose sight of the important elements that an effective flow meter offers no matter what technology is used. Long known for their longevity, reliability, and long term performance, Venturi meters provide the widest variety of measurement options in piped systems for liquids, gas, steam, and mixed media of any metering technology – all while offering the highest degree of traceable accuracy.

• Water Monitoring's Triple Threat: Bad Habits, Bad Readings, Bad Results

  When water and wastewater plant operators can’t get accurate flow measurements or analytical readings — or lack confidence in their instruments’ readings — it creates challenges with the process. When substandard water goes to homes and causes a boil order, or discharge pollutes a lake or reservoir, the resulting bad press, fines, and potential lawsuits erode public confidence. Avoiding these kinds of problems is rooted in good preventive maintenance habits.

• All-in-One SCADA

  Serving roughly 35,000 people, the Town of Natick Water/Sewer Division remotely monitors 2 water reservoirs, 32 sewer lift stations and 2 drinking water treatment plants. By Chris Little

• Versatility Of Thermal Mass Flow Meters

  There are many well documented flow meter technologies that are essentially trying to accomplish the same thing: measure fluid flow rate. Some of the technologies that are entrenched in the market, such as flow meters that utilize differential pressure as the measurement principle, are well understood by customers. Thermal mass flow meters however, such as the Magnetrol® Thermatel® TA2, are a rapidly growing technology that is continuously evolving.

• WWEMA Window: The Importance Of Early Design System Integration

  The water/wastewater industry is about to be hit, and in some cases already has been hit, with funding for projects through the Bipartisan Infrastructure Law (BIL). Monies are starting to flow from the federal government into State Revolving Funds, or SRFs, to assist municipalities with upgrading an aging infrastructure.

• TasWater: Saving Oysters With Data

  At 10am on August 24, 2017, a customer in Midway Point, a small suburb outside of Hobart, Tasmania, reported a sewage spill on his property. Midway Point stands adjacent to Pitt Water Nature Reserve, home to rare birds, butterflies, and the largest oyster lease in Tasmania, covering some 14 hectacres. In late August, Pitt Water oysters, prized for their briny flavor and consistency, were just coming into peak condition.

• Water And Wastewater Control Systems: Overcoming A Tidal Wave Of Security Concerns

  It was reported in Verizon’s 2016 Data Breach Digest that a hacktivist group associated with Syria hacked into an anonymous water utility’s control system and changed the levels of chemicals being used to treat tap water. An unnamed water district, dubbed the Kemuri Water Company (KWC), experienced unexplained patterns of valve and duct movements over at least a period of 60 days.

• The Evolution Of Smart Utilities

  Advances in telecommunications, automation, and data analytics are changing the relationship between utilities and their customers.
