A Q&A with Gary Wong, chairman of the SWAN North American Alliance
Sampling and laboratory testing are major responsibilities for water professionals. Test results are used for process control, and ultimately to determine that water is safe for drinking, reuse, or discharge to the environment. Regulatory agencies rely on reported results for proof of permit compliance. So, obtaining representative, properly collected and preserved samples is the first critical step to ensure accurate test results.
Water and wastewater utilities must monitor numerous aspects of their systems on a continuous basis. Various instruments are used to measure these processes, producing volumes of data every day. Endress+Hauser is a leading supplier of products and services for process measurement and automation. Water Online spoke with three of Endress+Hauser's experts to find out how data loggers and managers can save costs while providing effective data management.
Ever since Coriolis flow measurement technology achieved mainstream appeal, industry has been fervently striving to take advantage of its benefits. And while Coriolis is clearly a highly advantageous solution for many crucial flow measurement applications, it is not without flaw.
The digital revolution has reached our utilities, but not everyone is taking advantage of how it can, for example, make water and wastewater cleaner, healthier, and more efficient. National news media seemingly report daily on U.S. infrastructure, but they rarely get down in the trenches with the public works professionals who are accomplishing so much. Three of them, who are using the Internet of Things (IoT) to better manage critical assets, tell their stories here.
There is little doubt that America’s infrastructure is aging, and in some cases, operating well beyond its originally intended lifespan. With labor costs representing up to half of the cost of pipe replacement, the key to cost-effective water and wastewater utility strategies revolves as much around labor-saving installation efficiency as it does around the physical performance of a particular material. Here is a look at historic failure rates, causes, and factors to consider when replacing existing water distribution and sewer networks.
Q&A With Opworks™ User And Developers
I became interested in water and the Internet of Things (IoT) several years ago when I had a below groundwater leak at home that resulted in a large water bill. Since I live in the Silicon Valley, CA, the high tech capital of the world, I thought there should be a better way to track water usage so problems can be identified and solved sooner.
Research studies, empirical evidence, and the march of time all suggest that the implementation of next-generation technologies at wastewater utilities is profoundly important, if not imperative, for efficient operations.
