Combining CFD And Physical Modeling To Evaluate Water Treatment Plant Performance
Hydraulic modeling has no doubt benefited greatly from computational fluid dynamics (CFD), but physical modeling retains importance and even outperforms CFD in certain aspects. So which method should be relied upon? The answer is both.
Integrated Solutions Drive Resource Recovery And System Resiliency
Traditional approaches or wait-and-see tactics, which at times can save the day, too often result in missed opportunities for incremental improvements that could act as building blocks of a long-term strategy. Integrated solutions can reveal this strategy road map for a resilient and reliable water infrastructure system.
Gain Control Of Your Data
For those entrusted with the responsibility of supplying vital water and wastewater services to their communities, it is both the worst and the best of times. It is the worst of times because water challenges are intensifying, stressing infrastructure that is already badly in need of renewal. Around the world, the water system’s vital signs, including leakage, main breaks, and wastewater overflows, reflect a system in urgent need of investment. Yet we cannot simply spend our way out of these challenges, regardless of how they are financed, without intensifying the burden on struggling ratepayers.
50+ Links To Assist Small, Stressed Water Utilities
While any drinking water or wastewater treatment operation can be challenged by demands from changing seasonal conditions or regulatory requirements, those pressures can quickly compound for personnel forced to wear multiple hats at small- to medium-sized utilities. Here are scores of links to helpful resources for such operators for the municipalities and consulting engineers who work with them.
PWSA Reduces Customer Request Fulfillment From 4 Months To 14 Days
Due to recent LCR exceedances, PWSA faced skyrocketing customer requests on top of the order to replace 7% of their roughly 18,000-33,000 lead service lines every year. In addition, their Lead and Copper Compliance (LCR) and Lead Service Line Replacement testing program (LSLR) required immense amounts of manpower. These two events combined to require thousands of point-of-use kits to be collected and tested every year. They looked to 120WA to solve the challenges of siloed data sources, kit delivery and pickup, lab coordination, and distribution of results.
Denver Water Gets Approval To Fast-Track Removal Of Lead Service Lines
In December, the Environmental Protection Agency and the Colorado Department of Public Health and Environment approved Denver Water’s proposal to develop and successfully launch its Lead Reduction Program over the next three years. The program will ultimately take 15 years to complete.
The Drive Towards Digital Transformation
It seems that everywhere that you go in the water industry at the current time, somebody is talking about digital transformation…or if we go back five minutes, it was Water 4.0…and 10 minutes ago (it seems), it was “smart water.” These are all very well used buzzwords that the industry is destined to think about for a short-term and then promptly forget about. In reality, though, we as an industry have been hit by a number of different concepts for a number of different technological aspects for a good number of years now. For almost as long we have had a term for all of this — “widgets.”
Smart Water Networks And The Choices Ahead
Many water utilities continue to evaluate the costs and benefits of investing in smart metering to reduce operational costs and help recover revenue from water losses. Smart metering can also provide customers with more granular consumption data to help them protect their property from water damage and better manage their water expenses.
Water Loss Control — From Audit To Action
Non-revenue water loss is a problem from coast to coast, but California has taken a lead and set an example — with resources from AWWA — by adopting and sharing best practices to help solve the issue.
Moneyball For Water And Wastewater Treatment
The movie and sports term has infiltrated the business world and has important implications for the water/wastewater industry.
