Pay Today Or Pay Tomorrow? Choosing The Right Clarifier Materials
Submerged clarifier components force a trade between purchase price and long-term corrosion risk. Galvanized steel, coated steel, and stainless each carry different failure modes, maintenance burdens, and ownership costs.  Continue Reading..

SWAN Corner: What Does Resilience Really Look Like In A Water Utility?
Ask a water utility what keeps them up at night and you'll usually hear two kinds of answers. There's the slow build — deteriorating infrastructure or underinvestment, for example — and then there are sudden impacts such as a main break or cyberattack. At the same time, utilities must balance competing needs among residents, industry, and the environment. These pressures often do not operate in isolation.  Continue Reading..

South Africans Living Through Water Cuts Blame Corruption And Neglect, Not Just Broken Pipes — Study
Going without piped water for weeks or even months has become a reality for many South Africans. The residents of Madibeng, meaning “place of water” in Setswana, in the country’s North West province, are no exception.  Continue Reading..

Coastal Restoration Is In All Our Hands
While on vacation, my tour group visited the Palo Seco Mangrove Reforestation Project, where we spent a morning planting mangrove seedlings as part of its coastal restoration program. As I lowered my seedling into a hole, it hit me: As a writer, I had covered coastal restoration projects many times, but this was the first time I was actually taking part in one.  Continue Reading..

Benefits Of Mobile DAF And MBBR Treatment For Food And Beverage Wastewater
Food and beverage plants in violation must correct discharge within days, yet permanent fixes take far longer. Rented treatment changes how plants handle that gap.  Continue Reading..

England Needs 120% Of Normal Rainfall To Come Out Of Drought This Winter — Storms Won't Fix That Yet
Groundwater supplies much of the drinking water in southern and eastern England, but it fills slowly, over months and years. A hot summer is a big splurge with lots of withdrawals, but a dry winter means the deposits needed to repay that spending never arrive. That’s why a dry winter can do more damage to our water supplies than a heatwave.  Continue Reading..

How A Tiny Water Utility Pieced Together Millions In Infrastructure Funding
While no major municipal water utility has ever claimed to be overfunded, it is much easier to cover the cost of large projects when it can be spread across hundreds of thousands of residents. But this is a stark contrast to the mathematical reality of smaller utilities like the Madison Community Services District (CSD). Its small size can make it difficult to attract the attention of those who control the purse strings for major projects.  Continue Reading..

Understanding Biofilm Through Oxidative Chemistry
Biofilm is one of those water treatment problems that can look deceptively simple. Microorganisms attach to a surface, multiply, and begin building a community. The natural response is to disinfect, apply enough oxidant to kill the organisms and maintain a residual strong enough to keep them under control, however in practice, it is rarely that straightforward.  Continue Reading..

BactoSense ID Cuts Wastewater And Bathing Water Bacteria Testing From Days To Minutes

Lausanne-based bNovate Technologies has sold 500 systems worldwide performing more than a million automated microbiological measurements per year. The company has now launched BactoSense ID, an automated microbiological monitoring solution that detects and quantifies key bacteria, including E. coli, coliforms, and enterococci, in wastewater and bathing water in under 60 minutes, compared with 18–72 hours for traditional lab testing. BactoSense ID opens new addressable markets for bNovate.

Research To Standardize Pathogen Monitoring For Water Reuse

A new study from The Water Research Foundation (WRF) is underway to help utilities and regulators evaluate pathogen concentrations in treated wastewater effluent for potable reuse applications. Led by Carollo Engineers, with the Southern Nevada Water Authority, San Diego State University, CDM Smith, and Trussell Technologies as co-investigators, WRF project 5309, Developing a Protocol for Evaluating Pathogen Concentrations in Secondary Effluent, will run over 24 months to close a gap in how the industry assesses treated effluent.

Ofwat-Funded Smart Alarm Project Hits Key Milestones

A water innovation project set to transform how control room alarms are managed has reached three major milestones, moving a step closer to helping utilities identify and respond to operational issues more effectively.  

IDOM Engineering Recognized With MUSE Design Award For Ras Tanura Wastewater Treatment Plant

IDOM has participated in the development of the detailed engineering of a new industrial wastewater treatment plant (IWWTP) for Ras Tanura Refinery for SEPCOIII, the main EPC contractor and IDOM’s client, aimed at improving effluent management and promoting water reuse within the refinery complex.
