    The storm was a one-in-ten-year event. But it’s one that the engineers at TasWater, the water and wastewater agency for Tasmania, realized the people in the region would remember for a long, long time.

  2. A More Efficient Approach To EPA Stage 2 DBP Compliance
    4/20/2018

    Everyone wants pathogen-free drinking water, and adding chlorine is a great way to get it. Unfortunately, the dirtier a water treatment plant (WTP)’s raw water inflow — in terms of natural organic matter (NOM) or microbial organisms — the more disinfection byproducts (DBPs) the chlorination process will generate in the form of trihalomethanes (THMs) and haloacetic acids (HAAs). Those DBPs increase the risk of non-compliance with the U.S. EPA’s Disinfectants and Disinfection Byproducts Rules. Choosing the right instrumentation to measure NOM through spectral absorption coefficients (SACs) can have a big impact on treatment strategies — in terms of both costs and compliance performance.

  3. Remote Monitoring For Water Quality And Public Health

    New technology helps utilities meet the challenges of maintaining a safe and adequate public water supply.

  4. Four Ways Food And Beverage Companies Can Outmaneuver Amazon
    5/28/2019

    Food and beverage distributors aren’t seeing much competition from Amazon, but they soon may. Here are four steps all food and beverage companies should take to prepare for this potential threat.

  5. Beyond The Buzzword: How Utility Operators Can Use Big Data For Better Asset Management, Operations, And Customer Engagement
    5/7/2018

    Big Data is more than a marketing buzzword. It’s become an essential tool for helping utility operators prioritize capital investments, manage network assets, and provide a higher level of service to customers.

  6. Better Asset Maintenance Through Better Data Management
    3/21/2019

    The more a water utility knows about its current operations, the better equipped it can be to make more informed decisions about upcoming maintenance and capital replacement programs. Here are several key approaches to identifying cost-effective ways to make merging historical asset data and current operational data as the next step toward building a stronger, more resilient utility.

  7. 7 Strategies For Avoiding 'Boil-Water' Emergencies
    6/6/2019

    It’s every water distribution manager’s worst nightmare — the dreaded boil-water advisory. Even when faced with aging infrastructure, there are ways to alleviate timing and complexity concerns about emergency pipeline repairs in advance. Use this seven-step checklist to become better prepared to deal with water main break emergencies and to forestall the need to issue a boil-water advisory.

  8. Evaluating Field-Testing Options For Nutrients In Streams
    3/26/2018

    Aside from having to deal with weather, mud, and the occasional slippery rock, there are key issues related to sample quality that can make testing water specimens from the field a bigger challenge than lab testing. That is why, when it comes to confidence and accuracy in onsite testing for nitrates, nitrites, phosphates, pH, and more, there’s nothing like using the right tools to do the job on the spot. Here is a quick checklist of trials, tribulations, and potential solutions for streamside sampling.

  9. Setting A Precedent: American And Others Work To Ensure Oregon Water System Meets Rigorous Seismic Safety Standards
    8/9/2019

    Most agree that Oregon, with its breathtaking mountains and rugged coastline, is a scenic wonder. Yet the geologic forces that make it so spectacular also make it one of the most earthquake-prone spots in the country.

  10. How To Predict And Prevent CSOs And SSOs
    5/9/2019

    Combined and sanitary sewer overflows are natural hazards for wastewater collection systems. Without a comprehensive solution to monitor troublesome conditions, overflows can be triggered with little warning and lead to expensive and embarrassing situations. Fortunately, versatile analytical systems that capitalize on existing wastewater collection infrastructure hold promise for avoiding such negative impacts.
