Wastewater Measurement Resources

  1. City Solves Reliability And Maintenance Problems For WTP Hypo Feeds 8/13/2014

    A municipal water quality manager reports replacement of sodium hypochlorite (hypo) vacuum feeder units with a more advanced type at one water treatment plant (WTP) has helped allow for continued reliability for chlorination.

  2. Precision Vs. Recall For Predicting Service Line Materials 10/31/2022

    Consider what makes a "good" prediction and the choice to be made between the prioritization of precision and recall. 

  3. Supporting Improved Wastewater Intelligence And Source Control With Real-Time Data Gathering And Event-Triggered Sampling 12/22/2021

    Wastewater can be both a potentially harmful pollutant and a valuable resource and a vital raw material. It could be the potential key to sustainable water consumption. 

  4. Igudan's Water Reuse System Saves Millions In Irrigation Costs 7/13/2023

    Learn how a WWTP overcame the challenge of encountering unidentified wastewater events from unknown sources that impact its processes.

  5. Smart Antenna Technology For AMI 11/9/2020

    When several years of drought subsided and water restrictions were lifted this spring for the city of Round Rock, Texas, residents quickly returned to their pre-drought usage patterns—and as they watered their lawns, filled their pools and used water the way they had before the drought, their monthly bills began to rise. The utility billing office started getting calls from a number of the 33,000 homes and businesses throughout Round Rock.

  6. Understanding ISE Measurements In Wastewater Process Monitoring 3/25/2013

    Analytic measuring technique provides a huge number of procedures to determine the concentrations of substances in an unknown sample, e.g. photometry, titration or mass spectrometry.

  7. How A 'Smart' City Improves Life For Residents, Visitors, And Business 6/1/2017

    Cities that champion infrastructure improvements and embrace connectivity are well on their way to attracting today’s citizens and encouraging growth. Here’s a look at the benefits a smart city provides for its residents, workforce, and visitors.

  8. How Digitalization Can Boost Natural Disaster Resiliency In Municipal Water And Sewerage Treatment 3/28/2019

    Digitalization of the municipal water treatment industry is fragmented today, with instrumentation, control, and automation technologies mixed with manual operational activities. Such infrastructures can be detrimental in cases of hydro-geological events, such as severe storms and earthquakes. The good news: When natural disasters strike, digitalization can help get municipal water treatment back online quickly and effectively.

  9. HRSD Gains New Operational Awareness To Improve Wastewater Operations 6/25/2021

    In southeastern Virginia, Hampton Roads Sanitation District (HRSD) handles wastewater treatment for 1.7 million people in 20 cities and counties. Sea-level rise, unusually high tides, and extreme storms prompted a $1.2 billion program—the Sustainable Water Initiative for Tomorrow (SWIFT) that involves replenishing the Potomac aquifer with up to 100 million gallons of SWIFT Water (water treated to meet drinking water standards and matched to the existing groundwater chemistry in the aquifer) per day, an action that may slow or reduce the impact of sea level rise by slowing land settling, or subsidence.

  10. The Journey To Predictive Maintenance 8/31/2015

    With the digital age fully upon us, it’s time for treatment plants to evolve beyond preventative maintenance and embrace predictive maintenance.
