  1. Neptune's R450™ System Helps Get Feet Off The Streets Of Laredo 8/21/2015

    The city of Laredo, Texas, had been walking to read its 67,543 water meters – 59,138 residential and 8,405 commercial accounts – using a manual method that took up to ten staff on the streets nearly an entire month to read to meet a monthly billing schedule. With the dawn of advanced metering infrastructure (AMI) systems, the City began their search for the right metering solution for the department’s needs.

  2. Consultant's Corner: Top 5 Requirements for Good Modeling 12/17/2015

    Dr. Jon Wicks, CH2M’s Global Technology Leader for flood risk modeling, shares his thoughts on the requirements for good modeling, building on discussions held at the recent Flood Modeller Suite Conference.

  3. Innovyze Announces Support For WSA05-2019 v4.1 11/24/2021

    The recent release of InfoAsset Manager 2021.6 now offers support for the Water Services Association of Australia (WSAA) WSA05-2019 version 4.1 Conduit Inspection Reporting Code. This extends support to the existing legacy versions of WSA05-2013 v3.1, WSA05 2008 v2.2 and WSA05 2002. The Australian codes used to describe conduit condition bear some relationship to the codes used in EN 13508-2:2003 Conditions of drain and sewer systems outside buildings Part 2: Visual inspection coding system, which is also supported in InfoAsset Manager.

  4. UV Treatment Upgrades In Wales 8/26/2025

    In order to improve the treatment performance (because of the continued cost to maintain compliance), and ensure that it would eventually have the treatment capacity to meet future population growth equivalent of up to 225,000, Swansea WwTW was in need of an equipment upgrade.

  5. FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications? 4/9/2018

    Measuring the level of tanks used to hold fluids for custody transfer can be expensive. This is not due to the cost of the measurement instrumentation, but to what inaccurate measurements can cost the company. Picking the right instrumentation for applications is important. Which radar level technology should you choose for tank gauging in custody transfer applications? Frequency Modulated Continuous Waveform (FMCW) or pulsed Time-of-Flight (ToF or PToF).

  6. An Integrated, Data-Driven Approach To Water Management 4/20/2021

    Defining a sustainable digital strategy and employing solutions in a phased manner can result in multiple productivity, maintenance, reliability, and cost benefits for water utilities.

  7. Replacement Vacuum Feeders For Hypo Treatment End Heavy Feeder Maintenance Burden At WWTP 4/30/2014

    The instrumentation supervisor for the City of Baltimore, MD’s 150-MGD Back River wastewater treatment plant (WWTP) reports that replacement of problematic vacuum feeders with more advanced vacuum feed units has ended heavy maintenance burdens associated with sodium hypochlorite (hypo) treatment of plant effluent.

  8. Indiana Wastewater Monitoring Program: Sampling Community Sewersheds For SARS-CoV-2 1/20/2021

    A community wastewater system can provide valuable information about public health conditions in an anonymous and rapidly accessible manner. One area where this is especially powerful is infectious diseases, which are shed into wastewater systems. In response to the global COVID-19 pandemic, the scientific community has rapidly mobilized to determine if wastewater monitoring for SARS-CoV-2, the virus that causes COVID-19, could be detected and quantified in wastewater streams and sludge.

  9. Using IoT-Based Tank Level Monitoring For Volume Measurement 9/22/2020

    Level monitoring systems has successfully triumphed every implementation. Their deployments allow the users to measure the level of liquid stored in a container of any shape, size, orientation, or material. Powered with the advanced telemetric technology of Internet of Things, these systems measure liquid level without making any contact with the liquid and transmit the readings to a comprehensive platform suite.

  10. Aeration Basin Air Flow Monitoring At A Stockholm Wastewater Plant 12/20/2013

    At a wastewater treatment plant in Stockholm, Sweden, each aeration basin has several diffuser systems. Each diffuser system requires individual air flow monitoring and independent control. The air flow pipes leading to the diffusers typically do not have much straight run of pipe. This makes accurate measurement of the air flow more difficult. In addition, the air flow coming from the compressors is inconsistent
