87. Preparing Wastewater Samples For SARS-CoV-2 Analysis 8/12/2021

    Wastewater is a focal point for public health professionals evaluating levels of COVID-19 community infection. Here are some considerations on the use of membranes for efficient SARS-CoV-2 virus water sample preparation.

88. How To Bridge The Wastewater Infrastructure Gap 8/28/2025

    Across the country, wastewater systems are reaching the end of their intended lifespans. Most treatment plants were designed to operate for 40–50 years. Now, many are now overdue for major upgrades or full replacements. This issue is compounded by decades of declining investment.

89. Join Hydro International For The Vortex Flow Controls In Practice Webinar 11/11/2021

    In this follow-up webinar Technical Product Manager, Phil Taylor will demonstrate in more detail how to select and design a Hydro-Brake using our free online design tool. The Hydro-Brake is one device that should be in every stormwater engineer’s toolbox. Hydro invented the vortex valve back in the 1960’s and has led the world in its development and design ever since.

90. How Flow Technology Can Ease The Inflow And Infiltration Headache 12/20/2024

    This article will explain why rain-dependent inflow and infiltration (RDI&I) measurement often fails and how to produce the level of data quality that can detect, understand, and manage it.
