  4. State And Local Government Saves 25% In OPEX With Modeling Software 10/12/2020

    Cities use sewer models to avoid capacity issues, mitigate overflows, and address asset deterioration.

  5. Maintenance Is King: How To Keep Your Pipe Rehab Gear At Peak Performance 4/10/2023

    Proper maintenance can help you extend the life of your pipe rehab gear and avoid costly repairs. Explore some tips for protecting your equipment and avoid downtime from unexpected damage.

  6. The Duperon® FlexRake®: Inventing A Product That Defined A Segment 2/23/2018

    In 1993, the Duperon® FlexRake® entered the market as the first multi-rake wastewater screen to operate without a lower sprocket, bearing or track. Designed by Duperon Corporation founder Terry Duperon, the patented equipment reflected his belief that mechanics should operate as simply as possible. The result was a mechanically-cleaned bar screen that consisted of just three main components — screen, raking device and drivehead. Despite its simplicity, the unit quickly proved to be far more reliable than other, more complicated designs. Paired with the industry’s first five-year warranty in wastewater, the Duperon® FlexRake® soon became a benchmark for low maintenance and ease of operation. 

  7. Maintaining Continuous Water Service During Critical Infrastructure Upgrades 5/29/2024

    Discover how Hydra-Stop’s insertion valve provided new control points without impacting service to surrounding customers.

  8. EPA Researchers Develop Tool To Assess Onsite Non-Potable Water Reuse For Buildings Across The U.S. 6/2/2021

    Increasing pressure on water resources has led to greater water scarcity and a growing demand for enough clean water. Many communities across the country have initiated, or are in the process of developing, centralized systems for planned water reuse. Water reuse is the concept of intentionally recycling, treating, and reusing alternative water sources. Federal government agencies and the water user community are coordinating their efforts to advance the adoption of water reuse and ensure the security, sustainability, and resilience of water resources. The National Water Reuse Action Plan (WRAP) describes these collaborative actions.

  9. KLa Jet Aerators/Mixers For Large Diameter Equalization Tanks 6/5/2014

    Many municipalities are facing the challenge of having to equalize large volumes of storm water sometimes mixed with raw sewage in order to continuously meet their permit limitations. The equalized flow is stored during a storm event and then slowly diverted to the treatment facility when influent flows return to normal levels.

  10. Mitigating Environmental Impact Of Gold Mine's Wastewater Through Ozone Oxidation And Aquifer Re-injection 9/5/2018

    Installing and operating an ozone oxidation system for wastewater remediation at a gold mine located in a remote region of Alaska is full of challenges.
