Sewers & Sewer Line Maintenance Resources

  1. Standards For Testing And Certifying Cured-In-Place Pipe 6/23/2021

    It is estimated that nearly 75,000 miles of wastewater and water pipelines have been lined with Cured-In-Place Pipe (CIPP), with nearly $3 billion spent annually on the trenchless renovation method, worldwide. Recognizing the growing use of CIPP and inability of CCTV inspection to accurately or consistently certify trenchless rehabilitation as defect-free, this paper chronicles the emergence of new guidelines to test, certify, and accept CIPP lining projects, using Focused Electrode Leak Location (FELL) inspection.

  2. Use Of Low Voltage Conductivity To Conduct A 10km Inspection Of Legacy Cured-In-Place Pipe For A Leak Assessment Project 6/23/2021

    In 2017, the Institute of Underground Infrastructure (IKT), Gelsenkirchen, Germany, utilized low voltage conductivity to test a variety of trenchless Cured-In-Place Pipe (CIPP) short-liners to locate and quantify leaks, several of which were utilized in a multi-million rehabilitation project in Kansas City, Missouri (USA).

  3. Sydney Water Trial Project Using Low Voltage Conductivity To Assess Sewer Pipe Water Tightness 6/22/2021

    Worldwide water utilities and smart cities are adopting new technologies to replace legacy technologies that have been the mainstay to assess existing pipe conditions and accept new installations as watertight. This white paper includes a detail review of existing assessment techniques, project findings, technology overview, and field results fom each project area included as part of Sydney Water’s trial project evaluation of FELL technology.

  4. Sarasota Gets A 'Lift' In Fight Against Sewage Leaks 5/11/2021

    Sewage spills in Florida are frequent. A newspaper report in 2019 found deteriorating sewers released 1.6 billion gallons of wastewater within a decade in communities throughout the state. Daytona Beach, Jacksonville, and even tony Boca Raton, labeled the “Beverly Hills of Florida” with its yacht clubs and fancy restaurants, were among the regions impacted by failing systems.

  5. Rust Is A Slow Poison 5/6/2021

    With the escalating call for water wells across the globe, much of it driven by the increasing use of water-well water in agriculture and construction, water-well drilling is now an $85-billion industry. 

  6. America Is Bordering On A Water Infrastructure Crisis 4/21/2021

    There is no disagreement — water is a precious asset. Without water, there is no path to survival or sustainability on the planet. Cities, counties, states, industry, trees, plants, crops, animals, and individuals cannot survive without adequate water resources. In America’s overall drive to sustainability, water is one of the most critical components. Yet, America’s water infrastructure is in significant disrepair. Because it has been ignored so long, some warn that America is entirely too vulnerable.

  7. Xylem's Flygt N 3312 Electric Pump Provides Non-Clog Sewer Bypass Solution 4/12/2021

    Electric submersible pump is another game-changing rental solution

  8. Hydro-Brake Drop Cuts Corrosion, Complexity And Cost For Saudi WWTP Project 2/2/2021

    Saudi Arabia's National Water Company needed to transport sewage from Riyadh to the wastewater treatment plant (WWTP) at Al Haer. Read the full case study to learn how Hydro International worked with ILF Consulting Engineers to develop an alternative design using three Hydro-Brake® Drop systems.

  9. 7 Tips For Better, Faster Municipal Sewer Cleaning 12/22/2020

    Industry experts provide guidance to optimize cleaning efficiency, while preventing or quickly resolving problems such as tough blockages and “blown toilets”

  10. Real-Time Decision Support System Exceeds Expectations -- Buffalo Cuts CSOs By 450 Million Gallons, Reducing Consent Agreement By $145 Million 8/4/2020

    Recognizing the generally inadequate stormwater capabilities of their existing combined sewer system, the Buffalo Sewer Authority (BSA) began to prepare a comprehensive watershed improvement plan with grey, green and smart sewer solutions.
