SEWERS & SEWER LINE MAINTENANCE RESOURCES

• A Handy Tool For Wet Well Maintenance: Cutting Through The FOG

  Blame our fast food diets or restaurants’ negligence for what’s going down the drain. Whatever the cause, fats, oil, and grease (FOG) accumulation has become a pervasive problem for wastewater treat­ment plant collection systems.

• Why It’s Smart To Increase Your Sewer Network Monitoring

  Effectively managing hundreds of thousands of miles of sewer network is not an enviable task. And with ever changing industry regulation, stricter statutory targets, additional compliance and a growing abundance of technology, that task could easily be regarded as insurmountable. How can you ever know exactly what’s going on throughout your entire network? It’s impossible. Or is it?

• The Contractor’s Song: Building Pipelines In Rock!

  This month our topic fits in well with a whole genre of music and it was hard to pick just one song to weave into this column, so I didn’t. The hits just kept coming to mind so consider this discussion of building pipelines in rock to be an homage to all things rock and roll!

• House Committee Makes Down Payment On Clean Water Needs

  The House Transportation & Infrastructure Committee is moving forward with a measure that would invest $3.7 billion in critical wastewater and stormwater infrastructure. These resources will help communities across the country struggling with sewage spills, inadequate sanitation, and destructive urban flooding.

• WWEMA Window: Governmental Policy And The Impacts On Construction Costs

  There are a few current governmental policies that have impacted the construction cost of water and wastewater infrastructure over the last several years. Some are older policies that were established many years ago and some are newer policies that were implemented to help U.S. manufacturers compete in these markets against foreign manufacturers. There is some discussion now in Washington to implement more policies such as $15 minimum wage and revisions to the Made in America requirements for purchases using federal money, both direct and indirect.

• Is Water Odor A Challenge?

  Turning your water tap on only to be encountered by a terrible stench is arguably one of the worst ways to start your day. Your immediate reaction may be to assume that your water supply is contaminated, but there are myriad reasons why your household water has suddenly developed a pungent odor.

• Large Florida Utility Saving Money Through Innovation

  After spending decades and millions of dollars rehabilitating sewer pipes across its service area, a large coastal utility embarked on a pilot pipe condition assessment program for 25,000 linear feet in areas prone to high unwanted infiltration rates.

• New Pipe Installation Fails Multiple Acoustic & Pressure Testing Until Electro Scan Finds Water Leak Location

  Balfour Beatty was unable to determine why a new pipe installation, a 600mm (24 inch) diameter Cement Mortar Lined Ductile Iron, 170m (560ft) pipe length was unable to pass multiple hydrostatic pressure test. Using multiple above ground and in-pipe acoustic sensors, data correlators, data loggers, and listening sticks, no leak locations could be found.

• Standards For Testing And Certifying Cured-In-Place Pipe

  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.

• Use Of Low Voltage Conductivity To Conduct A 10km (30,461 LF) Inspection Of Legacy Cured-In-Place Pipe (CIPP) For A Leak Assessment Project

  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).
