  • Component-holistic condition assessment of water distribution networks

    The work presented herein presents an expanded methodology for imprinting the condition of an urban water distribution network (WDN). Even though the majority of past research efforts related to WDNs deal with water mains (WMs), only a small part of the research studies have considered house connections (HCs) in the analysis and very few researchers have examined how the failure of pipe ...

  • F-Gas Regulations - An Update

    How does the latest F-Gas Regulation affect refrigerant leak detection? January 2014 saw the revised EU Regulation of F-Gases following publication of a draft proposal by the European Commission at the end of 2012. The much anticipated regulation changes aim to strengthen the existing F-Gas Regulation and to ‘encourage’ the industry to move towards a HFC free market and use of ...

  • An Overview of the F-Gas Regulation Proposals

    By now you should have an appreciation of F-Gas regulations and what it means to you. But in case you don’t, here’s a quick overview in relation to leak detection. Why have the F-Gas regulations come into force? Fluorinated greenhouse gases (F-Gases) are potent greenhouse gases that contribute to global warming and are sometimes referred to as High ...

  • Locating Geomembrane Liner Leaks under Waste in a Landfill

    Abstract An Electrical Leak Imaging and Monitoring (ELIM SM) survey was used to locate leaks under 2.5 meters of stabilized waste in an active geomembrane-Iined landfill. The landfill is lined with two 2-mm thick HDPE geomembranes that are separated by a geonet drainage layer. The primary liner is covered with 600 mm of drainage sand and 2.5 meters of stabilized waste for a total cover ...

  • Non-Revenue Water – A Growing Issue for Water Utilities

    Each day, billions of gallons of water are lost worldwide to various factors, including leaks, water main failures, theft and metering inaccuracies. Not only does this represent the waste of a precious resource that many people do not have reliable access to, it also represents a massive amount of lost revenue for the utilities that provide water services. In developed nations, ...

  • Identifying Leaks from Natural Gas Pipelines at a Safe Distance

    The use of natural gas, of which methane is the principle component, is increasing worldwide. According to the American Petroleum Institute methane meets 24% of U.S. energy demand and heats over 50% of all U.S. households. It also has many industrial uses, such as the manufacture of chemicals like ammonia, methanol, butane, ethane, propane and acetic acid; it is also an ingredient in products as ...

  • San Diego County Water Authority Manages Steel Pipelines

    Utilities across the country are experiencing an increased rate of pipeline failures. In addition to problems precipitated by an aging water infrastructure, a lagging economy is affecting large-scale capital projects needed for repairing, replacing, and improving infrastructure. With funding gap estimates ranging between $200 billion and $1 trillion over the next 20 years, utilities must find ...

  • Capturing the fugitives: Reducing methane emissions from natural gas

    The rapid expansion of natural gas development in the United States has been a double-edged sword. While natural gas supporters are quick to point out its economic benefits and green attributes—natural gas produces roughly half the carbon dioxide emissions of coal during combustion—this isn’t the whole story. Natural gas comes with environmental consequences, including risks to ...

  • What’s New? Maximizing The Life Of Aging Metallic Pipelines With Modern In-Line Technology

    Maximizing the life of aging pipelines has long been a challenge in North America. Owners of large diameter water and wastewater infrastructure face particular condition assessment challenges, owing to factors such as financial constraints, environmental concerns and access restrictions, which compound the problem. While desktop studies can help identify pipes with a likelihood and consequence of ...

  • Proposals on carbon-related border adjustments: prospects for wto compliance

    Recently the practice of border adjustment in international trade has attracted much interest in the context of climate change. The risk of carbon leakage, the competitive disadvantage of industries in countries introducing a cap on emissions and the desire to induce large greenhouse gases emitting countries to join international climate change mitigation actions are the main reasons for ...
