  • Process to Estimate Sanitary Sewer Pipe Remaining Life Provides MWWSSB Remedial Decision Information

    ABSTRACTA condition assessment study for the Water Works and Sanitary Sewer Board of the City of Montgomery’s (MWWSSB’s) West Catoma Interceptor (WCI) was conducted in 1998 and 2003. The WCI was evaluated in 1998 using core sampling, closed-circuit television, and manhole (MH) inspections. Approximately 193 MHs and 65,000 linear feet (LF) of pipe were inspected. A subsequent study conducted in ...

  • Making Every Drop Count: Unitywater uses leak detection as a foundation for condition assessment

    It stands to reason why many utilities respond to leaks only after they receive a call about water gushing from a street or a complaint from a customer about a damp basement, or other signs of visible leakage. Human nature reflects the adage that is often easier to respond to an ...

  • From Pilot Studies to Full Scale Plant

    Natural gas is widely used as a primary energy source and is one of the most efficient fuel source. For this reason, more and more gas is utilized exceeding existent production facilities. Oil and gas companies therefore expand there measures and step behind borders finding and exploit new resources. One area of major interest is the Barents Sea, a remote area far from industry and civilisation. ...

  • Less Reactive, More Proactive

    OPERATORS EMBRACE INLINE TECHNOLOGIES TO ASSESS THEIR METALLIC FORCE MAINS Historically, it has proven difficult to assess the condition of pressurized mains that carry sewage, especially those made with ferrous material. Metallic force mains have special operational challenges that ...

  • GPR goes underground: Pipe Penetrating Radar

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR) either robotically or by manned entry to reveal wall thickness, delamination, voids, and other conditions that enable more precise determination of pipeline integrity and verifications for trenchless technology rehabilitation. PPR, when applied to pipe-bursting applications, can ...

  • Tackling Non-Revenue Water by Identifying Small Leaks

    Small leaks sink big ships – the same can be said for large-diameter pipes in utility networks. While large leaks or ruptures are seen as newsworthy stories accompanied by images of water flowing down the streets; smaller leaks can often be more devastating. Left undetected, they can add up over time, contributing significantly to ...

  • The hidden threat

    Many decisions that are made at the design stage of engineering can have a major impact on safety and cost during the operational stages. This is especially true of pipe supports. Corrosion under pipe supports (CUPS) is a growing problem and a particular threat to pipework integrity, as Laza Krstin, Principal Consultant at ABB Consulting, explains. For many operating companies, extending the ...

  • Advanced Condition Assessments: The benefits of using Pipe Penetrating Radar

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in/450 mm) nonmetallic (reinforced concrete, vitrified clay, PVC, HDPE, etc.) underground pipes. The key advantage of PPR is the unique ability to map pipe wall thickness and deterioration including ...

  • NORMs contamination treatment using Ivey-sol technology

    NORMs (naturally occurring radioactive materials) are found almost everywhere, and many natural materials, such as the earth’s crust, contain such radioactive materials. So what happens when oil and gas activities such as petroleum refining and natural gas extraction, disturb such radioactive material? They can alter the natural background radiation — the radiation that we are ...

  • City of tarpon springs assesses critical ductile iron force main

    Across the United States, there are many thousands of water and wastewater utilities that serve populations less than 50,000. Although the majority of attention surrounding aging infrastructure focuses on the challenges of large utilities, these small utilities are often faced with greater challenges. Smaller utilities often have fewer resources – both financial and personnel – ...

  • Short Showers Replace Deep Baths: Drought Conditions Changing the Way Society Thinks About Water Infrastructure

    While proactive water conservation is a smart way for consumers to react to climate change, the crisis puts increased pressure on water utilities to better manage their resources and pipeline networks. Change is in the air. One only needs to check the daily news to understand why climate change, drought and water infrastructure have become frequent buzzwords heard around the water ...

  • January Anaerobic Digest

    San Francisco Bay Region, California: ABC Digester Operator Training Course The American Biogas Council (ABC) has organized a 3-day, hands-on operator training course, February 6-8, 2018 in the San Francisco Bay area, that focuses on digester operations overall with an additional emphasis on renewable natural gas (RNG) and codigestion at wastewater treatment plants. Each morning starts ...

  • ALBANISA Oil Spill Equipment Setup - Case Study

    As a part of the Bolivarian Alliance for the People of Our America (acronym in Spanish: ALBA), Nicaragua has received funds to build a new oil hub in the Caribbean. The hub will be available for oil companies in order to store their products before reaching its final destination. By doing that the profit will be increased as the costs for transportion is reduced. The updated environmental ...

  • Tackling waste in the sands of the Sahara

    When gas was discovered in the mid Sahara areas of North Africa in the 1990s Andy Ive was asked by BP to help set up the water and waste infrastructure for what amounted to four small towns 600 km into the desert. No local infrastructure at all existed for the waste and water to be produced by 2-3000 workers. IVE overcame sandstorms, extreme heat, poisonous snakes and patented a novel solution to ...

  • Ping-ping, what’s that sound? Acoustic fiber optic technology helps identify problematic water mains

    With the deteriorating state of many aging water mains found in cities across North America, urbanites are frequently witnessing unexpected plumes of water erupt as man-made geysers in their own metropolitan backyards. While natural geysers are awe inspiring, urban geysers are much less so, due to their destruction to property, roads and the environment. Because an uninterrupted water flow is the ...
