  • What 2017 holds for Energy from Waste in the UK

    The UK’s EfW industry has enjoyed two decades of stable investment under the public private partnership (PPP)/public finance initiative (PFI) regime. This has led to a reduction in the amount of biodegradable household waste sent to landfill via the construction of local authority-backed EfW plants and contributed to an increase in recycling rates by incorporating facilities that remove ...

  • Geostatistical techniques for approximate location of pipe burst events in water distribution systems

    This paper focusses on the customisation and further enhancement of the recently developed data-driven methodology for the automated near real-time detection of pipe bursts and other (e.g. sensor faults) events at the district metered area (DMA) level. Assuming the availability of pressure/flow data from an increased number of sensors deployed in a DMA, the aim is to: (i) overcome the ...

  • Transient tests for locating and sizing illegal branches in pipe systems

    In pipe systems illegal branches can take away remarkable water resources with negative effects from both the economic and technical points of view. Difficulties in pointing out illegal branches by means of steady-state pressure and discharge measurements are mainly due to the fact that, of course, such systems are not active according to a regular time schedule. In this paper the possibility of ...

  • Typical Sensor Location Considerations

    The sensor mounting location within a space may be dependent on many variables. There are no specific formulas since each application will have it’s own determining factors and priorities. These include, but are not limited to: source of gas: Is the source a combustion exhaust from a vehicle or furnace or a vapour from a tank spill, pipe leak, or faulty valve? density of ...

  • Utility locating at a Gasoline station case study

    As part of an Phase II Environmental Site Assessment at a gasoline station, GeoView was tasked with locating and mapping the  utilities within the boundaries of the property. The utilities included electrical lines, communication lines, PVC and metal water lines, sewer lines and fiberglass fuel lines. The property did not have any as-builts to reference. As standard procedure, GeoView ...

  • Effects of the Location of Broken Prestressing wires wraps in structural integrity of a damaged PCCP

    Abstract Breakage of prestressing wire wraps is an indication of damage in Prestressed Concrete Cylinder Pipe (PCCP) due to corrosion, hydrogen embrittlement, overloading, and manufacturing defects. The strength of the damaged pipe is not only related to the number of broken prestressing wire wraps but also to the location of the break regions along the length of the pipe. In this paper, a ...

  • Intake Pipe Repair

    Major problems can cause catastrophic damages to a facility’s operations. The accumulative cost of: repairs, labor, and downtime can add up. This 24 inch diameter intake pipe, located at a U.S. Power Plant, was leaking above the ground just below the disc valve. The plant’s maintenance engineers needed a proven, reliable and economical solution to fix this ...

  • Preventing & Thawing Frozen Pipes

    A “how-to” guide on preventing and thawing frozen pipes. As temperatures drop below freezing around the country, it’s important to be informed of the cold weather’s effect on your water pipes. When temperatures are below freezing, pipes in unheated areas are subject to freezing causing messy, and often expensive issues. Just one burst pipe running at 4-8 ...

  • Leak behaviour in pressurized PVC pipes

    The correct definition of the leak law, i.e. the relationship between the leak outflow, the total head at the leak and other relevant parameters such as the pipe material, can seriously affect the accuracy of the numerical models used for the management of water distribution systems, either if they are used to forecast the leakage reduction by pressure management or to locate and size the leaks ...

  • Plugging `hot` pipes in extreme environments

    Some of the world's most intricate infrastructure is found in power plants, chemical plants, refineries, and other factories that use and combine industrial chemicals. The piping for fuel, chemical transport, water supply, and cooling needs is typically very complex and subject to high temperatures and pressures. And since plants are harsh environments, it's a given that piping needs regular ...
