  • Water Treatment System Types and Their Benefits

    Water is one of the most important utilities in the world. It’s used for bathing, cooking, washing clothes, cleaning dishes, and drinking. If you get your water from the city, you trust your tap water to be clean and healthy. It goes through a treatment plant before it reaches you, so it’s perfectly purified when it reaches you—right? Unfortunately, this isn’t always 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 ...

  • Apartment Water Test - Case Study

    We had successfully mitigated this exact situation at another property (Family Tree Apartments] which also had extensive pin hole leaks and water heater failures. Based upon this prior exceptional success, it was clear that the H20 Solutions USA, LLC team was again needed to engineer a solution. H20 Solutions USA, LLC is analysis revealed that the water supply in Greenfield, CAis very hard at 18 ...

  • 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 ...

  • 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 ...

  • Combined application of Pipe Penetrating Radar and LIDAR for large diameter pipe inspection

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR), a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in./450mm) non-metallic (reinforced concrete, vitrified clay, PVC, HDPE, etc.) underground pipes. Light Detection and Ranging (LIDAR) has become an accepted method for ...

  • What’s in those new plastic pipes delivering drinking water?

    Lingering questions leave some concerned about a new generation of plumbing material The calls and e-mails arrive as often as several times a week from people with concerns about drinking water. Some of the callers — who include homeowners, architects and builders — want to know why their water smells like gasoline. Others want to know which kinds of pipes to ...

  • Pipe roughness calibration in water distribution systems using grey numbers

    This paper presents a procedure based on the use of grey numbers for the calibration (with uncertainty) of pipe roughness in water distribution systems. The pipe roughness uncertainty is represented through the grey number amplitude (or interval). The procedure is of a wholly general nature and can be applied for the calibration (with uncertainty) of other parameters or quantities, such as nodal ...

  • Feedwater pipe thinning - Case study

    Purpose Advise owners and operators to inspect and test intermediate temperature feedwater piping for internal wall thinning. Problem While not common, pipe wall thinning has been found in areas of turbulent flow in feedwater piping at intermediate temperatures. In at least one case, severe wall thinning to failure occurred downstream of a feedwater chemical ...

  • 40″ Cold Water Intake Pipe Repair - Case Study

    Global’s Cougar and Falcon ROV systems were mobilized to Hawaii to facilitate repairs on the 40” coldwater pipeline transition section in 500 feet of water off of Keahole Point on the island of Hawaii for the Natural Energy Laboratory of Hawaii Authority (NELHA). ...

  • Heavy Metals Water Testing Powered by DNA

    Water pollution is a worldwide problem affecting developing and developed countries alike. Heavy metal contaminants are one prevalent type of water pollutant. They are persistent in the environment once d is charged and removal from source waters is necessary to ensure a clean drinking water supply. The problem of heavy metal pollution arises from several sources. Heavy metals such as uranium can ...

  • Looking in the Pipes of Climate Adaptation Finance

    I’ve often thought about buying a fixer-upper. There is a certain allure to the idea of reviving the charm of an old home and giving it new life. But I’m also acutely aware that behind the walls and underneath the floors, I’m likely to find a tangle of old plumbing—potentially riddled with leaks, an assortment of pipes and parts, and confusing twists and turns. These ...

  • The Importance of Water Testing After Natural Disasters

    In the aftermath of a natural disaster, particularly earthquakes, infrastructure could be damaged and a safe source of drinking water is often not available. This may be due to damaged pipes or water supplies becoming contaminated. Our colleagues at Oxfamstate; “In the initial phases of an emergency it should be assumed that all water sources are contaminated ...
