  • Using Alternative Methods in Greenland - Qaqortoq, Greenland - Case Study

    In 2012, Leif Koch A/S had the honor of performing leakage detection as well as being witness to the repairing process. At the time, Nukissiorfiit Qaqortoq lost 5-7 m3 of water each day on their district heating plant. Unfortunately, nature of the pipes made it impossible to find the leaks without the use of alternative methods, which is why the supply company decided to contact Leif Koch A/S. ...

  • Optimizing DMAs' formation in a water pipe network: the water aging and the operating pressure factors

    Dividing a water distribution network (WDN) into district metered areas (DMAs) is the first vital step towards pressure management and real losses reduction. However, other factors of water quality such as the water age must be taken into account while forming DMAs. The current study uses genetic algorithm (GA) optimization methods to achieve the desired WDN segmentation conditions in terms ...

  • Forming DMAs in a water distribution network considering the operating pressure and the chlorine residual concentration as the design parameters

    Dividing a water distribution network (WDN) in the optimal district metered areas (DMAs) formation is one task that usually troubles water utility managers. The present paper utilizes optimization methods to achieve desired segmentation conditions in terms of (a) operating pressure reduction, thus reducing the system's real water losses and (b) residual chlorine concentration reduction thus ...

  • Simulation News

    Our STS DP6 smart probe for the Radeye SX has gone down well with customers and is now in use in the UK and Europe. This is the 2nd smart probe built by STS wher the user can utilise their own real survey meter to carry out their contamination training without requiring a dedicated instrument. ...

  • Risk-based sensor placement methods for burst/leak detection in water distribution systems

    The optimal placement of sensors for burst/leak detection in water distribution systems is usually formulated as an optimisation problem. In this study three different risk-based functions are used to drive optimal location of a given number of sensors in a water distribution network. A simple function based on likelihood of leak non-detection is compared with two other risk-based functions, ...

  • Investigating nitrogen removal using simultaneous nitrification-denitrification in transferring wastewater through collection networks with small-diameter pipes

    This study evaluates the removal of nitrogen compounds from wastewater in modified, small diameter gravity slope (SDGS) pipes during its conveyance. A 13-meter long, closed loop, wastewater collection network was designed and built at laboratory scale. The modified SDGS consists of Polyvinyl Chloride (PVC) tubes with perforated plastic netting fixed to the inner surfaces, to enhance biofilm ...

  • Investigating the management of unaccounted for water for Lilongwe Water Board, Malawi

    Lilongwe Water Board (LWB) is currently unable to meet Lilongwe City's water demand as evidenced by low supply coverage (65%) and intermittent water supply in the city. One of the major challenges is high levels of unaccounted for water (UFW) reported at 37% (2012), higher than the recommended 23% for developing countries. This study, done in Lilongwe City (Areas 15, 18 and 28), investigated ...

  • Our drinking water systems are a disaster. What can we do?

    In the wake of the Flint, communities turn to innovative technology and financing to prevent the next crisis. People in developed countries turn on the tap and safe drinking water flows, a dramatic health benefit they tend to take for granted. That complacency was dramatically disrupted last year when children in Flint, Michigan, started testing positive for lead poisoning and the ...

  • Top 10 Valve Considerations for Pressure Management Zones/DMA’s

    For basic pressure management or more advanced modulating pressure management, water suppliers create a network of District Metered Areas (DMA’s) or smaller, more manageable pressure management zones. The DMA or pressure zone gives the ability to measure flow and control pressure, when a Pressure Reducing Valve (PRV) ...

  • Evaluation of statistical sampling for the assessment of residential consumption totals in water distribution networks

    The paper provides insights into stratified sampling, a standard statistical technique that may be employed to assess domestic water use in water distribution networks. The basic idea is to use only a few meters to provide inference on the total water consumption of a network or of a district metered area through the knowledge of some additional stratification variables, such as household ...

  • A comparison between different techniques for water network sectorization

    Water network partitioning represents one of the best methodologies for improving water balance and pressure control of a water distribution system in order to reduce water leakage. These techniques can be applied with greater effectiveness defining a smaller permanent network district, called a District Meter Area (DMA), achieved by the insertion of gate valves and flow meters. If the DMAs are ...
