  • Dissolved Solids and Water Purification

    To make drinking water palatable, the level of dissolved substances (TDS) can’t be too high, but it also can’t be too low Water quality metrics are needed to ensure that surface and groundwater – common sources of water for human consumption – are free from contaminants and pollutants. The level of dissolved solids, also commonly referred to as total ...

  • Surface/bathing water monitoring (Denmark) - Case Study

    In order to find the possible fecal sources to the sporadic high concentrations of bacteria, the municipality of Hjørring (DK) has set up a BACTcontrol in the ditch to monitor the E.coli levels. For this purpose the BACTcontrol is built into a movable trailer and powered by solar panels. This allows the BACTcontrol to run continuously (6 samples per day) for 7-14 days depending on the ...

  • Flow Measurement in the Cold

    Measuring flow can be a very delicate process depending on the needs of your operation. For instance, measuring flow in cold weather locations is an extremely difficult task. When outdoor temperatures are near or below freezing, it makes it nearly impossible to measure flow as you would in normal circumstances, meaning you must find alternative solutions so that your operation continues to have ...

  • Report: Circular economy offers solutions to water shortages worldwide

    A shift to a circular economy could help save more than 400 billion m3 of water every year While oceans cover more than two-thirds of our planet, only 2.5% of all water on earth is fresh water. With billions of humans seeking water for their personal, agricultural, and commercial needs, the demand for sustainable water resources is at an all-time high. A recent report by ...

  • Improving governance in transboundary cooperation in water and climate change adaptation

    Climate change adaptation in water management is a water governance issue. While neither climate change nor water respects national borders, adaptation in water management should be treated as a transboundary water governance issue. However, transboundary water management is, in essence, more complex than national water management because the water management regimes usually differ more ...

  • Temporal and thematic trends in water, sanitation and hygiene (WaSH) research in Pacific Island Countries: a systematic review

    Pacific Island Countries (PICs) lag behind global trends in water, sanitation and hygiene (WaSH) development. We conducted a systematic search of all English language papers (published before February 2015) about WaSH in PICs to evaluate the state of the peer-reviewed literature and explore thematic findings. A total of 121 papers met the criteria for full-text review following an initial ...

  • Adapting the IWA water balance to intermittent water supply and flat-rate tariffs without customer metering

    The International Water Association water balance is an approach applied worldwide for determining and analysing water losses in water distribution systems (WDS) up to the point of customer metering. Thus, water losses occurring ‘before’ a customer meter are at the expenses of the water utility while water lost or wasted ‘after’ the meter is paid for by the customer. This applies to systems ...

  • Investigating unaccounted for water and its components in Zomba City water supply system, Malawi

    This study assessed Unaccounted for Water (UFW) in Zomba City, Malawi in 2009 and quantified its real and apparent loss components. The study was carried out in the period January–May 2009 and focussed on three selected water supply zones (Airwing, Malonje and Sadzi) especially for determination of the components of non-revenue water (NRW). Field measurements of flow and utility records formed ...

  • Measuring Wastewater Below Ground

    Measuring wastewater is one of the most difficult water management tasks that exists. While some wastewater flows are easy to access, others are very hard to measure because they are in open channel conditions and are below grade. If you need to measure below ground wastewater flow, there are a few factors that you need to consider to help you choose the right tool for the job. With a ...

  • Addressing urban water scarcity: reduce, treat and reuse – the third generation of management to avoid local resources boundaries

    Urban growth leads to geographically concentrated demand for water and food – and to growing volumes of wastewater and organic waste. Left unattended by city authorities, both local and planetary resources boundaries for water and nutrients will be transgressed. A novel partly dynamic ‘flexible water balance’ is developed to explore ways to address a looming water crisis. A systems-based flow ...
