  3. 7. Arsenic in Alluvial Aquifers in the Meghna Basin, Southeastern Bangladesh : Hydrogeological and Geochemical Characterisation

    Författare :Md. Aziz Hasan; Prosun Bhattacharya; William Burgess; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alluvial aquifer; groundwater; arsenic mobilisation; geology; Meghna basin; Bangladesh; Water engineering; Vattenteknik;

    Sammanfattning :  Elevated levels of arsenic (As) in Bangladesh groundwater has emerged as a massive calamity exposing a large population to the risk of As toxicity from drinking water sources and agricultural products. Holocene alluvial aquifers in the delta- and flood-plains of the Ganges-Brahmaputra- Meghna (GBM) river systems are severely affected by high levels of As in groundwater. LÄS MER

  4. 8. Development of Decision Support Tools for Urban Water Supply Management in Uganda

    Författare :Frank Kizito; Roger Thunvik; Patrick Ogao; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decision support systems; Participatory decision-making; Geovisualization; Non-revenue water; Geostatistics; Action research; Water engineering; Vattenteknik;

    Sammanfattning : In this study, five real-life problem situations were used to explore the challenges of developing and implementing decision support tools for management of an urban water utility in Uganda. The study sought to explore how the degree of adoption of formal decision support tools in practice, generally perceived to be low, could be improved. LÄS MER

  5. 9. Water supply management in an urban utility : A prototype decision support framework

    Författare :Frank Kizito; Roger Thunvik; Kalanithy Vairavamoorthy; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decision support systems; Geographic information systems; Participatory planning; Urban water supply management; Decision support framework; Action research; Water engineering; Vattenteknik;

    Sammanfattning : In this study, four real-life problem situations were used to explore the challenges of developing and implementing decision support tools for planning and management within an urban water utility. The study sought to explore how the degree of adoption of formal decision support tools in practice, generally perceived to be low, could be improved. LÄS MER

  7. 10. Water Supply in Tanzania and Performance of Local Plant Materials in Purification of Turbid Water

    Författare :Nancy Marobhe; Gunno Renman; Gunnar Jacks; Msafiri Jackson; Tapio Katko; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antibacterial effect; Coagulant proteins; Vigna unguiculata; Parkinsonia aculeata; Ion exchange; Tanzania water supply; Water engineering; Vattenteknik;

    Sammanfattning : Water supply services in urban and rural areas of Tanzania were reviewed and specific studies were carried out on water supply and on purification of turbid water sources using locally available plant materials in rural villages of Singida Rural District. The review showed that large proportions of urban and rural populations in Tanzania face acute water supply problems mainly due to poor planning, implementation and management of water supply projects, including an inability to address social, technical, operation and maintenance and financial issues.
