  1. 1. Challenges and Opportunities For Safe Water Supply in Mozambique

    Författare :Nelson Matsinhe; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; service quality; sustainability.; water treatment; water supply;

    Sammanfattning : In Mozambique, despite considerable investments in the promotion of drinking water supplies, the access to quality water of sufficient quantity for the majority of people is still far from optimal. Current official figures report that nearly half of the country´s population and about 45 per cent of urban residents do not have access to safe water. LÄS MER

  2. 2. Aspects of drinking water supply in areas of humic water

    Författare :Talis Juhna; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : The thesis investigated several aspects that are important for drinking water supply from waters with high amounts of humic substance (humic water). The results showed that the composition of humic substances is important in their sorption to aquifer material during surface water artificial recharge through infiltration basins to groundwater.

  3. 3. Decision support for sustainable water security

    Författare :Karin Sjöstrand; Chalmers University of Technology; []
    Nyckelord :decision support; water scarcity; water availability; water security; drinking water supply; multi-criteria decision analysis; sustainability; cost-benefit analysis; marginal abatement cost curves; risk assessment;

    Sammanfattning : Society’s large dependence on water, in combination with climate, socio-economic and demographic changes, places a massive pressure on our freshwater resources. As a result, water crisis, defined as a significant decline in the available quality and quantity of freshwater, is now considered to be among the most critical global risks to society. LÄS MER

  4. 4. Risk Assessment and Decision Support for Managing Drinking Water Systems

    Författare :Andreas Lindhe; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drinking water; risk assessment; decision analysis; water safety plan; water supply; multi-criteria decision analysis; dynamic fault tree analysis;

    Sammanfattning : The vital importance of a reliable and safe drinking water supply makes efficient risk management necessary for water utilities. Risks must be assessed and possible risk-reduction measures evaluated to provide relevant decision support. LÄS MER

  5. 5. 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 :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.
