  3. 22. Hydrodynamic modelling of microbial water quality in drinking water sources

    Författare :Ekaterina Sokolova; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; faecal contamination; QMRA; faecal indicators; pathogens; risk assessment; microbial source tracking; Bacteroidales; E. coli;

    Sammanfattning : The faecal contamination of water sources can cause waterborne disease outbreaks among drinking water consumers. To design drinking water treatment and minimise consumer health risks, knowledge on source water quality is needed. LÄS MER

  4. 23. Insufficient water supply in an urban area - case study : Tegucigalpa, Honduras

    Författare :Zairis Aida Coello Midence Balthasar; Jan-Erik Gustafsson; Berit Balfors; Mats Lannerstad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water supply; Honduras; SANAA; Tegucigalpa; water utility;

    Sammanfattning : Tegucigalpa, the capital of Honduras, has experienced an unsatisfied water demand during the last three decades. The state owned water utility in charge of the water supply of the country, SANAA, has faced this deficit by providing an intermittent water supply. LÄS MER

  5. 24. Challenges and Opportunities For Safe Water Supply in Mozambique

    Författare :Nelson Matsinhe; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :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

  7. 25. Environmental management of water systems under uncertainty

    Författare :Christian Baresel; Georgia Destouni; Vladimir Cvetkovic; Keith Beven Beven; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water Resources Engineering; Water engineering; Vattenteknik;

    Sammanfattning : Hydrological drainage/river basins constitute highly heterogeneous systems of coupled natural and anthropogenic water and pollutant flows across political, national and international boundaries. These flows need to be appropriately understood, quantified and communicated to stakeholders, in order to appropriately guide environmental water system management. LÄS MER
