2. 1. Assessment of stormwater and snowmelt quality based on water management priorities and the consequent water quality parameters

   Author : Helen Galfi; Maria Viklander; Jiri Marsalek; Helene Österlund; Jon M. Hathaway; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; indicator bacteria; water quality assessment; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

   Abstract : Stormwater and snowmelt pollution contributes to degradation of quality of the receiving waters. For assessing such impacts, it is effective to focus on specific causes of degradation, as done in this study of the quality of stormwater and snowmelt discharges into the receiving waters serving for supply of raw drinking water and water-based recreation.

4. 2. Assessing and optimizing biofilter performance in drinking water treatment

   Author : Nashita Moona; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-scale biofilters; sterilization.; optical properties; Biofilter; dissolved organic matter; treatment optimization; drinking water;

   Abstract : Biological filtration is a widely used treatment barrier in drinking water treatment plants to ensure the biological stability of treated water in distribution systems. Biofilters remove particulate and dissolved organic matter (DOM) and biodegradable organic matter from water. READ MORE

5. 3. Urban Water Security – Local Conditions and Regional Context : A case study of attitudes and water use behaviour in Windhoek, Namibia

   Author : Therése Sjömander Magnusson; Jan Olof Lundqvist; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; water supply; urban; water management; water demand management WDM ; vattenförsörjning; Namibia; Water in nature and society; Vatten i natur och samhälle;

   Abstract : The world is becoming urbanised. Between 1995 and 2025, it is estimated that the cities and towns of the developing world will have absorbed another two billion people. A majority of these people will be poor and settle down in the unregulated areas. READ MORE

6. 4. Hydrodynamic modelling of microbial water quality in drinking water sources

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

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE
