  1. 1. Hydraulic Modeling and Quantitative Microbial Risk Assessment of Intrusionin Water Distribution Networks Under Sustained Low-Pressure Situations

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Maryam Shakibi; [2022]
    Nyckelord :drinking water distribution network; EPANET; hydraulic modelling; low pressure; pathogen intrusion; Quantitative Microbial Risk Assessment QMRA ; distributionsnät för dricksvatten; EPANET; hydraulisk modellering; lågtryck; patogen inläckage; Kvantitativ mikrobiell riskbedömning QMRA ;

    Sammanfattning : Drinking water systems aim to remove, reduce, and prevent microbial contamination in water by usingmultiple barriers from catchments to consumers. Water distribution networks are vulnerable tocontamination from external sources if they lose their physical or hydraulic integrity. LÄS MER

  3. 2. A Quantitative Microbial Risk Assessment Associated with Cross-Connections in the Drinking Water Network in Combination with Hydraulic Modeling

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Fatin Alzuhairi; [2022]
    Nyckelord :EPANET; QMRA; Water distribution network; Health risk analysis; Cross-connections and backflow; Low pressure; Water quality; Simulation; Pathogen; EPANET; QMRA; vattendistributionsnät; hälsoriskanalys; korskoppling; lågtryck; vattenkvalitet; simulering; patogen;

    Sammanfattning : Drinking water companies have the technology and responsibility to deliver safe and high-quality drinking water to the water distribution systems network (WDN). However, many events within the WDN, such as cross-connections and backflow, might degrade water quality and pose public health risks to consumers. LÄS MER
