  1. 1. Aspects of historical data and health criteria for drinking water network replacement strategies

    Författare :Annika Malm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pipe rehabilitation; water distribution network; cost-benefit analysis; Pipe replacement; leakage control; lifetime distribution; pipe failure; health risk; strategic planning; asset management;

    Sammanfattning : The drinking water distribution network represents a major proportion of the investments and capital assets of a water utility. Consequently, qualified insight into future replacement needs provides water utilities with a foundation for financial planning. LÄS MER
