  • Securing safe drinking water supply under climate change conditions

    Water suppliers worldwide are challenged by climate variations, but so far only the qualitative change in boundary conditions has become clear but not yet the degree and impact on the water supply systems. Short-term quality changes in surface waters can, e.g. be caused by extreme rainfalls after dry periods. Longer heat periods without rain can induce middle-term quality changes in surface ...

  • Laboratory Management - Integrated Sampling the Key to Safe Water Supply

    Leading water suppliers use Laboratory Information Management Systems (LIMS) to integrate the sample collection and analysis process, helping to maximize the efficiency of these programs. Drinking water suppliers around the world face unique challenges: They must deliver the most essential ingredient for life on a grand scale, while also navigating complex issues surrounding public safety, ...

  • A decision support system for water supply emergency management with multiple sources

    The construction of water transfer projects brings new challenges to water resources management, especially in water supply security with the use of multiple water sources. However, the operations of water diversion and water supply have been considered in separation in practice. In particular, there are few decision support systems (DSS) designed to tackle the challenges in emergency planning ...

  • Water supply methods in Ancient Thera: the case of the sanctuary of Apollo Karneios

    The same natural water sources which enabled people to settle the island of Thera in the 8th century BC, are still visible today on the hill of Mesa Vouno. An extensive infrastructure for the exploitation of rainwaters was established in the city of Ancient Thera on Mesa Vouno, which is striking for the quality of its construction as well as the inventiveness of its builders. Rainwater followed ...

  • Risk assessment study for water supply network using GIS

    In recent years, contamination of water in water distribution systems (WDS) has been recognized as a major cause of waterborne diseases. Owing to old and deteriorated pipes, and the presence of pollution sources in contact with the supply line, water boards often decide to replace the network in the interests of public health. This being a cost-intensive and time-consuming programme, decision ...
