Abstract
Trinkwasser muss als unverzichtbares Lebensmittel zunächst den gesetzlichen Vorgaben und Verordnungen entsprechen, so dass sein Genuss mit Sicherheit keine Gefährdungen für die Gesundheit bewirkt. Bei Rohwasser genügend hoher Qualität und Verfügbarkeit können weitere Kriterien - auch emotionaler Art - für die Beurteilung des daraus gewonnenen Trinkwassers herangezogen werden, wie etwa "frisch", "ansprechend" oder eben auch "gut". Außer diesen Kriterien wird der Dreiklang aus Qualität, Verfügbarkeit und Zugänglichkeit entscheidend für die Versorgung einer weiter wachsenden Erdbevölkerung mit dem Lebensmittel Trinkwasser. Dem geht diese Broschüre nach, durch die Zusammenführung verschiedener Sichten und Formulierungen zur Qualität guten Trinkwassers.

 

The current rationale, range and significance of Integrated Water Resources Management (IWRM) are subject to increasing dimensionality, such as systemic conflicts between water users, increasing regulatory influences, and the growing energy requirements for providing the appropriate water resources. The competition between urban and agricultural consumers for water is dealt with as are regulatory, technological and socio-economic aspects of IWRM. The conference proceedings of IWRM Karlsruhe 2012 impart knowledge and relate practical experience in three key areas of IWRM:
1. Challenges for Future Cities and Efficient Agricultural Production
Satisfying the growing demand for fresh water for a growing population as well as for agriculture bears the risk of aggravating the conflict between economic and ecological needs. Providing a reliable and secure supply of water for our future cities requires appropriate technical infrastructure systems coupled with environmentally optimized management. In this context it is essential to have greater awareness of the relationship of water and energy and of the overall water usage including the re-use of water
2. Competing Water Uses
Water must be shared between domestic/municipal, industrial, agricultural, and hydropower users as well as between regions. This competition is intensified by the vulnerability of supply and sanitation systems to increasing climate extremes and to terrorism.
3. Regulatory and Policy Framework
Using water is associated with a great number of externalities. For this reason a proper legislative and regulatory framework is prerequisite for proper management of the water supply, sewerage and storm-water services as well as water usage, all of which are essential for public health, economic development and environmental protection.
