AWWA WQTC65983

The objective of this study was the development of a technological model describing the effects of different reservoir management strategies on reservoir water quality and quantity, flood retention capacity, the ecological state of the underflow and drinking water treatment. Users of this decision support tool should be able to predict certain states of reservoir water quality and quantity and the underflow's ecological quality as well as their effects on drinking water treatment. This technological model should offer the possibility to find optimal reservoir management strategies for current or prospective incidents using definite target values and limits as input data. The secondary focus of this study was aimed at the description of the impact of varying raw water qualities on drinking water treatment and supply. Water suppliers should use this tool to determine the optimal reaction to changing raw water conditions (e. g. during extreme rain events or droughts, because of modified management strategies or climate change) to guarantee a secure and sustainable water supply. The objective was to make separate predictions of treatment capacity and costs of different treatment technologies for various possible raw water qualities. Includes 8 references, table, figures.
