Benchmarkingmodell för dricksvattenförsörjning i Sverige

Other conference contribution, 2012

The Swedish Water & Wastewater Association has initiated a benchmarking project to assess the quality and quantity, safety and efficiency of drinking water systems in Sweden. An important part of the project is to develop a benchmarking model which provides a useful tool for the municipalities to evaluate the status of their drinking water systems in respect to a safe drinking water quality and quantity. The increased focus on a safe drinking water, in terms of microbiological contaminants, originates from recent outbreaks of waterborne diseases in Östersund and Skellefteå in Sweden. The derived benchmarking model presented in this paper evaluates the safety of the water by a few carefully selected parameters. The model will apply to both small and large drinking water systems and will provide a useful tool for comparison of drinking water systems within Sweden to encourage for a continued improvement of the systems. In addition, the model provides a straightforward and transparent tool for the municipalities to communicate the status of the drinking water systems to the public.
