    Decision-support for a sustainable regional water supply management2016In: The 10th Nordic Drinking Water Conference, 2016Conference paper (Other academic)
    Abstract [en]

    The provision of a safe drinking water is of primary importance in society and a prerequisite for public health and economic development. In order to secure a long-term, safe and reliable supply of drinking water, and to ensure a comprehensive and integrated water planning, the development of regional water supply plans is increasingly requested in Sweden. To implement the plans, the water utilities, regional planners and politicians need to make several complex decisions and prioritize between multifaceted strategic measures. There are, however, very few decision support tools adapted for water supply management on the regional level to aid the decision makers. In order to achieve a sustainable drinking water supply, socio-economic effects need to be carefully considered. Hence, this study focuses on the development of a decision support framework for assessing socioeconomic effects of strategic decisions and alternative water supply measures by adapting costbenefit analysis (CBA) and economic valuation techniques to a long-term and regional perspective. The Gothenburg region, with its newly presented regional water supply plan, serves as a case study for which five alternative measures are evaluated: (1) centralization of water supply production; (2) centralization of water supply organization; (3) shift of the main raw water intake from the river Göta älv, a raw water source exposed to a high contamination risk, to the cleaner water of lake Vänern; (4) maximization of groundwater usage; and (5) increased number of raw water resources. The effects of each alternative are identified through literature reviews, stakeholder workshops and dialogues with experts and policy makers. To assess the non-market costs and benefits of the alternative strategies, the benefit transfer method is used for adapting estimates from national and international valuation studies to the Gothenburg region. The monetized costs and benefits are then used to set up a longrun CBA to identify the best strategy from a social welfare perspective. The net present values (NPVs) of the alternative measures are estimated for three different discount rates (constant rates of 1.4 % and 3.5 % as well as a declining discount rate) and two different time periods (ranging to 2050 and 2100). Uncertainties concerning the NPVs are analyzed by means of statistical simulation (Monte Carlo), accounting for uncertainties in input data. For the Gothenburg region, the results show the effect of the various strategies and give a direct guidance on which measures are most favorable from a cost-benefit perspective. The case study results are then used to design a general decision support framework that allows for non-market valuations and economic and ecological tradeoffs under uncertainty, a novelty on the regional scale. In conclusion, it is expected that the results of this study will provide decision makers and regional planners with a framework of tools to improve their ability to make well-informed decisions and to ensure the society a safe and reliable water supply for generations to come.

    Sustainability assessments of regional water supply interventions – Combining cost-benefit and multi-criteria decision analyses2018In: Journal of Environmental Management, ISSN 0301-4797, E-ISSN 1095-8630, Vol. 225, p. 313-324Article in journal (Refereed)
    Abstract [en]

    To cope with present and future challenges, a growing number of water utilities in Sweden, Europe and elsewhere initiate various forms of inter-municipal cooperations creating a new regional level of drinking water governance. In order to reach viable decisions of alternative ways forward, there is an international consensus that sustainability needs to be addressed in water supply planning, design and decision-making. There are, however, few decision aids focusing on assessing the sustainability of inter-municipal cooperations and the inter-municipal policies and interventions that regional decision-makers are faced with. This paper presents a decision support model based on a combination of cost-benefit analysis and multi-criteria decision analysis for assessing the sustainability of regional water supply interventions, including formations of inter-municipal cooperations. The proposed decision support model integrates quantitative and semi-quantitative information on sustainability criteria. It provides a novel way of presenting monetized benefits and costs, capturing utilitarian aspects of alternative interventions, with non-monetized social and environmental effects, capturing aspects based in the deontological theories of moral ethics. The model is based on a probabilistic approach where uncertainties are defined by statistical probability distributions. A case study is used to exemplify and evaluate model application in decision situations regarding regionalization, (de)centralization, source water quality and redundancy. All evaluated alternatives were expected to contribute to a slightly improved social sustainability, whereas the results were more varying in the economic and environmental domains. A structured and transparent treatment of uncertainties facilitates a better understanding of the results as well as communication between decision-makers, stakeholders and the community.

    Combining cost benefit analysis with multi criteria analysis for sustainability assessment of regional water supply policies2016In: Society For Risk Analysis Annual Meeting 2016, 2016Conference paper (Other academic)
    Abstract [en]

    The provision of safe drinking water is of primary importance in society and a prerequisite for public health and economic development. This provision is however threatened by a variety of risks due to e.g. climate change and societal development. To manage these risks the water utilities are facing complex decision situations. Today, decisions on costly investments are being made with limited knowledge of which choices are the most sustainable. In order to achieve a safe and sustainable water supply, a regional perspective on the environmental, social and economic effects of the decisions is increasingly promoted in Sweden. There are, however, few decision support tools adapted to the regional level. Hence, this study focuses on the development of a decision support framework for assessing the sustainability of risk reducing measures by adapting Cost-Benefit Analysis (CBA) and Multi Criteria Analysis (MCA) to a regional perspective. The Gothenburg region serves as a case study for which five measures are evaluated: (1) centralization of water supply production; (2) centralization of water supply organization; (3) shift of the main raw water source (4) maximization of groundwater usage; and (5) use of additional raw water sources. All measures aim to enhance safety by reducing risks. Uncertainties concerning the net present values are analyzed using statistical simulation (Monte Carlo). The CBA results are complemented with environmental and social effects in an MCA, including criteria such as intrinsic values, equity and health. The case study results are then used to design a decision support framework that allows for non-market valuations and economic and ecological tradeoffs under uncertainty, a novelty on the regional scale. In conclusion, it is expected that the results of this study will provide decision makers with a framework that can improve their ability to make well-informed decisions and ensure the society a safe water supply for generations to come.

    Abstract [en]

    The purpose of this project is to provide support to local municipalities and other stakeholders on how sprinkler installations connected to the water mains should be installed and maintained so that a high fire safety can be obtained without any inconvenience or disturbances to the municipal water supply. The report includes recommendations for how Swedish municipalities can manage applications for sprinkler connections, and how the sprinkler industry can handle the design, installation and maintenance to minimize the risk for drinking water quality problems.Key words:Sprinkler, public water mains, drinking water quality, backflow prevention, sprinkler pumps, capacity test.
