Veröffentlichung Indications of recent warm and dry summers' impact on private wells for drinking-water supply in Germany: a review of press articles(2022) Görnt, Annika; Rickert, Bettina; Vogelsang, L.; Ruhl, Aki SebastianClimatic changes lead to seasonal droughts with declining groundwater levels, and - especially in rural regions - private wells in the upper aquifer might fall dry. However, only limited information and no systematic administrative reporting of the extent are available for Germany yet. Therefore, a systematic analysis of newspaper articles as a promising source of information was conducted for the extraordinarily hot summers of 2018, 2019 and 2020. The results of the database searches were analysed with respect to frequency and local and regional hotspots, relations to climatic data, extent of the reported dry-fallings and emergency water supply. The analysis indicates hotspots particularly for the federal states of Saxony, where a subsidy programme for connecting to the public water supply was reissued in 2019, for Bavaria and North Rhine-Westphalia. Emergency supply was realised through various approaches. It was partly required until the winter months and did not always have drinking-water quality. As private wells are particularly vulnerable to the effects of climate change, their operators should be involved as a stakeholder group in future discussions about allocating water resources to increasingly competing uses in periods of scarcity. © 2022 The AuthorsVeröffentlichung Implementation and evaluation of the water safety plan approach for buildings(2019) Rapp, Thomas; Rickert, Bettina; Schmidt, Isabelle; Schmoll, OliverThe World Health Organization promotes water safety plans (WSPs) - a risk-based management approach - for premise plumbing systems in buildings to prevent deterioration of drinking-water quality. Experience with the implementation of WSPs in buildings were gathered within a pilot project in Germany. The project included an evaluation of the feasibility and advantages of WSPs by all stakeholders who share responsibility in drinking-water safety. While the feasibility of the concept was demonstrated for all buildings, benefits reported by building operators varied. The more technical standards were complied with before implementing WSP, the less pronounced were the resulting improvements. In most cases, WSPs yielded an increased system knowledge and awareness for drinking-water quality issues. WSPs also led to improved operation of the premise plumbing system and provided benefits for surveillance authorities. A survey among the European Network of Drinking-Water Regulators on the existing legal framework regarding drinking-water safety in buildings exhibited that countries are aware of the need to manage risks in buildings' installations, but experience with WSP is rare. Based on the successful implementation and the positive effects of WSPs on drinking-water quality, we recommend the establishment of legal frameworks that require WSPs for priority buildings whilst accounting for differing conditions in buildings and countries.

Results of a survey conducted under the Protocol on Water and Health(World Health Organization. Regional Office for Europe, 2016) Samwel, Margriet; Rickert, Bettina; Shinee, Enkhtsetseg; Kozisek, Frantisek; Schmoll, Oliver; World Health Organization. Regional Office for EuropeSmall-scale systems are an important component of water supplies in the WHO European Region. To improve the evidence base on small-scale water supplies and to gain a better overview of the status quo throughout the Region, the WHO Regional Office for Europe and the United Nations Economic Commission for Europe made a survey requesting country-specific information in 2012-2013 under the Protocol on Water and Health to the 1992 Convention on the Protection and Use of Transboundary Watercourses and International Lakes. The survey had a high response rate (81%), and this analysis of the results includes responses from 43 of the 53 countries in the WHO European Region.
This report summarizes the findings of the survey, which showed that about 23% of the population of the Region receive their drinking-water from small-scale systems. The results reveal that comprehensive information on small-scale water supplies is typically not readily available at the national level across the Region, which hampers systematic assessment of the prevailing conditions. Establishing national registers of small-scale water supplies and routine data collection mechanisms would improve the evidence base and thus support the prioritization of improvements. The findings of the assessment are intended to inform policy-making and the formulation of intervention strategies and to help identify further action under the Protocol.

This happened in response to increasing insight into impacts of climate on drinking-water and required adaptation to anticipated climate change. Literature was reviewed for published guidance and case examples, documenting how to consider climate in water safety planning to support future uptake. Climate-resilient water safety plans were piloted within a project in the water supplies of Addis Ababa and Adama, Ethiopia. Case examples have been published in four of six WHO regions with a focus on urban supplies. Integration of climate aspects focused mostly on the steps of establishing the team, system description, hazard analysis and risk assessment, improvement planning and development of management procedures. While the traditional framework focuses on drinking-water quality, considering climate change augments aspects of water quantity. Therefore, other factors affecting water quantity such as population development and demand of other sectors need to be considered as well. Local climate information and tools should be employed as a significant success factor for future uptake. Such information should be incorporated as it becomes available, and may - depending on the setting - be incrementally integrated into existing water safety plans or used to develop new ones. © 2019 The Authors. Published by Elsevier GmbH.Veröffentlichung Success factors for water safety plan implementation in small drinking water supplies in low- and middle-income countries(2020) Herschan, Jo; Mkandawire, Theresa; Rickert, BettinaThe proper operation of a water supply system (WSS) requires constant investment. The priority is to provide residents with high quality potable water, in the required quantity and pressure, in accordance with the applicable regulations. The paper presents an assessment of the potential inherent operational risk of a WSS in support of the risk-based investment management process. It is of high importance to invest in the operational safety as it concerns both producers and consumers. The investment engenders additional costs that should partially be supported by the consumers. Thus, the paper presents a methodology to analyse consumers' readiness to accept water supply services' additional costs. The proposed methods may underpin a comprehensive program for risk-based investment management and operational decision-making. The case study and the approach in this article concern one particular regional WSS, based on information collected from water consumers. The assessment suggests a willingness to tolerate additional costs in view of enhancing the performance of the water supply services. © 2020 by the authors.Veröffentlichung Status of small-scale water supplies in the WHO European Region.

Quelle: http://www.euro.who.intVeröffentlichung Capacity building and training approaches for water safety plans: A comprehensive literature review(2019) Ferrero, Giuliana; Setty, Karen; Rickert, BettinaThe World Health Organization has recommended Water Safety Plans (WSPs), a holistic risk assessment and risk management approach, for drinking-water suppliers across low-, middle- and high-income countries, since publishing its 2004 Guidelines for Drinking-Water Quality. While rapid WSP adoption has occurred, capacity is still catching up to implementation needs. Many countries and regions lack case examples, legal requirements, and training resources for WSPs, corresponding to widespread capacity shortfall in the water supply sector. We undertook a comprehensive review of the literature on capacity building and training for WSPs, with the goal of providing recommendations for multiple stakeholder groups at the scales of individual utilities, national governments, and intermediate units of governance. We propose a WSP training taxonomy and discuss it in relation to the stages of learning (introduction, practice, and reinforcement); describe the importance of customizing training to the target group, local language and circumstances; highlight the relevance of auditing for evaluating change over time; and call for robust methods to monitor WSP capacity development. © 2019 World Health Organization. Published by ElsevierVeröffentlichung Comparing the german enabling environment for nationwide water safety plan implementation with international experiences: Are we still thinking big or already scaling up?(2020) Schmiege, Dennis; Evers, Mariele; Rickert, Bettina; Zügner, VerenaEnsuring safe drinking-water is the target of the Water Safety Plan (WSP) approach, which has been successfully applied to a large number of water supply systems around the world. Effective country-wide scaling up of WSP implementation requires an enabling environment at the policy level. By utilizing a multi-step mixed methods approach, this study summarizes international experience with WSP implementation and scaling-up efforts following the 8 steps of the WSP road map published by WHO and IWA for an enabling environment, shows what steps Germany has in place, and compares this with published international experience to inspire further policy action. Contrasting the international experience to the German situation revealed several overlaps but also profound differences, which, in turn, offer opportunities for mutual learning. Most experience in Germany and internationally is documented for the earlier steps of the WSP road map. Information particularly on developing a national strategy, securing financial instruments, activities to support continual implementation of WSPs and on review of the overall WSP experiences and sharing lessons learned appears to be scarce, while the importance of training, collaboration and alliances, and the value of a regulatory push are often stressed. In Germany, stakeholder engagement, guidance documents and workshop materials have been of vital importance. Information that could particularly inform further action in Germany mostly relate to considering a national WSP strategy, and how to shape an approach for external quality assurance of WSPs.Veröffentlichung Gesundes Trinkwasser aus eigenen Brunnen und Quellen(2013) Rickert, Bettina; Schmoll, OliverVeröffentlichung Country small-scale water supplies and sanitation under the protocol on water and health(2018) Rickert, Bettina
