Project description
The topic "Water 4.0" describes the increasing complexity of the requirements addressed in water management and the development of integrated solution approaches to handle them. In Germany, the term Water 4.0 refers specifically to digitalization with its many possible applications in water management. The focus of the Federal Environment Agency's research project is water protection and environmental policy perspectives in the context of Water 4.0.
It examines how Water 4.0 can contribute to the goals of water and environmental protection and sustainability. In doing so, it addresses questions such as how to safeguard services of general interest under changing conditions (e.g., climate change) and to what extent, for example, the networking of databases can help with this challenge.
The project serves as a detailed inventory, including the presentation of current developments, problems, and challenges in the field of digitalization of water and wastewater management. The results of this inventory will be presented for discussion at a status workshop, which will foster exchanges of expertise and develop shared understandings regarding the various problems and challenges associated with "Water 4.0". Based on this, conclusions and recommendations for action will be derived from a water and environmental protection policy perspective, and opportunities for establishing a "Water 4.0" network will be identified.

K+S Kali and Salz GmbH operates the Werra and Neuhof-Ellers plants in the Hessian-Thuringian potash region, where approximately 23 million tons of crude salt are extracted annually. Salt extraction and processing, as well as the stockpiling of waste materials, produces saline wastewater, which is either discharged directly into the Werra or sunk underground.
In the 2009 update of the management plan for the Weser catchment area, the concept for the future environmentally compatible disposal of wastewater was defined in the context of the EU Water Framework Directive (WFD 2000). This Directive requires, among other things, an examination of the efficiency of the proposed measures and an understanding of the proportionality and the reasonableness of the measure options.
The FGG Werra/Weser and the Round Table "Water Protection Werra/Weser and Potash Production" discussed options for measures to deal with the saline wastewater.
These included a reduction in the discharge of salt and the construction of long-distance pipelines to the Upper Weser and the North Sea.
In the expert report, measure options were evaluated using an eco-efficiency analysis, thus preparing the proportionality assessment by the State of Hesse.
The report was prepared in cooperation with Dr.-Ing. Bernhard Michel from COOPERATIVE Infra struktur und Umwelt Reinheim.
Analysis and evaluation of the sustainability and eco-efficiency of small wastewater treatment plants with a derivation of product improvements
Processing period: Oktober 2014
Project participants at the professorship: Sabine Lautenschläger
Research project, funded by the German Federal Environmental Foundation (DBU)

www.wifa.uni-leipzig.de/iirm/iirm.html
Objective and reason
Although fully biological small wastewater treatment plants (WWTPs) are recognized as a durable solution for wastewater treatment and are already used on a large scale, information concerning the ecological sustainability of the production and operation of these WWTPs is not yet available. Due to the existence of many plant types and a lack of comprehensible decision criteria, interested parties, users, and local decision-makers are often helpless in the face of market diversity. With the analysis and evaluation of the eco-efficiency of MSWTPs, the relation between environmental impact and cost, a parameter is available in principle that is very well suited to provide decisive information for a practical system selection and, in addition, to show plant manufacturers information and approaches for product improvement.
Project content
Within the scope of the project, a methodological approach for determining the eco-efficiency of decentralized wastewater treatment plants is developed, which will facilitate the ecological-economical evaluation and optimization of products for plant manufacturers and suppliers. The entire life cycle of a product or process is considered, including the extraction of raw materials, manufacturing processes and plant usage, and the disposal of residual materials and components. A detailed information base is developed regarding energy consumption, greenhouse gas emissions, and environmental impacts for the different life cycle phases, process steps, construction methods, material uses and disposal paths, as well as different plant sizes. Based on this, identified environmental impacts are aggregated in a suitable form. To aggregate these impacts, a standard is defined within the scope of the project that is as close to practice as possible, enabling comparisons across different types of plants.
The project is accompanied by a project advisory board. Project duration: 09/13 to 09/14

Project description
The concept of sustainability has shaped political debate for more than three decades. In view of global socio-economic and ecological developments and accompanying increases in environmental pollution and resource scarcity, it is to be expected that debate concerning the goals, design and effects of a sustainable approach to these global change processes will become more concrete in the near future. Sustainability should reconcile the three goals of environmental protection, economic prosperity, and distributive justice. The weighting of these goals and the choice of instruments to achieve them are left to the political decision-maker. However, economic science oriented towards economic efficiency can make an important contribution to economic policy debates on sustainability and thus facilitate a rational societal discussion on sustainable development.
The project aims to contribute to this debate by examining the coherence of sustainability goals and economic instruments in the regional context of global change processes. Among other factors, this includes generating a better understanding of the future boundary conditions for local and regional economic development.
The modules focus on global climate change as one of the most urgent sustainability problems. The topics are addressed by applying theoretical and empirical approaches on a solid methodological basis: including methods for modeling ecological-economic interactions and those that engage empirical economic research. By considering the distributional effects of climate policy, the project will also contribute to the social dimension of sustainability in Saxony and its relationship to the ecological and economic dimensions.
Due to the close interdisciplinary cooperation of the project partners, the interplay of technical planning, regional development and economic-scientific aspects, in particular, are recorded in this project.
Here, the project significantly strengthens the performance of the two Saxon universities, the University of Leipzig and the Leipzig University of Applied Sciences (HTWK), as well as the Leipzig science region.

Project description
The joint research project of the Helmholtz Centre for Environmental Research (UFZ) and the IIRM builds on the report "Further Development of Wastewater Levy and Water Use Charges into a Comprehensive Water Use Levy", which was also prepared for the Federal Environment Agency. The new project aims to develop concrete proposals for strengthening (making more effective) the wastewater levy based on the theoretical findings of the aforementioned report.
For this purpose, different design options that consider the conflicting objectives of "steering intensity, practicability, revenue, economic justifiability" are to be systematically prepared and backed up with criteria to derive appropriate recommendations. The developed proposals serve to prepare for the amendment of the Wastewater Levy Act (AbwAG).
Mapping of cost influences of different framework conditions in wastewater disposal with special consideration of the structures of the Emschergenossenschaft

Client: Emschergenossenschaft/Lippeverband
Project description
Wastewater disposal is a basic infrastructure service whose construction and operation regularly involve,
and are regularly associated with, high investment volumes and costs. These costs are either passed on directly to the consumer by charging fees or, as in the case of the Emschergenossenschaft, refinanced by cooperative contributions from member municipalities and then indirectly passed on to the consumer via municipal fees. Varying local costs and pricing differences between different water service providers repeatedly lead to the need for explanations vis-à-vis state institutions and the public. With an increasing focus on the costs of water management services, there is a demand for public authorities to engage in dialogue with the public and to transparently communicate the interdependencies between services provided and their resulting costs.
The project will develop basic principles that will serve as an argumentation aid for the Emschergenossenschaft vis-à-vis regulatory decision-makers and potential regulators. The argumentation logic is to make justified differences in costs and the pricing structures of different wastewater disposal companies understandable. In terms of methodology, the project is based on the experience of companies affected by antitrust proceedings in the water supply sector (cf. Holländer et al., 2009).

Sub-project: Techno-economic development scenarios and model-based analyses
Project description
Based on the situation that traditional central infrastructure systems are under pressure to change due to rising societal expectations regarding resource efficiency and economic viability, and as a result of global and regional change processes (i.e., climate, demographics, consumption patterns), sustainable system solutions are being sought. As a result of uncertainties connected to future developments, it is necessary to align technical-economic system interests with sustainability interests in the long term. This objective will be investigated from a technical-economic, institutional-economic, and legal perspective within this interdisciplinary joint project.
The IIRM sub-project "Techno-economic development scenarios and model-based analyses" compares possible target points for approaching sustainable infrastructure development as well as suitable development scenarios to achieve the targets. With the help of an agent-based model, the steering influence of institutions and framework conditions for development paths will be analyzed in an exemplary way.

Project description
This report follows the work of two previous reports for the Association of Municipal Enterprises (VKU), which identified factors affecting the cost structure of drinking water suppliers. This report focuses on wastewater disposal, whose task and process structure is in part very different from that of drinking water supply. The report aims to identify and analyze the impact of region-specific features of Germany's wastewater industry in relation to wastewater pricing. In doing so, it is important to consider the effects of external framework conditions on the cost structure (cost incidence) and their distribution over a specific pricing model. The results of the report serve to support professional argumentation of wastewater charges towards municipal committees, citizens and the local public

Project description
A political goal in Saxony is to guarantee a comprehensive wastewater disposal system that does justice to the protection of water and resources and at the same time remains affordable. However, responsible authorities, especially in rural areas, face significant challenges in this regard. An example of this is the wastewater association AZV Espenhain, which serves about 36,700 inhabitants in the southern region of Leipzig. In retrospect and according to forecasts, its development is characterized by a declining population and a reduced wastewater volume. At the district level, however, extremely divergent lines of development can be seen. In addition to stable districts, there are also peripheral settlements with unpredictable development prospects. Furthermore, the vastness of the disposal area and the lack of receiving waters and seepage possibilities in some areas make proper
