The Impact

Research in urban water management has experienced a transition from traditional model applications to modelling water cycles as an integrated part of urban areas. This includes the interlinking of models of many research areas (e.g. urban development, socio-economy, urban water management). The integration and simulation is realized in newly developed frameworks (e.g. DynaMind and OpenMI) and often assumes a high knowledge in programming. This work presents a Web based urban water management modelling platform which simplifies the setup and usage of complex integrated models. The platform is demonstrated with a small application example on a case study within the Alpine region. The used model is a DynaMind model benchmarking the impact of newly connected catchments on the flooding behaviour of an existing combined sewer system. As a result the workflow of the user within a Web browser is demonstrated and benchmark results are shown. The presented platform hides implementation specific aspects behind Web services based technologies such that the user can focus on his main aim, which is urban water management modelling and benchmarking. Moreover, this platform offers a centralized data management, automatic software updates and access to high performance computers accessible with desktop computers and mobile devices.

Urban Water Management

Water resources in many urban areas are under enormous stress due to large-scale urban expansion and population explosion. The decision-makers are often faced with the dilemma of either maintaining high economic growth or protecting water resources and the environment. Simple criteria of water supply and drainage do not reflect the requirement of integrated urban water management. The Urban-Water Harmony (UWH) model is based on the concept of harmony and offers a more integrated approach to urban water management. This model calculates four dimensions, namely urban development, urban water services, water–society coordination, and water environment coordination. And the Analytic Hierarchy Process has been used to determine the indices weights. We applied the UWH model to Beijing, China for an 11-year assessment. Our findings show that, despite the severe stress inherent in rapid development and water shortage, the urban water relationship of Beijing is generally evolving in a positive way. The social–economic factors such as the water recycling technologies contribute a lot to this change. The UWH evaluation can provide a reasonable analysis approach to combine various urban and water indices to produce an integrated and comparable evaluation index. This, in turn, enables more effective water management in decision-making processes.

Management Issues

It is now well accepted that there are significant challenges to realising the widespread and self-sustaining implementation of sustainable urban water management. It is argued that these challenges are entrenched within the broader socio-political framework, yet often unsuccessfully addressed within the more narrow scope of improving technical knowledge and design capacity. This hypothesis is investigated through a comparative analysis of three independent research projects investigating different dimensions of the water cycle, including stormwater management in Australia and sanitary waste management and implementation of innovative technologies in the UK. The analysis reveals significant and common socio-political impediments to improved practice. It was evident that the administrative regime, including implementing professionals and institutions, appears to be largely driven by an implicit expectation that there is a technical solution to solve water management issues. This is in contrast to addressing the issues through broader strategies such as political leadership, institutional reform and social change. It is recognised that this technocratic culture is inadvertently underpinned by the need to demonstrate implementation success within short-term political cycles that conflict with both urban renewal and ecological cycles. Addressing this dilemma demands dedicated socio-technical research programs to enable the much needed shift towards a more sustainable regime.

Abstract Economic growth of any nation like India depends on growth of cities. In India 31% of total population exists in urban extent. Smart City mission of India was established with the objective to deliver the basic requirements of the citizens in a sustainable manner. Madurai city located at Peninsular India with 1.4 Million population was taken for this study. The objective is to develop an Integrated Urban Water Management Strategy after analysing all the components of Urban Water Cycle such as rainfall, runoff, groundwater and wastewater. The population forecast for 2021 was done for the Local Planning Area (LPA) of 726.34 km2 and the water demand was calculated as 109 Mm3/year. To meet the demand, runoff from the average rainfall was estimated as 393 Mm3/yr using SCS-CN method. The storage capacity in the water bodies to store the Surface water was estimated as 156 Mm3/yr and groundwater recharge potential was estimated as 22 Mm3/yr. The Integrated Urban Water Management strategy developed, shows that there is a huge potential for rainwater storage at the surface level and subsequent recharge through artificial recharge techniques.

Water is increasingly taking center stage when it comes to coping with climate change. Especially in urban areas, negative consequences from heavy rainfall events and prolonged dry periods are rising worldwide. In the past, the various tasks of urban water management were performed by different departments that often did not cooperate with each other (water supply, wastewater disposal, green space irrigation, etc.), as the required water supply was not a question of available water volumes. This is already changing with climate change, in some cases even dramatically. More and more, it is necessary to consider how to distribute available water resources in urban areas, especially during dry periods, since wastewater treatment is also becoming more complex and costly. In the future, urban water management will examine water use in terms of its various objectives, and will need to provide alternative water resources for these different purposes (groundwater, river water, storm water, treated wastewater, etc.). The necessary technological interconnection requires intelligent digital systems. Furthermore, the water industry must also play its role in global CO2 reduction and make its procedural treatment processes more efficient; this will also only succeed with adequate digital systems. Although digitization has experienced an enormous surge in development over the last five years and numerous solutions are available to address the challenges described previously, there is still a large gap between the scope of offerings and their implementation. Researchers at Hof University of Applied Sciences have investigated the reasons for this imbalance as part of WaterExe4.0, the first meta-study on digitization in the German-speaking water industry, funded by the German Federal Ministry of Education and Research. Only 11% of roughly 700 identified products, projects and studies relate to real applications. For example, the surveyed experts of the water sector stated that everyday problems are considered too little or hardly at all in new solutions, which greatly overburdens users. Furthermore, they see no adequate possibility for a systematic analysis of new ideas to identify significant obstacles and to find the best way to start and implement a digitization project. The results from four methodologically different sub-surveys (literature and market research, survey, expert interviews and workshops) provide a reliable overview of the current situation in the German-speaking water industry and its expectations for the future. The results are also transferable to other countries.

Integrated Urban Water Management (IUWM) seeks to extend Water Sensitive Urban Design to a total water cycle approach that includes reuse of wastewaters. This paper investigates the appropriateness of environmental technologies for application at a cluster scale in IUWM. Many environmental technologies are economically or physically unsuited to use on a municipal or unit scale. Cluster scale is a middle ground that will allow such environmental technologies to achieve full potential. The concept of cluster scale and the application of environmental technologies at this scale are discussed along with some examples of suitable technologies.

Integrated Urban Water Management (IUWM) has emerged in the past two decades as a promising approach to the application of Integrated Water Resources Management (IWRM) principles at the city-level. IUWM is expected to contribute to the achievement of multiple policy objectives, often including increased water security. This paper uses a case-based approach to study the impact of IUWM on water security, focusing on the influence of the level of institutionalization of IUWM within water governance at the city-level. Process tracing is applied to the cases of Singapore and Hong Kong, in which IUWM has been adopted but implementation and outcomes have diverged. We find that the depth of institutionalization, a difference between the two cases identified at the outset, has contributed to the achievement of better water security outcomes in Singapore as it has facilitated the development and implementation of a more far-reaching strategy. A supportive governance framework appears to amplify the impact of IUWM on progress towards water security and other policy targets.

Urban Water Cycle

A simple model for the urban water cycle is presented, based on mass balances for water and phosphorus. This model is used for the evaluation of the sustainability rate of the urban water cycle. This type of model is to be used in an early stage of town planning, to compare several possible measures. In general, contributing to achieving a more sustainable urban water management. A sensitivity analysis was performed to rank the management options and additional measures to their contribution to the sustainability rate of the urban water cycle. A module for the calculation of cost was linked to the model, revealing the relation between cost and the sustainability rate for a wide range of scenarios. The results show that an improved separated sewer system and the use of a local ground water source have the biggest impact on the sustainability rate. A slightly positive correlation between investment cost and the sustainability rate was found as well.

The Impact

The management of urban groundwater resources is directly linked to urban water supply and drainage concepts. A proper integration of groundwater into urban water management plans is recommended for long-term planning. The paper describes the development of a new modelling suite which addresses the urban water and solute balance in a holistic way. Special focus has been placed on the assessment of the impact of sewer leakage on groundwater in four case study cities. Tools for the prediction of sewer leakage including the assessment of uncertainties are now available. Field investigations in four European case study cities were able to trace the influence of sewer leakage on urban groundwater using microbiological indicators and pharmaceutical residues.
