Flexibility Options

Urban drainage systems are influenced by several future drivers, which affect the performance as well as the costs of the systems. The review of the different future drivers for urban drainage systems illustrates, that no sufficient future predictions for the long operational life span of the systems are possible. To deal with these future uncertainties flexible urban drainage systems are required. The paper combines different analysis of the authors, to ascertain first insights about flexible urban drainage systems. In the present technical literature profound insights about definition, measurement and generation of flexibility for urban drainage systems are missing. Hence the theory of flexibility from other disciplines is transferred to the field of urban drainage. A theoretical basis for flexible urban drainage systems is presented. The thematic priority is the generation of flexibility options for urban drainage systems. On the one hand in an analysis it is verified, that decentralised urban drainage systems offer a higher flexibility than conventional drainage systems. On the other hand a generic framework for the planning and measurement of flexibility options of urban drainage systems in individual cases is presented. The paper illustrates, that a transfer of the general theoretical background of flexibility to the field of urban drainage systems is possible. A definition of flexibility, metrics for the measurement of flexibility and a framework for the identification of flexibility options are substantiated for urban drainage systems. Therewith a basis for the implementation of flexible urban drainage systems is offered.

ResumenEste artículo es una síntesis del proyecto de investigación realizado en la Universidad de Sevilla para diseñar un modelo de análisis que permita la comprobación de la viabilidad técnica y socioeconómica de los proyectos de rehabilitación hidrológica de barrios urbanos, mediante la construcción de infraestructuras de drenaje sostenibles. El modelo propuesto presenta novedades significativas con respecto a los empleados tradicionalmente en los sistemas urbanos de drenaje sostenible. En primer lugar, se parte de la base de la realización de análisis previos que permitan comprobar la posibilidad de recuperación del agua de lluvia para que, tras sencillos tratamientos para eliminar sus posibles contaminantes, pueda ser usada en labores urbanas del barrio que no requieren agua de calidad. Además, al plantearse como un proyecto cuyo objetivo es “la rehabilitación hidrológica” de un barrio urbano habitado, se contempla medidas clave para conseguir la interacción con los agentes sociales que intervendrán en la gestión local del ciclo del agua, incluyendo medidas sociales y educativas relacionadas con el uso del agua. La finalidad del modelo es aportar los suficientes datos, tanto relacionados con las características del lugar como con la calidad del agua, para poder diseñar unos Sistemas Urbanos de Drenaje Sostenible que sean adecuados.AbstractThis paper summarizes a research project conducted in the University of Seville, in order to design an analysis model that allows the assessment of technical and socio-economic viability of hydrological rehabilitation projects in urban neighbourhoods, through the construction of sustainable drainage infrastructures. The model proposed presents significant developments when compared with the ones traditionally used in sustainable urban drainage systems. On the one hand, the possibility of recovering rainwater with simple treatments, eliminating potential contaminants, has been verified previously, testing water for urban purposes with no quality requirements. Moreover, since the main objective of this project is the “hydrological rehabilitation” of an inhabited neighbourhood, the interaction with social agents is a key factor that must be considered for a more appropriate local management of the water cycle, thus social and educational measurements related to the use of water have been included. The aim of this model is to present sufficient data, both referred to the water quality and hydrological conditions of the neighborhood, in order to design adequate Sustainable Drainage Urban Systems.

Definition Of

The implementation of sustainable urban drainage systems (SUDS) is increasing due to their advantages, which transcend runoff control. As a result, it is important to find the appropriate SUDS locations to maximize the benefits for the watershed. This study develops a multiscale methodology for consolidated urban areas that allows the analysis of environmental, social, and economic aspects of SUDS implementation according to multiple objectives (i.e., runoff management, water quality improvements, and amenity generation). This methodology includes three scales: (a) citywide, (b) local, and (c) microscale. The citywide scale involves the definition of objectives through workshops with the participation of the main stakeholders, and the development of spatial analyses to identify (1) priority urban drainage sub-catchments: areas that need intervention, and (2) strategic urban drainage sub-catchments: zones with the opportunity to integrate SUDS due the presence of natural elements or future urban redevelopment plans. At a local scale, prospective areas are analyzed to establish the potential of SUDS implementation. Microscale comprises the use of the results from the previous scales to identify the best SUDS placement. In the latter scale, the SUDS types and treatment trains are selected. The methodology was applied to the city of Bogotá (Colombia) with a population of nearly seven million inhabitants living in an area of approximately 400 km2. Results include: (a) The identification of priority urban drainage sub-catchments, where the implementation of SUDS could bring greater benefits; (b) the determination of strategic urban drainage sub-catchments considering Bogotá’s future urban redevelopment plans, and green and blue-green corridors; and (c) the evaluation of SUDS suitability for public and private areas. We found that the most suitable SUDS types for public areas in Bogotá are tree boxes, cisterns, bioretention zones, green swales, extended dry detention basins, and infiltration trenches, while for private residential areas they are rain barrels, tree boxes, green roofs, and green swales.

The European research project in the EUREKA framework, RisUrSim is presented with its overall objective to develop an integrated planning tool to allow cost effective management for urban drainage systems. The project consortium consisted of industrial mathematics and water engineering research institutes, municipal drainage works as well as an insurance company. The paper relates to the regulatory background of European Standard EN 752 and the need of a more detailed methodology to simulate urban flooding. The analysis of urban flooding caused by surcharged sewers in urban drainage systems leads to the necessity of a dual drainage modeling. A detailed dual drainage simulation model is described based upon hydraulic flow routing procedures for surface flow and pipe flow. Special consideration is given to the interaction between surface and sewer flow during surcharge conditions in order to most accurately compute water levels above ground as a basis for further assessments of possible damage costs. The model application is presented for a small case study in terms of data needs, model verification and first simulation results.
