Urban Water Cycle

The traditional approach to urban water management is primarily based on a supply-oriented approach, where water follows a one-way path from supply to a single use, treatment and then discharged to the environment. The wide acknowledgement of the need to shift towards more sustainable practices has led to the recognition that demand is multi-faceted; delivered supply should correspond to the varying characteristics of users, taking into account their actual needs in terms of quantity, quality and level of reliability. Such an approach can entail the application of reuse and reclamation methods, which allow for the multiple use of water to meet higher to lower quality needs. Integrated urban water cycle modelling can be a powerful tool in estimating the potential for the application of such options, as it considers issues related to water supply, wastewater production and stormwater runoff in a holistic framework. This paper presents preliminary results from the application of an integrated urban water balance model, Aquacycle, in the Greater Athens Area. The Aquacycle model accounts for water pathways by simulating two subsystems of the urban water cycle (the rainfall-run-off network and the water supplywastewater network), and the interactions between them. The software package can also be used for evaluating alternative stormwater and wastewater reuse schemes. In this paper, Aquacycle was used for simulating water use, wastewater production and stormwater drainage in the Greater Athens Area. For applying the model, the region was divided into smaller – cluster – scales, according to specific structural characteristics. Then, the model was calibrated and validated against measured data, so that model outputs can account for the overall complexity of the Athens urban environment. Finally, three alternative scenarios, comprising the application of on-site recycling and reuse technologies were simulated and evaluated on the basis of three sustainability indicators (i.e. reduction of imported freshwater, wastewater and stormwater discharge).

Urban Water Cycle

Water cycle analysis was performed for Gunja basin located in metropolitan Seoul using Aquacycle model in order to assess the problems of urban water cycle. From the water cycle analysis of Gunja basin, it was found that 75% of total rainfall occurred in the form of surface runoff, and groundwater recharge only accounted for about 7%. This suggests serious distortion of water cycle which can be attributed to urbanization. Feasibility analysis of reuse scenarios such as rainwater use and wastewater reuse was then performed to examine their influences on improving the water cycle. From the analysis of water reuse options, it was shown that imported water supply savings of 13% can be achieved through rainwater use, and water supply savings of 31% through wastewater reuse.

Urban Water Cycle

The character of urban water cycle does not comply with the principles of sustainability. The task of restructuring the urban water cycle is to create a system which is close to a natural. The approached method for this research was to develop and demonstrate a new comprehensive system in two cities of Germany (Dortmund and Zwickau). Standardized types of settlement structure were developed in order to obtain transferable results and to portray the total spectrum of urban planning situations.

Urban Water Cycle

This paper proposes the use of directional distance functions and Data Envelopment Analysis techniques to assess technical efficiency in the provision of the different stages of the urban water cycle in Andalusia, a Southern European region. Evaluating performance in the management of specific stages of the urban water cycle provides utility managers and regulating authorities with relevant information that may not be detected by more conventional approaches based on assessing performance at utility level. We find that Andalusian water and sewage utilities could achieve significant increases in the volume of water delivered without diminishing the output of their other services and using the same quantities of inputs. Potential increases are also important for the volume of sewage collected, thus entailing significant environmental benefits in a territory where water scarcity has seen the efficient management of this natural resource become a pressing obligation.
