Abstract
Although the availability of safe and clean water from municipal use is severely limited, the demand for it is increasing rapidly in many cities of the world. The continual construction of stormwaterlsewerage systems, water storages and water distribution networks aimed at providing water security with rapid urbanization is no longer a sustainable solution, because of the financial and environmental impacts. Therefore, decentralized water cycle management tools, like Water Sensitive Urban Design (WSUD - the Australian version of sustainable water cycle management) or Low Impact Development (LID - the corresponding strategy in North America) need to be considered to provide sustainable solutions for urban water cycle management. The idea of WSUD or UD focuses on natural water cycle management in the urban landscape. This has resulted in technology designed in such a way that it can capture and temporarily retain stormwater and divert it away from the drainage channel: possible diversion includes recharging of aquifer.
This paradigm shift is an aid to solving the everyday problems of small scale stormwater management-llood control, pollution control and stormwater harvesting. This paper deals with an overview of concept, design approach and technologies of WSUD for sustainable stormwater management in South Australia. Adaptation techniques, barriers of application, fundamental philosophies, components and existing projects of WSUD in the context of South Australia are the major focuses of this paper. The WSUD approach could be equally applicable to developing countries including Bangladesh for minimizing the fiood frequency and improving water quantity and quality.
