Abstract Stormwater harvesting for residential and non-residential reuse is an important and crucial aspect to reduce freshwater demand to address climate change, population growth and urbanisation challenges. It is important that freshwater be conserved as much as possible through capturing rainwater and stormwater and using these resources for fit for purpose end uses such as irrigation of public open parks and residential non-potable end uses. The paper describes a methodology for the planning and design of a stormwater harvesting system for park irrigation. The application of suitable models for storage tank capacity and pipe sizing considering peak flows are described. The application of the approach is demonstrated with a local case study for the benefit of wider water professionals engaged in water-sensitive urban design.

Water sensitive urban design (WSUD), as a typical green stormwater infrastructure (GSI), contains various facilities to decrease the urbanization impacts and enhance the values of amenity, ecosystem, and livability in Australia. Although WSUD has developed over 30 years, existing studies for WSUD performances have sometimes ignored its economic and social benefits, and there is still a lack of an integrated framework to optimize the GSI combinations based on various criteria in a site. This paper aims to utilize “score-rank-select” strategy to comprehensively assess WSUD combination scenarios from functional, economic, social, and environmental aspects, by taking the University of Melbourne (Parkville campus) as a case study. In detail, multi-criteria decision analysis (MCDA) was used for weight determination and scenario comparison. The results showed that scenario 4 with 52% green WSUD facilities had the highest assessment score (0.771) among the five scenarios, while the final score (0.758) of scenario 5 was lower than scenario 4 although its green facility proportion reached 69%. The trade-off relation between the proportion of grey and green WSUD facilities was further demonstrated. Additionally, this paper strongly recommends that the MCDA-based comprehensive assessment framework described here can be generally promoted for the water sector to solve the decision-making problems. The use of such a framework can further promote sustainable development by helping water managers to make informed and inclusive decisions involving a variety of factors.

Alternative Sources

Water sensitive urban developments are designed with integrated urban water management concepts and water sensitive urban design measures. The initiatives that may be included are the substitution of imported drinking water with alternative sources using a fit-for-purpose approach and structural and non-structural measures for the source control of stormwater. A water sensitive approach to urban development can help in achieving sustainability objectives by minimising disturbance to ecological and hydrological processes, and also relieve stress on conventional water systems. Water sensitive urban developments remain novel in comparison with conventional approaches, so the understanding and knowledge of the systems in regards to their planning; design; implementation; operation and maintenance; health impacts and environmental impacts is still developing and thus the mainstream uptake of these approaches faces many challenges. A study has been conducted to understand these challenges through a detailed literature review, investigating a large number of local greenfield and infill developments, and conducting extensive consultation with water professionals. This research has identified the social, economic, political, institutional and technological challenges faced in implementing water sensitive urban design in greenfield and infill developments. The research found in particular that there is the need for long-term monitoring studies of water sensitive urban developments. This monitoring is important to validate the performance of novel approaches implemented and improve associated guidelines, standards, and regulatory and governance frameworks, which can lead to mainstream acceptance of water sensitive urban development approaches. The dissemination of this research will help generate awareness among water professionals, water utilities, developers, planners and regulators of the research challenges to be addressed in order to achieve more mainstream acceptance of water sensitive approaches to urban development. This study is based on existing water sensitive urban developments in Australia, however, the methodology adopted in investigating impediments to the uptake of these developments can be applied globally. It is hoped that insights from this study will benefit water professionals in other countries where there is also a move towards water sensitive urban development.

Improve Water Quality

The ongoing challenge of maintaining and improving the quality of water that leaves urban stormwater systems is often addressed using technical rather than social solutions. The need for investment in often expensive water infrastructure can be reduced through better investing in promoting human behaviors that protect water quality as part of water-sensitive urban design (WSUD) initiatives. Successfully achieving this requires understanding factors that influence adoption of proenvironmental behaviors. We review past studies examining this topic and identify that factors influencing adoption of proenvironmental behaviors relevant to WSUD commonly fall into four domains: proenvironmental values and norms, awareness and knowledge of environmental problems and the actions that can address them, proximity and place-based identity, and life-stage and lifestyle factors. We propose the VAIL (values, awareness, identify, lifestyle) framework, based on these four domains and able to be contextualized to specific water-quality problems and individual communities, to assist in diagnosing factors influencing adoption of proenvironmental behaviors. We demonstrate the applicability of the framework in a case study examining adoption of gardening practices that support water quality in Canberra, Australia. We developed 22 locally relevant VAIL indicators and surveyed 3,334 residents to understand engagement in four water-friendly gardening behaviors that help improve water quality in local lakes. In regression modeling, the indicators explained a significant amount of variance in these behaviors and suggested avenues for supporting greater adoption of these behaviors. Predictor variables across all four VAIL domains were significant, highlighting the importance of a multidomain framework.

Increasingly independent fields of specialization, civil engineering, and urban design find themselves practicing in isolation on the same urban issues. The result surfaces on the relative qualities of public spaces: projects that are functionally successful but spatially poor, and vice versa This is critical in the global south, where infrastructure is prioritized, and politicized, as the key driver of change but often heedless of spatial consequences. The present study explores the dynamics of integration between logics arising from technical and spatial fields, and the planning processes under which such integration is feasible. An urban design/infrastructural project in Argentina, stalled for more than two decades under regulatory policies, was selected as a case study. An overview and background of the adopted planning/design methodologies are followed by a structural/spatial analysis, focusing on type, logistics, and construction on the one hand, and on indicators of successful public spaces on the other: access, uses, comfort and image. Aspects that a priori appeared as inevitable compromises found a common, but the critically logical ground in which urban and structural thinking complemented each other. More than a functional asset, infrastructure presents an opportunity to re-think the future of the built environment as a typology that could be conceived, designed and evaluated, on the same terms as successful public spaces.

Abstract Currently, 73% of the water demand in Balikpapan was only supplied from Manggar Reservoir, and it will continue decreasing parallelly with the increasing population. Regarding the population issues and the government’s planning for the new capital city of Indonesia, Balikpapan will be a buffer city facing serious risk in water supply issues in the future. Therefore, this study seeks to analyze an alternative of water supply. Following the concepts in Water Sensitive Urban Design (WSUD), The rainwater harvesting (RWH) method was chosen for preventive analysis, and Institut Teknologi Kalimantan (ITK) as one of the reputable’s universities in Balikpapan will be taken as a study location. The results obtained that the monthly water demand in ITK was ranged from 3228.34 m3 to 16632.97 m3. Using RWH, water supply analysis was obtained from 3790.62 m3 to 10697.31 m3 in various rainfall durations (0.5 to 2 hours) and 20 years projections (2022 to 2042). Following the obtained water supply. This study also reveals that the savings of total water usage can be reached from 24% to 100%, and around IDR 14,082,002 to IDR 37,035,390 is converted to currency. The highest saving reached due to water supply meets the water demand.

Urban Planning And Design

Urban regeneration is challenged by contradictory process of globalization. This double-sided process can enrich local communities or leave them at margins of global society. Regarding globalization, most authorities claim that urban planning and design are in paradigm crisis. The crisis is an announcement for paradigm shift that is in contemporary theoretical and conceptual frameworks. They give hope for the ?light at the end of the tunnel?. Their common groundings are: ?soft and hard infrastructure?; ?agencies and structures?; ?power to?; ?new rationality?, ?common sense?; ?communicative action?; and ?integrative development?. The purpose of the research is to discuss possibilities of teaching method ?Integrative urban design game? for soft urban regeneration, elaborating it with respect to the crisis in specific context of building bridges among academia and local communities regarding various teaching approaches. The method was innovated at the Faculty of Architecture in Belgrade and tested in Bac community. The hypothesis is that the method provides soft infrastructure for urban regeneration in local communities. The research will result in a form of principles the game should be grounded on, using participative mimicry model of present and future place for overcoming paradigm crisis. Methodological approach is based on theoretical comparison, case study, and questionnaires among stakeholders.

Design Proposal

Urban design for high-intensity central urban areas often ends up with the conglomeration of high-rises, while these areas are then faced with the question as how reasonable planning and design approaches could be employed to reflect the green and ecological design idea, optimize the spatial and environmental quality and carry on the local traditional culture and features. To respond, this paper conducts a case study of the GIFC urban design proposal, and further explores the green and ecological design approaches with the local Lingnan characteristics from the perspectives of the macro-level ecological pattern, the spatial order as well as the establishment of the public space system, with the intent to offer some reference for the development of new urban areas.
