Urban Water Conservation, Harvesting, and Reuse Ñ South Australian Case Studies
2001 •
Paul Downton
South Australia has a relatively long history of innovation in wastewater treatment and water conservation, spurred on by response to its predominantly arid environment. Examples of innovation range from those in private sector developments in inner-city contexts to suburban community projects. Treatment systems range from mechanical filtration to extensive reedbeds. Storage approaches include underground tanks and aquifer recharge. Most of the projects link water treatment to vegetation establishment as part of broader urban planning strategies.

Rainwater Harvesting and Urban Design in Australia
2012 •
Mahala McLindin
Australia has recently emerged from the worst drought on record. The so-called “Millennium Drought” has triggered a widespread change in water management approaches and practices. This paper outlines recent developments in rainwater harvesting and urban design in Australia and covers some of the key issues that need to be considered in the design and implementation of rainwater harvesting as an alternative source of urban water supply.
Harvesting the Urban Catchment in Warrnambool and Renton
Murray Dancey
The Warrnambool Roof Water Harvesting Scheme is an innovative Integrated Water Resource Management (IWRM) project for alternative water source adoption. The review indicates that the project is the only large scale operational hybrid roof water harvesting scheme in the world and therefore provides an excellent case study of the threats and opportunities provided by this innovative scheme. The projects gestation over more than seven years is reviewed and its compatibility with the principles of IWRM are assessed as well as an analysis of key indices from datasets is provided. The RWHS produced a framework and methodology to assess some of the costs and benefits of a comparable system and the results of this analysis is provided and reviewed. The city of Renton, Washington, United States of America has been selected as a candidate for a desktop analysis of the suitability for a RWHS system. The review of the city of Renton shows that while household water efficiency has enormous scope for improvement, a RWHS proposal for a new residential development could lead to substantial reductions in supply from traditional catchments. This review indicates that for cities with relatively high rainfall (> 700mm/y) a hybrid RWHS provides a compelling case for innovative and step-change IWRM practice.

Assessing the Impacts of Climate Change on Rainwater Harvesting: A Case Study for Eight Australian Capital Cities
preeti preeti
Due to climate change, freshwater supply will be limited at many locations around the globe. Rainwater harvesting (RWH) has emerged as an alternative and sustainable freshwater source. In this study, the impacts of climate change on water saving as well as the reliability of a RWH system are investigated using data from eight Australian capital cities. Both historical and projected rainfall data were incorporated into a daily water balance model to evaluate the performance of a RWH system in relation to its reliability, water savings and scarcity. Indoor (toilet and laundry), outdoor (irrigation) and combined (indoor plus outdoor) water demands were considered for a 5 m3 tank size. It has been found that in the future period, the water savings and reliability of a RWH system will reduce slightly across the selected cities. Different capital cities of Australia will experience different level of performance for a RWH system depending on their locations, water uses and seasons. The fi...

This study presents the impact of including decentralised rainwater harvesting, water efficient appliances and wastewater reuse strategies in analysis of the operation of regional water supply systems. These strategies provide significant reduction in regional water demand, improvement in regional water security, decreases in greenhouse gas emissions and economic benefits. A compelling case has been made for the inclusion of decentralised
