"There is an increasing trend to install a rainwater tank in the urban situation. However, it is critical to the success of integrated roofwater harvesting systems that processes be established to ensure thatsystems are properly designed and installed. This Guidance Manual for the Design and Installation of Urban Roofwater Harvesting Systems in Australia was commissioned to address the gap in availability of information relating to roofwater harvesting systems in the urban environment. The Manual is to provide guidance on the inter-related issues of site design,
materials and system components, including treatment and plumbing configurations, with the focus on water quality."
