WARRNAMBOOL'S REGIONAL ROOF WATER HARVESTING: A Toolkit has been developed to explore the potential for regional roof water harvesting in local towns

摘要

This paper outlines how harvesting of water from clustered house roofs in growth corridors is able to meet much, if not all, of the increased demand for water from growing towns and cities. The unique aspect of this principle is that water is harvested from all the roofs in a suburban subdivision via an independent pipe network that collects the water for further treatment as part of the town water supply. The regional roof water harvesting principle has been adopted for a growth corridor in Warrnambool, Victoria, providing a demonstration of how it can be successfully applied.rnGiven that the population growth areas are concentrated along the coastal strip of Australia that typically has an annual rainfall of greater than 700mm, there is significant opportunity to use this principle. A Toolkit has been developed for those responsible for water resource planning to explore the opportunity of regional roof water harvesting in their towns. This paper also outlines the structure of the Toolkit and its power to explore opportunities to utilise this source of water in growing communities.
