The availability of public water supply is becoming increasingly challenging, particularly for non-domestic supply. Over the coming years this challenge will continue to increase as the water industry works to bring new large scale sources of supply online, compounded by growth and a changing climate (leading to a greater likelihood of low flow events and droughts). This project has focused on urban landscapes, particularly use of roof space to facilitate rainwater harvesting to meet non-potable water demands. However the principles of using rainfall capture to reduce reliance and demand on the public drinking water system is highly relevant to rural industries such as agriculture. This is an option that is already being considered in many areas due to the potential use of large roof areas on barns / agricultural sheds and similar space for the installation of water storage tanks.
