Abstract

Fresh water is a finite natural resource. Prolonged drought, record low inflows, population increase and climate change have increased the pressure on water authorities and conventional water supply systems. Additional measures such as demand management and the use of alternative water resources (e.g. recycled water and stormwater) have been considered by water authorities to ease pressure on the conventional water supply systems. Projects utilising both recycled water and treated stormwater in an integrated system have the potential to increase the security of supply and to improve water efficiency by using water supplies and water storages more effectively. The City West Water, the local water authority supplying water to the West of Melbourne (in Australia) had proposed to use combination of recycled water and treated stormwater through a novel approach of injecting treated stormwater into the ‘third’ pipe, which carries recycled water. In this new approach, mixing of the two types of water takes place inside the third pipe, in contrast to the current approach of using combined recycled water and stormwater treated and mixed at the source and delivered through the third pipe. This study investigated the issues and challenges that could be faced with this novel approach.
