Abstract
Resource recovery by recycling wastewater is important for achieving a sustainable and secure water supply in urban areas. However, the current, but limited, literature suggests that there is an increased risk of salinity in the vadose zone of soil that is irrigated with recycled water. This is due to the presence of increased levels of salt in the recycled water compared to that of town water supplies. A laboratory column study was carried out to investigate the accumulation of salt in the vadose zone due to continuous application of recycled water over a period of 100 days. Soil samples were collected from a paddock located in the Hawkesbury campus of the University of Western Sydney, Australia. This paddock has an irrigation history of over 18 years using recycled water as part of the Hawkesbury Water Reuse Scheme.
