    Abstract

    ![CDATA[Recycling of wastewater is important for achieving sustainable use of water in both urban and rural areas. Currently, in Australia, there are strict regulations on disposal and reuse of wastewater. Irrigation of sporting fields is one of the most common applications of wastewater recycling. However, there is an increased risk of soil salinity in the vadose zone when recycled water is used for irrigation. This is due to the generally increased levels of salt in the recycled water compared to that of town water supply. This paper presents salt transport modelling for a sporting oval (Greygums Oval) in Western Sydney which has been irrigated with recycled water for more than four years. The modelling was carried out for 1277 days using HYDRUS 1D, which is a one dimensional salt transport model. Meteorological data was used to specify atmospheric boundary conditions, which was collected from nearest weather station of Penrith Lakes, 4 km from the Greygums Oval. Average total dissolved solids (TDS) of recycled water varied in the range of 480-630 mg/L. Hydraulic loading rate and salt loading of applied irrigation water were 160 mm/year and 713 kg/ha/year, respectively.]]
