How an inception scheme works? A system of bores and pumps take the highly saline groundwater from underground before it can enter the River. It is piped to the 400 hectare Stockyard Plain Disposal Basin 15 km south west of Waikerie. There the saline water is disposed of by evaporation and infiltration into the ground, and will not return to the River for thousands of years. The schemes are directly benefiting downstream of River Murray water. Irrigators in the immediate area are seeing the benefits of the lowered level of groundwater under their land, and healthy Murray flood-plain vegetation is beginning in some areas. Natural revegetation is also being encouraged around the basin near Waikerie - 135 species of birds now inhabit the area.
