The Olive Grove system operates with a capture basin on-line from which flow is pumped into a wetland. This system is currently operational. To achieve the predicted yields the existing site would require upgrading. Treated water is conveyed to Ridley Reserve for injection into the T1 aquifer. Drilling at the Olive Grove Site intersected 16m of T1 aquifer at the site. Subsequent well discharge testing suggested an injection capacity ranging less than 5L/s, against high pumping heads. Furthermore, the T2 aquifer is not prospective at this locality. It is therefore proposed to pipe the water and inject into the T1 aquifer at Ridley Reserve, where two T1 wells have already been established. The City of Playford has already constructed a 150mm rising main between Olive Grove and Ridley Reserve.
