Figure 2 - Main OSD tank storage-elevation relationship




Figure 3 - Critical 1% AEP + 20% storage hydrograph: 25-minute burst, Storm 4




The storage-elevation curve provides approximately 75 m3 at RL 118.00 m. The critical hydrograph peaks at
approximately 74 m3, corresponding with the modelled peak level of RL 117.98 m. The storage
subsequently draws down through the adopted dual outlet controls.
