Subsurface drainage flows at two urban sites in Perth, Western Australia were shown to be feasible for water supply, providing multiple times the public open space irrigation demand. Subsurface drainage water quality is generally better than pre-development groundwater. It is suitable for irrigation with treatment for iron and hardness, while managed aquifer recharge will require treatment for iron, nitrogen, organic carbon and total suspended solids. Estimating post-development groundwater mounding can inform costly fill importation requirements. It is challenging to accurately estimate mounding, however 3D models are preferred over simpler 1D and 2D approaches.
