^aThe energy consumption for the groundwater pumps includes both the transfer and bore pumps, i.e. the energy for Pump G1 includes G1a (not modelling in EPANET, energy use estimated from volume) and G1b (modelled in EPANET)
^bThe total volume supplied by the stormwater schemes is measured as the combined volume supplied by Pumps S3a and S3b (which discharge to Suma Park Dam), while the total energy is the total of all pumps
^cThis is the volume supplied by the natural catchment for the town’s consumption, the total inflow from the catchment is greater than this however some is used to provide environmental flows and some spills
