Total capacity:	133 ML/day
Date commissioned:	February 2009
Feed water TDS:	34000 mg/L - 39000 mg/L ^[1]
Product water TDS:	140mg/L ^[2]
Percent of water supply:	27% of South Eastern QLD
feed water temperature (low):	17°C
Feed water temperature (high):	28°C
Seawater intake system:	Submerged open sea
Pretreatment system:	Ferric sulphate coagulation, sulphuric acid injection (pH reduction), polyDADMAC, dual media pressure filters
RO operating pressure:	First pass RO operating pressure - 64 bar (45% recovery). Second pass - 15 bar (85% recovery) ^[3]
RO passes:	2 ^[3]
RO trains:	9, 3
Post-treatment system:	Lime stabilization, CO2, disinfection by sodium hypochlorite injection
Concentrate disposal:	Treated supernatant discharged to sea, solids centrifuged and landfilled
