Published on

Adelaide’s water supply comes from reservoirs, Murray water accessed via the Mannum pipeline, stormwater, groundwater, waste water and localised systems. Then Adelaide metropolitan area comprises of four major catchment areas and four wastewater treatment plants. Adelaide stormwater generates around 86 giga litres per year. Only 10% of this is currently being re-used.
