Stormwater is rain. During heavy rain, when water is not absorbed by the ground, it needs to be collected so it doesn’t cause flooding. Stormwater is not treated. It flows from downpipes and other stormwater drains directly into the public stormwater network, which empties into streams and the sea at selected points.
Wastewater (sewage), is the used water that goes down sinks, washing machines, shows, baths and toilets. Most of it is water. The rest includes organic matter such as human waste, food scraps, cooking fats and oils, and debris such as sand grit and plastic.
Wastewater drains into gully traps and private wastewater pipes on your property. These connect to the public wastewater network, which carries your household wastewater to a treatment plant.
