Sourcing water around Australia

HAVE you ever thought about where your water comes from?

Sure it comes out of your tap or irrigation sprinkler, but do you know where the water starts?

Australia relies on many different water sources to provide its water needs.

Surface water: Can be found in a stream, river, lake, wetland, ocean or a dam.

Groundwater: Occupies the spaces between particles of soil (sand, silt and clay) or rock beneath the earth's surface. Found in unconfined (shallow) aquifers and confined (artesian) aquifers. Unconfined groundwater occurs near the land surface and receives direct rainfall recharge. Confined groundwater occurs beneath a layer of impervious material and may be under pressure.

Desalinated water: Desalination is the removal of salt, especially from sea water. It can provide a source of clean drinking water to areas that cannot rely on rainfall, particularly during drought.

Stormwater: Rainwater that has run off roads, roofs, paved areas, etc, usually conveyed by constructed drains

Wastewater: 99.97 per cent of water. Comes mostly from showers, baths and washing machines. Used water enters a wastewater pipe and then into the sewer mains, ending in a wastewater treatment plants.

Recycled water: The use of treated wastewater or drainage water. Can be used for a range of purposes. Recycled water is treated, according to stringent health regulations, to meet a standard for its intended use. Increasing the amount of recycled water is vital to maintaining a reliable, safe and sustainable water supply and becoming climate resilient.
