• Have you ever wondered what is the difference between rainwater and stormwater? What about the differences between potable water, grey water and black water.

    Rainwater is drops of fresh water that fall as precipitation from clouds. Stormwater is that portion of rainfall that does not infiltrate into the soil and runs off roofs, roads and other impermeable surfaces where it flows into gutters, drains, rivers and creeks.

    Potable water is water that is of sufficiently high quality so that it can be consumed or used without risk of immediate or long term harm. Potable water often has to meet government regulations in relation to contaminant levels and is physically and chemically treated to achieve these standards. Grey water is non-industrial wastewater generated from domestic processes such as dish washing, laundry and bathing. Blackwater is wastewater which is loaded with biological material such as faeces and urine. Blackwater can also be referred to as sewage or brown water.
