The average Australian household uses between 150,000 and 200,000 litres of water each year, depending on location, climate, and lifestyle. That’s around 400–550 litres per day, with outdoor watering, showers, and appliances making up the bulk of residential water consumption. Installing a Polymaster rainwater tank can help reduce reliance on mains supply and support sustainable household water use across Australia.

Average Household Water Consumption

According to average water use statistics in Australia, each person uses about 150–200 litres per day. A four-person family can therefore consume 600–800 litres daily, adding up to roughly 220,000 litres per year.

Hot regions or properties with gardens use more, while homes with water-efficient fixtures and appliances consume less. Understanding your household’s annual water usage helps determine the right household water tank capacity. For instance, a 10,000 to 20,000 litre rainwater tank can cover several weeks of supply, act as backup during restrictions, and reduce bills long-term.
