Typical Household Water Usage
The CRU reported in 2019 that an average household in Ireland uses 125,000 litres (125 m3) of water each year, which is approximately 2,400 litres of water per week. Exactly how this translates into an amount of water used by each person depends on the number of people in the house; however, an average water usage would be 133 litres per person per day.
Importantly, this average weekly figure of 2,400 litres per household includes an allowance for the small number (7%-10%) of properties that have dripping taps and larger leaks. If a property has no leaks or drips, then the average usage per week should be about 20% less.
This text is based on the CRU decision of July 2019 on the IW Household Water Conservation Proposal.
*Did you know that checking for and repairing dripping taps could save 5,000 to 10,000 litres of water per year for each dripping tap? A leaking toilet, where water is continually running down the inside of the toilet bowl, could be losing 200-400 litres of water a day, or up to 145,000 litres per annum - which is more than the use of a normal house on its own. And if you have a leaking pipe in your home, it could be losing as much as 10,000 litres a day!
