Figures from the Central Statistics Office (CSO) show that Irish people are using less water.
The data was re-released to coincide with World Water Day on Friday.
The CSO said that domestic public metered water consumption fell by 8.4% between 2015 and 2016.
The annual average consumption per meter per day in 2016 was 351 litres.
This is an 8.4% decrease, compared with the 2015 average of 383 litres.
On a monthly basis, the average consumption varied from 342 litres per meter per day in November to 358 litres in May.
In contrast to average consumption, the median consumption per meter per day in 2016 of 249 litres was 1.2% higher than the 2015 figure of 246 litres.
The monthly medians varied from 246 litres in July and November to 258 litres in May.
Median consumption reflects typical levels of consumption more than average consumption, as the median is less affected by meters with very high levels of water use.
Around 75% of yearly total water consumption by domestic metered customers was accounted for by 99.1% of customers, using a consumption threshold of 1,000 litres per meter per day.
Some 0.9% of customers used 25% of metered water consumption in 2016.
Cavan had the lowest average consumption in 2016 at 298 litres, compared with Offaly which had the highest annual average of 398 litres.
The average consumption by Dublin postal district shows Dublin 20, at 274 litres per meter per day, had the lowest annual average daily consumption in 2016.
Dublin 24 had the highest average daily consumption at 569 litres.
