Water Charges Made Simple – How Much Will You Pay?Guide-to-Water-Charges-In-Ireland

The Commission for Energy Regulation are expected to confirm the cost per litre of water in Ireland in the Autumn but a common figure people are mentioning at present is 0.0022 euro per litre which is 2.20 euro for every 1,000 litres we use.

Below I have broken down the main things we use water for in the home, estimated what each things costs and given a rough esimate on what water charges will cost a variety of different types of households based on the 2.20 euro  per 1,000 litre figure and the allowances that Minister Hogan has announced for different types of households.

You can Listen here to Podcast of Water Charges Interview with Sean O’Rourke on RTE Radio about this on Wed May 14th.

So what are the main things we use water for and what does it cost?

Drinking Water – It is recommended that we drink about 2 litres of water per day. Cost per year would be €1.67 per annum per person 

Baths – It is generally accepted that typically one uses about 80 litres every time they take a bath. This translates to 18 cent per bath

Showers – On average people shower for about 8 minutes per day based on a UK Report conducted by homecare products manufacturer Unilver.

Some showers particularly power showers have a water output about 17 litres per minute but let us be a bit more conservative and assume that your shower has an output of 12 litres per minute so you use 96 litres per day.

Based on this assumption it will cost you 21 cent per shower per person

Dishwasher – Uses about 25 litres per cycle – 5.5 cent per use 

Washing Machine – Uses about 50 litres per cycle – 11 cent per use

Washing Car – It is estimated that you will use about 300 litres on average each time you wash your car – 66 cent per wash

Toilets – Modern cisterns installed in last 10 years use about 6 litres per flush. Older ones can use 9 to 12 litres. Cost 1.3 cent per flush (based on 6 litre flush)

Other Water Usage – Brushing teeth, washing hands, water for cooking, rinsing a cup etc Allow for about 30 litres per day – 6.6 cent per day per person

Gardening – A difficult one to estimate but lets assume that you would only use water outdoor about five months of the year (May to September) and only on days when it is not raining. Because it is seasonal and it does rain I came reasonably conservative figure of about 20 litres per day when spread over the whole year. – 4.4 cent per day

 Water Usage Assumptions water-saving-tips-ireland

Further down I have estimated the costs per household per annum but it is important to point out first I am basing this on the following assumptions.

1: People drink two litres of tap water each per day in the home

2: Members of the household take 8 minute showers everyday and the showerhead releases 12 litres of water per minute.

3: All households use a dishwasher and washing machine and

– One person household uses dishwasher twice a week and washing machine twice a week

– Two adult household use dishwasher three times per week and washing machine three times per week.

– Five person household use dishwasher four times per week and washing machine five times per week.

4: Each household has one car that is washed at home once a month.

5: Toilets are six litre flush, each householder flush toilet 8 times per day but only 5 times a day in the home.

6: Each person in the household uses 30 litres of water per day through a combination of washing hands, brushing teeth, cooking, rinsing cups etc

7: Each household uses an average of 20 litres per day for garden and other outdoor use.

8: Figures are based on a 52 week year and does not account for holidays.

9: An allowance is also built in for visitors to your home and guests staying over.
