Average use for 1 adult household

Monsclara

What is the average use for a 1 adult household per year in cubic metres (metered billing)?

Irish Water: Mairead

Hi Monsclara,

Thanks for your query.

The combined charge per cubic metre (1,000 litres) for both water in and water out is 3.70 euro. Therefore the cap would come into effect should the customer use more than 43,243 litres in a year for a single person household.

However, if you would like us to look into your meter readings or check on your account, please PM the following details:

- Name;
- Address;
- Contact number; and
- If you are the account holder.

Once we receive these details, we will be more than happy to help.

Kind regards,
Mairead

We sent you a PM last week. Can you confirm if you have received this?

If not, we will be happy to resend it.

Kind regards,

Yes you sent me a PM - here's the transcript:

"Thanks for getting in touch and providing these details.

I suggest that you try a few of the steps found here to determine if you have a leak.

We would also suggest the following:

- Take a meter reading.
- Turn off your water and any appliance that may use water.
- Wait one hour.
- Take another meter reading. 

If the meter read has increased, it could suggest that there may be a leak in your home. 


I have also requested that this be investigated by the relevant department. 

Your reference number is: XXXXXXXX
I will follow up on this for you and as soon as any update is received, I will let you know.

Kind regards,
Mairead"


How does this answer/address my original question which was:


"What is the average use for a 1 adult household per year in cubic metres (metered billing)?"

Hi Reps

I would also be interested in the answer to the OP's question. What is the average annual usage, for a 1 adult, metered household? Surely it shouldn't take over a week to answer the question and supply this very basic information?

Hi Monsclara, Jack Killian and Mav11,

Each person consumes roughly 150 litres of water each day. This equates to 54,750 litres of water per person, per year on average.

I hope this helps. Feel free to let us know if there's anything else that we can help you with.

Kind regards,
Amy

I thought the 150 was contradicted months ago, with the average now down to 85 to 90 litres per day ?

http://www.irishexaminer.com/ireland/most-households-only-using-250-litres-of-water-per-day-392465.html

Obviously that would be a little higher for an individual on their own, with some usage applying to a household regardless of the number of occupants, but is there anything more up-to-date than those figures ?

Even IW itself requested a revision of the figures from the CER, reducing it from 150 to 111 litres to exclude outliers - it's in IW's own submission!

http://www.cer.ie/docs/000979/A%2003%20CER14408%20-%20Irish%20Water%20%20Water%20Charges%20Plan%20Submission%20Supporting%20Information.pdf

Why is the old figure being suggested by IW's reps here when their own submission contradicts it ?

Jack Killian

Three days on and no reply? Has IW been closed down already ?

I can't imagine a 1 adult household using 150L a day  , but maybe this figure includes in and out , which would put actual usage at 75L p/day

It was never actually 150; those were outliers used to convince the gullible that we "needed to conserve".

The previous peak-of-usage-curve estimate was approx 120, and they've revised that down to 85 since, hence my query as to why reps of the "utility company" supposedly in charge of water is relaying misleading information which contradicts their own submissions to the CER and their own engineers.

Hi Jack Killian and allthedoyles,

From our meter reading of a 3-month period in 2015, the average consumption for a typical property with one adult occupant was calculated to be approximately 148 litres of water per day. That would equate to about 54 cubic metres of water per year for that one person. This example is based on properties where there are no leaks or extremely high levels of consumption that would distort the calculations.

There have been some questions about why we have reported lower figures elsewhere. This is because the amount of water used per person increases in smaller steps as more people are living in the property. In other words a house with 4 people does not use 4 times as much water as a house with one person. For example, a family of 2 adults and 2 children would use 119 m3/yr, which is only 82 litres per person per day. As the numbers of persons increases, the consumption per person drops.

An average property, with average occupancy rates, uses about 114 litres/hd/day, based on our metering data gathered to date.

We hope this information helps.

Kind regards,
Amy

Hi Amy

I already acknowledged this above:

Seem to be close enough to the CER submission, but completely at odds with what the IW engineer was quoted as saying / what the article reported ?

The average household contains three people according to CSO figures, so that means we are using just over 80 litres per person.

It doesn't to be honest, as it's completely unrelated to the original question, which was regarding a one-person household.
