Practical notes on how to save water on...

Friday, 15 October 2010


as part of BLOG ACTION DAY [] -or- BAD ! I will be showing you how to make some simple steps towards using less water around your home.

How to use less water to flush the toilet - a quick resolution you can start using today....

If you have an old 13, 11, 9 or 7.5 litre WC consider fitting a water dispacement device inside your toilet cistern to reduce the volume of water flushed down the toilet every time you flush. 6 litre toilets were being fitted from 2001 in the UK to comply with new water regulations -this advice is not for a 6 litre or less system -its for older installations only! Some people might recommend using a hippo to do this - in my opinion this is not necessary, just get a plastic milk bottle -wash this out and fill it with fresh water, leave the top off and place it inside your cistern. You might need to try a 1 litre bottle instead, see what fits best. If its tricky to see what fits then turn off the water at the mains and flush the toilet to drain out the cistern, then take the lid off and see if one or two 1 litre bottles can be sat inside the cistern....

Remember any toilet needs 4 to 6 litres to perform a powerful flush. If you are not sure how big your cistern is 9 litres, 13 litres, 6 litres etc then measure the width depth and height of the cistern in centimetres and do the following sum:

width x depth (front to back) x height of the water in the tank

then divide the answer by 1000

this is the number of litres (generous estimate) that your cistern holds. The more bottles you get in the more water you save but don't over do it....

How much water will you save? well... it depends ....toilet flushing is probably about 30% of your water bill so if you cut it by 3 litres, say improving from a 9 litre flush to a 6 litre flush you have just saved about 10% of your water bill....

happy plumbing! .... and remember that's precious drinking standard water you are flushing down your toilet and even though you might find messing about with your cistern a bit gross -you are lucky! yes lucky! -some people in the world don't have a toilet at all which leads to a much more messy, stinky and altogether unsanitary existence!|Start Petition

Reading your meter

water meter. So... as I was saying before -if you do have a water meter it will (probably) read in cubic metres - this one shows 1285.4058 cubic metres. The red figures are after the decimal point.


For Blog Action Day 2010 I 'll be writing about how to save water on the 15th Oct but just for now I wanted to say the first step to saving water is actually getting a meter because having a meter shows you just how much water you are using. Saving water is just like going on a diet -like counting calories -you have to know where you're know where you are going to get to. Knowing exactly how much water you used last month really helps you to work out -am I doing OK? Could I be doing more? The average person in the UK uses about 150 litres of water every day or 0.150 cubic metres (which is what your meter will read in). So, in a month, you should use about 4.5 cubic metres per person in your house. The best new housing in the UK under something called "The Code for Sustainable Homes, Level 5 or 6", requires new houses to achieve 2.4 cubic metres per person per month. -How are YOU doing?
