This trickle of water could cost you £1,000 per year

June 14, 2010

I noticed a trickle of water in the toilet, it continued even after the cistern had filled up. So I decide it was wasting water.  I wasn’t sure how much, so decided to take a measurement. 

With a jug, I collected water from the leak over one minute.  It came to 700ml. 

I then did the same again, just to check.  Again, 700ml.

Here’s how that works out:

 

• 700ml per minute = 42 litres per hour
• 42 litres an hour = 1.08 cubic meters per day
• United Utilities provide water at £1.37 per cubic metre, and take it away again
• At £1.17 per cubic metre.  So water down the toilet costs £2.54 per cubic meter.

• 1.08 cubic metres per day = £2.74 per day
• £2.74 per day = £1,000 per year (plus ten pence)
