The second day of my WATERTIGHT Challenge really was a day of two halves. It began with sense of real optimism that inspired by my finding that our 24 hour water use on Day 1 had been just 224 litres (112 litres each). In addition, I then took delivery of my new shiny rain gauge which I am going to deploy in the garden to show how much rain it takes to fill our water butts…very exciting…!!
Then things took a downturn. First, I had a look in the water butt and it was completely empty (the other two are currently out of commission). Then I looked at the recent rainfall data for Exeter, which showed that we had only 1-2 millimetres of rain in July, and then I looked at long term forecast and discovered that we were not expecting any rain for the foreseeable future…not much point having a rain gauge for that [and it still hasn’t rained significantly since – NP 07/08/2020]….!?
At this point, I got a bit carried away and, because we had used both the washing machine and the dishwasher already that day, decided to check the meter again in the evening. This time it showed that we had used 375 litres already on Day 2 (~188 litres each) and I realised how much effort this challenge was really going to take.
Roll on Day 3…!!
Determined to get to the bottom of our high levels of water use and having worked out everywhere we use water in our household, I decided to systematically assess how much of these activities used. The first target for investigation was the washing machine.
