Some of you may know that I have an occaisionally written Blog called “Commitment 2010“. It deals with a little personal project for 2010: reducing energy and water consumption by at least 10% in the year.
Tonight I published a new post closing out the results for the water reduction piece for the year.
- 25% reduction on the three year average usage
- Four person family with young kids consumed just over 100 kL in the year
- Savings of greater than $100 in the year
The last one I didn’t touch on in the post. Installing a Water tank was never going to be a return on investment exercise – at this rate and with the cheapness of water here in Sydney, we are looking at at least 10 years before break even. And that’s not even considering the increased electricity use from having a pump deliver water from the tank to Toilets and a Washing Machine.
However, as an exercise in reducing consumption, it is pretty clear to me that if all new and renovating houses in Sydney were forced to include some form of water reuse or storage, it would have made the Desalination plant even more pointless than it already is.
