The reference to the pool was a bit of justification in our heads that we aren't just using 11000 litres of water and that we can justify filling the pool as we have captured more than we have used. Looking at a storage systems from someone like http://www.rainwaterharvesting.co.uk/ they have an excellent excel spreadsheet to give you some calculations and the 3750 litre tank they recommend is around £2,500 so $4,000 but this is for a full kit and not just the tank. I'll go through the ROI in a follow up post shortly but at about €1 per m3 of water at present in France this isn't going to pay for itself any time soon. This is more about being responsible users of the resource. No no no the pool is going to be a pool.

They have a 10,000 gallon tank for $4400. I realize you're not in the U.S. so those figures are just for comparison. As for ROI, if you're looking at money saved by installing a rainwater system that provides non-potable water for your entire home, it would take years to get your money back in savings. A $4,000 investment would take roughly 15 years for me to break even. Not sure how things would add up in your neck of the woods, but money saved isn't a determining factor where I'm at. Unfortunately, water is so cheap around here it's taken for granted. I think you do rain harvesting either out of necessity - you live in a region that receives very little rainfall per year or simply because you care a great deal about the environment. Either way, I think you're doing a good thing. Cheers! So are you planning to use a pool to collect the water rather than a water storage tank like what you can find at plastic-mart.com?

Also on Tuesday morning we have a meeting with the local mayor (the Marie in France) to find out out cost per cubic meter of water, so i should be able to provide you some rough ROI figures shortly. Many thanks for participating in the blog. Lee <em>PS: Don't forget to click the Google ads that way i can actually afford to buy the rain water system;)</em> Hi Jason,

I'll be keeping up on it regularly. I did some research into rain harvesting on my site as well - though on a much smaller scale. It's some pretty intriguing stuff. Your calculations are quite convincing, though I'd be interested in seeing the ROI for a rain harvesting system of this size. Best of luck with your green renovations. Look forward to reading more.
