This is just a suggestion, but, has anyone every tried a rain barrel catching system? They are efficient, cheap set up, one could actually set a system up from stuff at home, and you can really save a lot of money from set one of these genius ideas up! Another thing you can do with them is create thermal energy, and realistically hook it up to your main water supply. I use two 55 gallon blue hard plastic barrels or reservoirs, known to some people that use them for different things. Overall I would invest in this to anyone that is trying to cut down their water bill and/or their overall utility bill. It conserves water as well, obviously, so you are adding to the alternative energy output that I believe everybody in this world should at least have some input on. If we do not, then first, we will start to run out of good water which is a huge crisis and two, just like with everything else in the world, water prices will go up as there will be less abundant amount of usable water out there. So, if anyone actually has ever used or is using them, tell me how you like it, how much it cost you for the initial investment, and how long you've had it. Thank you everybody, and lets go green!
