When I found that I could have a rain water tank installed on my property, I thought it was a great investment. It would be much more environmentally friendly that using a main waterline from somewhere, using up the water supply. I am very environmentally conscious and anything that I can do to help in any small way, I feel is worth my time. After I had mine installed, I found that there were so many things I could do with the water that I collected, I couldn’t figure out why I didn’t do this earlier on in life. Now, I don’t have to depend on any company to have good water.
