I'm not sure if everyone else knew this but me but........Did you know you can collect up to 500 gallons of water per 1 inch of rain on only a 1,000 square foot roof? Wow, i have been continually using my public (hard) water for plants, bushes, shrubs for years, not realizing i was losing this precious resource every time it rains. So, I went looking for quick inexpensive options and decided on a simple - single system with downspout rainwater diverter to my rain barrel.
Again, maybe everyone is already doing this, but i wasn't, and now very glad I did. Cheap, effective, & Green. The only problem now - Too Much Water! It overflows - So now it's time to connect another barrel - or two!!
