Rain Barrel

Since it seems to rain and rain and did I mention rain in the Charlotte area, now might be the time to discuss the rain barrel.

Composters.com has a fantastic explanation of rain barrels and there uses.  Residential watering uses 40% to 50% of domestic watering.  A rain barrel would allow each domestic user the ability to water their own yard and harvest the run off from their own house.    Interesting 3 facts about rain barrels

• Rain barrels conserve water and help lower costs (a rain barrel can save approximately 1,300 gallons of water during peak summer months).
• Rain barrels reduce water pollution by reducing storm water runoff, which can contain pollutants like sediment, oil, grease, bacteria and nutrients.
• Rain barrels are inexpensive and easy to build and install.

I wonder what the water savings would be for Rain Barrels in Charlotte?    I also wonder on the tax implications on the Charlotte City Budgets if everyone used a rain barrel!
