Rainwater harvesting or rainwater collection systems are simple ways of taking advantage of mother nature to reduce your water bill and become more green.

Rain Water Harvesting Barrels Or Cisterns

You can get started with an easy barrel or bucket under areas where rain comes off the roof.  You could easily make a downspout feed into a barrel.  Every 100 square feet of roof can yield 55 to 60 gallons of water per inch of rainfall. Irrigate using a shutoff valve and a garden hose. Amazon even sells Rain Water Harvesting Barrels.

Rain Garden

Store harvested rainwater in the soil by diverting roof downspouts towards shallow basins full of water tolerant plants.

More complex rainwater harvesting can be done using a living roof full of plants or a street curb side planter.
