What is a rain barrel?

A rain barrel is a system that collects and stores rainwater from the rooftop that would otherwise be lost to runoff and be diverted to our neighborhood streams and storm drains. You may be surprised by the amount of water you can harvest: one inch of rain on 1,000 square feet of rooftop creates over 600 gallons of water!

Harvesting your own rainwater provide benefits for the environment and you. Rain barrels:

1. Reduce the amount of runoff that reaches our streams
2. Provide plants the water they like
3. Save energy and money used when water is processed to drinking quality standards Save you money on your water bills
4. Provide water during drought periods

Build your own rain barrel.

Rain BarrelsSafety Considerations

There is a lively discussion on line about the safety of harvested rain water. We would not recommend using harvested rain water for consumption. Watering plants is the best use and that raises another question. Is it safe to use harvested rain to water plants you will eat? The definitive answer is…it depends! It depends on your roof and what washes off your roof. The potential contaminants are metals that may leach from asphalt shingles. In general, we think it is safe to water your vegetable gardens with harvested rain water. However, the surest answer is to test your harvested rain water. To test your water in Nashville contact:
