Rain Barrel Information

Harvesting rainwater helps conserve water and protect our waterways from polluted runoff!

Rain Barrel

Did You Know?

One inch of rain falling on a 1,000 square foot roof can harvest 600 gallons of rainwater

By implementing a rain barrel system, you can:

  • Reduce water pollution as a result of rainwater runoff which carries pesticides, fertilizers, sediment, oil, and trash into local rivers and lakes.
  • Reduce soil erosion and improve the ability of water to infiltrate the soil at a reduced intensity.
  • Reduce dependency on the municipal water supply and see a cost savings on your water bill.
  • Treat your garden, plants, and lawn to clean and free rainwater and help save energy by reducing demand on our drinking water supply!
