RiverSmart Homes - Rain Barrels

Rain Barrel

Rain barrels capture and store the rainwater running off your rooftop. The harvested rainwater can be stored for later use; released slowly over time to infiltrate properly; or used immediately to water lawns and landscaped areas, fill ponds or fountains, or wash cars.

Rain barrels come in a variety of sizes and shapes. Design improvements help eliminate the threat of basement flooding and also keep them from becoming breeding grounds for mosquitoes.

How a Rain Barrel Works

Rain barrels connect to the downspout from your roof. They should be located in an easily accessible area, not too far from the area where you intend to use the stored water (i.e., a garden or lawn).

To facilitate the use of gravity, rain barrels should be placed on the highest elevation that is workable, or on a small stand. Rain barrels should also have an overflow valve that directs water away from the foundation of your house.

Benefits of Rain Barrels to the Homeowner

Rain barrels require little maintenance and are a great way to save money and conserve water as a natural resource. With a rain barrel you can:

  • Cut your household use of water during the hot summer months
  • Water your plants with chlorine-free rainwater that they prefer
  • Clean your car, bike, tools, etc. without ever using the faucet
  • Save money on water bills

Benefits of Rain Barrels to the District

Rain barrels help reduce runoff that carries pollutants into streets, storm sewers, and local waterways. Rain barrels also:

  • Decrease municipal water use, lowering demand for treated water—especially during periods of drought
  • Increase soil moisture levels for gardens
  • Assist in recharging the groundwater table when emptied after rain events
  • Mitigate the threat of urban flooding when used on a large scale

RiverSmart Homes Can Help You Install a Rain Barrel

DDOE’s RiverSmart Homes program offers two rain barrels per property for a $45 copayment per barrel. Homeowners must sign up and receive a stormwater audit. Learn more about the process.

DDOE also offer the Rain Barrel Rebate Program for homeowners who do not want to wait for the stormwater audit or want a difference type of rain barrel than the one offered through the RiverSmart Homes program. Homeowners can purchase and self-install up to two rain barrels and receive $50–$500 as a rebate. More information, including rain barrel criteria and application materials are available.
