Rain barrels capture relatively small amounts of roof runoff, but the captured precipitation can be used by homeowners for watering gardens or yards, and provides a better understanding of the volume of water generated by rooftops. Communities or organizations frequently organize rain barrel sales, where large shipments of barrels can be sold at a reduced cost. Some companies will bring a truckload of barrels to your community and provide all the logistics in exchange for marketing assistance for the sale.
Helps delay the contribution of precipitation to a combined sewer system, extending local wastewater treatment capacity. Reduces off-site stormwater runoff contributions to reduce flood risks, and saves on your water bill by using greywater for irrigation rather than expensive, treated, potable water.
It doesn't need to rain much to fill the rain barrels, thus limiting their stormwater management and water reuse benefits.Also, water re-use opportunities are limited during the winter season.
