"rain barrel"的定义和意义

What is a "rain barrel"?

A rain barrel is a container used to collect and store rainwater, typically from the roof of a building. It is connected to a downspout from a gutter system, allowing rainwater to flow into the barrel. Rain barrels are often made of plastic or wood and can vary in size. The stored water can be used for outdoor tasks like watering plants, gardens, or lawns, helping to conserve water and reduce water bills. They are an eco-friendly solution for using rainwater, especially in areas where water conservation is important.
