Rain gardens are small depressions constructed to collect rainwater runoff from roofs and/or driveways and lawns. Within the rain garden the water is allowed to absorb or infiltrate into the soil and filtered through the vegetation and root systems. They are typically planted with a variety of native wildflowers and grasses suited to periodically wet conditions.
The primary purpose of the rain garden is to reduce the amount of water being conveyed to the local stormwater system or surface waters. Even if water is not absorbed into the ground, the vegetation filters the water, reducing pollutants going into the stormwater system and ultimately our lakes and streams. Less water in the system also reduces downstream flooding. A rain garden is an efficient way to address stormwater issues by addressing them where they begin.
The more runoff you collect the more rainwater will be absorbed into the ground and replenish ground water levels. Water not absorbed will be cleaner than when it feeds directly into the stormwater system and it will not enter the system as quickly.
