Rain garden plants capture 30% more water than a regular lawn and filter that water into the ground. This reduces the amount of water containing household fertilizers, pesticides, oils, and other contaminants coming from our roofs, lawns, driveways, or …

In this project, you will create a miniature rain garden with loose potting soil and test how well this rain garden reduces runoff and filters out pollution. Look at the Variations section for ideas on other types of rain gardens and how to test the performance of these rain gardens.

2024年11月4日 · Rain gardens are eco-friendly landscapes designed to manage stormwater runoff effectively. They use natural processes such as absorption, infiltration, and evaporation to filter rainwater, thereby reducing pollution, preventing flooding, and …

2024年10月19日 · Rainwater from hard surfaces like roofs and driveways carries pollutants. Rain gardens catch this runoff, letting it soak into the ground slowly. This prevents flooding and helps recharge groundwater. They are planted with native plants that filter out pollutants. The soil in a rain garden also filters rainwater before it reaches the water table.

2023年12月9日 · A well-constructed and maintained rain garden can remove up to 90% of the pollutants present in rainwater runoff and can absorb significantly more water than conventional landscape areas such as lawns.

2024年6月9日 · By capturing stormwater runoff, rain gardens reduce the strain on local sewer systems, which can decrease the risk of flooding and water pollution in nearby lakes and rivers. This process helps preserve our natural water resources and supports a healthier ecosystem.

Rain gardens capture runoff and slowly filter out common pollutants and sediment. Less storm water runoff — runoff can cause erosion and often carries pollutants from streets and other paved surfaces. Reducing the volume of this contaminated water running into sewer drains helps reduce polution flowing into local waterways.

2024年10月9日 · Stormwater runoff causes soil erosion, which can reduce soil fertility and make it harder to grow plants and food. A rain garden can slow erosion by capturing and slowing the stormwater’s flow. When it rains heavily, the garden absorbs the excess water and helps to maintain the landscape’s integrity.

2024年10月28日 · These ingenious gardens serve as nature-inspired systems designed to capture and absorb stormwater runoff, mitigating water pollution while elevating the aesthetic appeal of any landscape. A rain garden is essentially a shallow depression planted with native vegetation, aimed at holding rainwater runoff until it naturally infiltrates the soil.

2020年6月4日 · A rain garden is a shallow area designed to collect and filter stormwater runoff. Rain gardens catch water that would have flowed into the street or flooded your yard, and they naturally clean and release that water into the soil.
