What Is Rain Garden System
A rain garden is simply a planted depression in the landscape.
What is rain garden system. As the rainwater and snowmelt runoff travels across the lawn and hardscape, fertilizers and pollutants are washed into the rain garden's natural filtration and cleansing system. A similar rain garden located farther from the home would need to be significantly smaller (1250 x 0.06 = 75 sq. Rain gardens rely on plants and natural or engineered soil medium to retain stormwater and increase the lag time of infiltration, while remediating and fi
The garden soaks up and purifies water resulting in cleaner water flowing to area rivers, streams, canals, lakes, ponds and harbors. It is designed to temporarily hold and soak in rain water runoff that flows from roofs, driveways, patios or lawns. If siting your rain garden closer than 5m (16ft) to your house, seek advice from a geotechnical adviser or registered ground engineering professional to avoid any damage to foundations by infiltrating water;
Rain gardens are effective in removing up to 90% of nutrients and chemicals and up to 80%. When you create a rain garden, which is a shallow, planted depression, it collects water that slowly soaks into the soil. A rain garden is a garden of native shrubs, perennials, and flowers planted in a small depression, which is generally formed on a natural slope.
• do not place the rain garden directly over a septic system. Principal components of the system include: Rain gardens, also called bioretention facilities, are one of a variety of practices designed to treat polluted stormwater runoff.
All water captured by the rain garden and all pollutants in that water are removed from the storm sewer system. Where it is practical to install a pipe leading to the main drainage system below the rain garden in case of excessively heavy storms • it may be tempting to put the rain garden in a part of the yard where water already ponds.
Remove pollutants from water before it enters surface waters. Add more organic mulch and topsoil to your rain garden to elevate the area and absorb the water quickly. The better a plant can handle wet feet, the closer it is placed to the center of the garden.
