Product Information

SuDS planters, or stormwater planters, are a sustainable stormwater management solution with their intelligent internal drainage system. With both bio-retention and additional internal storage, these planters are an innovative solution to property level retrofit SuDS and can work out as much less expensive than most groundwork interventions. In this way, the whole garden could be considered a rain garden. However, more commonly, the low-lying area or dip itself, is defined as the rain garden. Benefits of rain gardens A rill or channel of some kind will connect the roof downpipe to the dip. You can include other linking elements such as a water butt, rain chain, stormwater planter, or pond. To avoid weed growth between new plants, consider sowing a flower seed mix suited to the conditions to infill while plants establish The choice of plants will be governed by regional rainfall and speed of drainage. On a less well-drained soil (clay) or areas with regular heavy rain, plants tolerant of wetter soil may be needed. This is not a bog garden, however (i.e. it cannot be guaranteed to be damp all year round). For the base and inlet on moisture-retentive soils

You just need to make sure that the box is of a strong construction and that it is watertight. If it isn’t watertight, you can line it with PVC sheets (overlapping by 200mm and securing with PVC tape) or with a material such as pond liner. Be aware of underground services, such as gas and electricity, and dig carefully if you are not sure oftheir exact position. A rain garden should be located; 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 Leave a notch in the berm, with a gravel-filled channel for the water to exit into a conventional drainage systemCut off or divert the downpipe from the roof to flow into your raingarden planter. You may need to add a downpipe shoe to direct the water correctly. Placing large stones below the spout will prevent splashing and will help to filter debris. 6. Get planting: Add some gravel to the base of your planter and position the slotted pipe so that it drains down towards the outlet. Push the drainage pipe through the liner and connect up the overflow pipe. Seal up your pipes with silicon and tape. Add the remaining gravel to cover the pipes and top with permeable membrane to stop rainwater washing the soil out. Add a layer of sand and then fill with a mix of soil/compost to sand in the ratio 4:1. 5. Aim the downpipe The standard SuDS planters are drained via a perforated drainage pipe running along the bottom of the planter. A number of factors influence the drainage rate including the drainage pipe diameter,soil mix and therefore infiltration rate,impact of plants and soil conditions prior to any particular rainfall event will be important. This depends on the type of soil you have, the size of the roof and the drainage rate of your soil. This willdetermine how deep the rain garden should be. The space available will also govern the size. Even a small rain garden will control run off; it will just overflow more often. How to calculate the area of the rain garden Some shrubs such as Cornus sanguinea or even trees, such as Betula would be suitable for a large planter.

Water may discharge from a planter into the normal drains or it could be diverted further into a Rain Garden. Measure the surface area of the roof that will be receiving the rain (which will then run off the roof via the downpipe). The size of the rain garden is determined by the size of the roof and other impermeable surfaces that carry water. The depth usually varies between 10 and 20cm. If the area is sloping, the top end will require more digging out then the lower end. The spoil form the top end can be used to fill in at the lower end to make the rain garden level These planters are particularly useful in areas where a significant amount of rainwater travelling from the rooftop or other impervious surfaces flows directly into a drain causing flooding on one's premises.Even if you don’t have room fora rain gardenyou can still implement sustainable stormwater management. Rain gardenplanters, or gutter planters, handle rainwaterrunoff from rooftops and operate like a rain garden inside a planter. Larch produces its own intrinsic preservative providing a very long planter life without the use of toxic preservatives. Sustainable drainage systems have become increasingly popular in recent years, and for good reason. They mimic nature and generally manage rainfall close to where it falls. SuDS can be designed to transport (convey) surface water, and slow runoff (attenuate) before it reaches watercourses. A rain garden planter is filled with layers of drainage clay pebbles/shingle, and a specialist free draining growing medium. They are isolated from the water management system by a geotextile layer. The planter is lined to form a waterproof seal to retain the stormwater for regulated slow release.

When you incorporate a SuDS system (or any other drainage system), it must be submitted to the local planning authority (LPA) for your project. Non-native. Often late flowering. Clump forming. Several species on the RHS ‘plants for pollinators’ list. At the point where the water enters the rain garden, cobbles or gravel will help prevent soil washing away With both bioretention and additional internal storage, theseplanters arean innovative solution to property level retro-fit SuDS, and can work out very much less expensive than most groundworks interventions.Based on trial data, the narrower diameter is recommended to limit the flow out of the planter to a reasonable level to maximise the potential for flood storage, especially where extra storage was provided by the geocellular storage. One hour after a rainfall event begins, up to 0.75m 3of water can drain from the bottom of the planter.

Alternative materials are linked to non sustainable production issues from energy consumption to pollution or toxic issues. Use plants that attract pollinatorsand have seasonal interest. Plant in drifts e.g. 7 plants per square metre These sizes are based on large, but manageable and movablesized units using a fork lift. This offers practical sized units option to be used in combination to achieve the recommendation catchment areas stated above. Native plants are always recommended for rain gardens as they are well adapted to local growing conditions and support local wildlife, including birds and butterflies. A rain garden is dry most of the time. It usually holds water only during and after rain, and they drain within 12 to 48 hours. The berm will keep the water in the rain garden, so has to be well-compacted, around 30cm (1ft) wide and 10cm (6in) in heightTable 4*. Estimated maximum flow rate for a 68 mm downpipe, with water distributed into planter via a pipe set at approximately 1 in 200slope.
