Product Information

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 Rain garden planters are an attractive adaptation of sustainable drainage systems (SuDS). They are designed to manage rainwater runoff from domestic, commercial and industrial roofs. They collect roof runoff and function as a rain garden within a planter, allowing for sustainable stormwater management. For the rain garden to collect the optimum volume of rain, the longer side should face up the slope With a minimum planting layer of 450 mm and further 50 mmgap to the top of the planter, this would leave approximately 300 mm for a sub-base / storage layer.

Non-native. Often late flowering. Clump forming. Several species on the RHS ‘plants for pollinators’ list. 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. Plant with a variety of hardy perennial plants which can tolerate dry periods as well as short periods of flooding. Choose a mix of plants which can provide interest year-round and help to attract pollinators. 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. First, have a look at the downpipes coming off the roof and think about where could be a good place for a planter. Is there somewhere where you think people would enjoy watching the water splashing down, a place where it might be nice to sit next to plants, or a place where someone could look at the plants growing in the planter outside the window?When you have found a suitable drainpipe, you need to make doubly sure that it is a rainwater pipe, and has not had other pipes connected into it. See if you can see the gutter that is feeding it and follow the line of the pipe down the side of the building.

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. 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;

Sustainable Drainage Systems (SuDS)

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. 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. If you’re feeling inspired to now create your very own Green Roof, make sure you let us know on social media! Stay tuned for exciting projects on the horizon. 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.

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. Use plants that attract pollinatorsand have seasonal interest. Plant in drifts e.g. 7 plants per square metre Alternative materials are linked to non sustainable production issues from energy consumption to pollution or toxic issues. Drainage systems can contribute to sustainable development and improve the places and spaces where we live, and work by balancing the diverse challenges and opportunities that impact urban design and community development. To avoid weed growth between new plants, consider sowing a flower seed mix suited to the conditions to infill while plants establish

Some shrubs such as Cornus sanguinea or even trees, such as Betula would be suitable for a large planter. To properly locate the rain garden, first, need to know where the rainwater comes from. Gutters are one of the main sources. If one of them is connected to a larger roof area, it will carry more water to the land. 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.
