  • 1. Ponds and Water ManagementThe detailing of external systems such as rainwater harvesting, grey water recycling, drainage orwater features may be conveniently addressed as part of the garden and landscape scope.Water Features, Ponds and Natural Swimming PoolsFormal or informal ponds, and fountains or other water features, are popular and useful designfeatures. However, designing, constructing and planting water features calls for a blend of gooddesign – balanced and harmonious with the surrounding gardens and house – together with soundtechnical knowledge. A wildlife pond, optimised for invertebrates such as dragonflies anddamselflies, can be an ecologically attractive feature, where space permits. A natural swimmingpool is reliant on the purifying effect of the root systems of certain aquatic plant and does notneed chlorination, so swimming is much more pleasant (and a natural pool will pick up quite abit of solar heat, without being artificially heated).Reed BedsReed beds provide an ideal medium for cleaning dirty water, where space is available, and canachieve a high discharge quality. They have the advantage of being aesthetically pleasing, verylow maintenance, and providing an attractive habitat for invertebrates such as dragonflies anddamselflies. A reed bed can be subtly integrated with ponds and other water features, mitigatingthe area needed. This provides a good opportunity for saving and storing “grey water” -wastewater from showers, baths, washbasins (and sometimes washing machines and kitchensinks) – which can be reused once treated, either for garden irrigation or in the home. (Untreatedgrey water may be unsuitable for long term irrigation, depending on its source.) Reed beds alsohave an important role to play in attenuating storm water flows, as part of the drainage strategyon larger sites.Water ConservationRainwater capture and storage is a straightforward way of reducing drinking water consumption,either for use in the home or for irrigation (although the water supply isn’t necessarily as reliableor consistent as grey water). The design, function and location of any rainwater harvestingsystem should ideally be considered early in the landscape design process, and the specificationand installation may be usefully included within the landscape works scope, rather than beingretrofitted at a later date.DrainageMany gardens, especially those on poor draining soil, suffer from waterlogging during wetwinter periods. The problem is often made worse by recent construction work, where soil hasbeen compacted by builders vehicles. Aside from soil remediation, and assuming the cause isnot attributable to a high water table, some form of drainage may be necessary. This can

Consideration should also be given to drainage of pavedareas such as patios and driveways. Drainage design, and compliance with the SUDS regulations,is a standard consideration in our garden and landscape design process. For more details visitGarden Design Wiltshire website.
