Rainfall is becoming predictable therefore a significant part sustainable garden design preparation is related to the direction of rainwater and in our climate.


Bans are may last for more than 6 months in times of drought and now prevalent – although flash flooding are still terrorizing the state.


As it rains, water from hard surfaces and all buildings is steered to the system via gullies, drains and downpipes. Some downpipes in the roofs of properties are steered to a thus and soak-away come back to the water table but in urban areas, or that the water is hauled into drainage systems.


This water control system not only creates our invoices more costly (with continuous repairs and drainage systems needing to be constructed to deal with peak rain) however groundwater levels fall as the water does not come back to the water and so we suffer from water shortages.


The home roof in the sheds some 45,000 liters of water every year that means that almost 25 can be harvested out of our roofs.


The easiest way would be to utilize diverters and feed into rain barrels or water butts — but on a scale that is big this can appear.


An alternative, is that the storage of in an underground tank water and rainwater. This is a solution since the water used to flush toilets, nourish the machine and irrigate the lawn and could be pumped from the tank. Surprisingly, only 5 should be drinking water therefore it is a solution that is beneficial.


There’s absolutely no real incentive to employ water recycling systems that are gray. A component of the issue could be, so manufacturers have a tendency to over specify so as to cover themselves and that this technology is fresh which pushes prices up. Because the water distribution system gets unreliable with all the climate, water harvesting will get not as much of a luxury and more of a requirement.


With rain and the frequency of flash flood, flooding tolerant plants are getting to be an increasingly significant part the backyard designers. Some hints of flooding tolerant plants are recorded below:


Flood tolerant ornamental grasses

  • Arundo donax
  • Deschampsia cespitosa
  • Miscanthus sinensis
  • Panicum virgatum


Flood tolerant perennial plants

  • Aster novae-angliae
  • Iris pseudacorus
  • Lythrum salicaria
  • Viola pedata


Flood tolerant garden shrubs

  • Cornus sanguinea
  • Ilex verticillata
  • Ribes nigrum
  • Salix caprea


Flood tolerant garden trees

  • Alnus rubra
  • Betula nigra
  • Liquidambar styraciflua
  • Taxodium distichums


With careful preparation, gardens could be made to add solutions for drought and handling rainwater. Flood tolerant plants can be a helpful tool in garden layouts and planting.
