Saving water outside

Woman watering plants

A large amount of all residential water is used outside – on our lawns and gardens, and washing of cars and driveways. But there are numerous ways you can dramatically reduce your water usage in the outdoors.

 

Know your soil type

Different soils retain different volumes of moisture as demonstrated in the table below.

Soil Type Sand Loam Clay
Water (mm stored in 20cm depth of soil) 12mm 42mm 28mm
     
  • Plants in sandy soil will require more water to survive as the soil retains relatively little water.

  • However, applying more than 12 mm of water on sandy soil at a time is a waste of water, because it will simply drain through, past the root zone.

Watering

Tips

Planning irrigation for your garden 

When planning a new irrigation system or modifying an existing system you should select the system and emitters which are efficient and appropriate for your:

For example, drippers are an excellent and water-wise irrigation option for most gardens, but may not be suitable for sandy soils.

You should consult your local irrigation professionals, horticultural specialist or nursery to determine which system(s) are right for your garden. Your irrigation specialist may design a different type of system for different parts of your garden.

Take a simple plan of your garden along to your local retailer or irrigation specialist so that they can help you design a system which will distribute the right amount of water in the right places.

Installation of new irrigation systems

If you are planning to install a new irrigation system for your garden then you will need to be aware of, and comply with the Efficient irrigation for water conservation guideline.
