thisplace.com.au - WaterWise Watering and Irrigation Systems

There are a wide range of watering systems currently available on the market, ranging from the sophisticated, to the simple hose and sprinkler. No matter which system you use, there are a number of basic rules to follow when using a garden irrigation system.

Water in the early evening or early morning because less water is lost through evaporation. (Never water in the heat of the day. It wastes water and can lead to plant damage from burning).

Disease susceptible plants such as tomatoes should only be watered in the morning so leaves are as dry as possible at night.

Water the roots, not the leaves of your plants. (Plants absorb water and nutrients through their root system, so the most efficient way to water is to deliver the water direct to the roots.)
Don't water when it is raining. (People with automatic watering systems need to pay particular attention to ensure these systems are switched off during rainy periods.)
Do not water paths or driveways.

WaterWise irrigation is about delivering the right amount of water; at the right time; to the right place.

How much water you apply and how often you irrigate depends on the type of plants, type of soil, climate and the time of year. Your irrigation professional or local nursery will be able to offer you advice on how long to water and how often to water your plants.

Hose and Sprinkler Users

Gardeners using hoses and sprinklers can be as efficient as those who have automatic irrigation systems, simply by planning their watering and sticking to a pattern. Tips for reducing water use when using a hose and sprinkler include:

Use a tap timer so you can't overwater if you forget to turn off the hose.
Make sure your hose, sprinkler and fittings are in good condition. Repair leaks and tighten up the fittings.
Use a part circle sprinkler close to buildings and roads to avoid overspray onto paving.

Improving Water Efficiency with your Existing Automatic Irrigation System

If you already have an automatic system, there are many ways you can save water and still maintain a healthy garden. Some tips include:

Check the system for nozzle blockages, or to see if foliage is interrupting spray patterns.
Replace the nozzles if they are worn.
If you notice a dry patch, put in an extra sprinkler - don't overwater the rest to compensate.
Check the operating pressure. The pressure can change over the years and your system may need changes to cope with a lower, or even higher pressure to remain efficient.

Note: ensure that you check with your local council regarding current watering restrictions.

What to look for when purchasing a New Irrigation System

An automatic irrigation system can be a great way of increasing your leisure time, efficiently watering your garden and saving water. A few things to check which will ensure trouble-free system operation and years of water savings.

Ensure the person designing the system is an Irrigation Association of Australia (I.A.A.) member. This is a voluntary industry association, but they can help should any conflict arise.
Look carefully at the plan. It should have separate sections for lawns and gardens. The sprinklers should throw away from the road, drive, house, paving etc.
Get a written quote and buy a multi-program controller, which separates lawns and gardens.
Fit a master valve and ensure the plumbing connection is done by someone qualified.
Find out the application rate of the different sprinklers used in the system so that you can schedule your controller. Your irrigation specialist can provide this information.
Question the selection of sprinklers - are they best suited to your application?
Use micro-irrigation in garden beds and drippers on native plants.
If you are in a windy location, use a large droplet size sprinkler to minimise wind drift.
Ask for the features of the controller to be fully explained. Make sure it lets you water lawns and gardens separately.

For maximum water efficiency, change the setting each season.
