Sprinklers & irrigation

Different types of sprinklers have different watering rates.

Ensuring your system is using the correct watering rate can save you money and water in the long run.

Use this guide to find the recommended run times for watering your garden, depending on which sprinklers you have.

Seasonal adjustment setting

As the seasons change, so do the water needs of your lawn and garden. The table below shows the adjustments that should be made to your irrigation controllers 'Seasonal Adjustment' setting to avoid over watering.

These adjustments are most suited to Perth and the South West.

No matter what the season, your controller should always be turned off when it's raining.

Time of year Seasonal adjustment
January–February 100% 
March 80%
April 60%
May Manual operation of the controller as necessary
June–August System turned off (winter sprinkler ban)
September Manual operation of controller as necessary
October 60%
November 80%
December 90%
*A permanent winter sprinkler ban applies to scheme and bore water users in Perth, Mandurah and parts of the South West and Great Southern regions between 1 June and 31 August each year.

Testing your sprinkler application rates

Catch cups (graduated measuring containers) are a valuable tool for testing how efficiently a sprinkler system is operating and the sprinkler application rates.

  • Spread catch cups or indeed any sized containers randomly around the watering zone. 
  • Make sure they are at least 1 metre from the closest sprinkler. 
  • Time how long it takes the sprinklers to fill the catch cups to the depth required. For example, on an area of sandy soil, a standard drink is 10mm of precipitation so the average depth of water in each catch cup needs to be 10mm.

If there is a sizeable variation in the depth of water captured by the various catch cups then your sprinkler system is not applying the water evenly and should be checked for design or maintenance faults. Contact a Waterwise Garden Irrigator or visit a Waterwise Irrigation Design Shop for assistance.

Once the faults have been corrected run the test again to determine how long to run the sprinklers to deliver the recommended application rate.

Search for Waterwise advice and services for more information, or to find your closest Waterwise Garden Irrigator and Waterwise Irrigation Design Shop.

If you need detailed instructions for your specific irrigation controller, look for the manual on the Watershed Water Systems website.
