Irrigation systems are the biggest water guzzler in the home!
Reticulation can use up to 130 litres of water per minute so, if you have pop-up sprinklers at 4 stations, and run them twice a week for 10 minutes on each station, that uses around 5,200 litres.
Tip: Shorten your irrigation run times by just 2 minutes per station and see how much you can save!
MP rotators are generally the most efficient types of sprinkler, with pop up/fixed spray sprinklers using the most.

A broken sprinkler head can waste up to 40 litres per minute, so test your irrigation system for any possible leaks. You can check for leaks yourself following these steps. Make sure you test on your allocated watering day either before 9am or after 6pm.
- Set each station to 2 minutes.
- Take a reading of your water meter before running the first station – you can use our monitoring card to take readings.
- Write down the reading again once the 2 minutes has run through, and calculate how much water was used.
- Repeat this for all stations. If the reading for each station is around the same an irrigation leak is probably not causing an increase in your water use.
- If one or more of the stations recorded a significantly higher amount of water passing through, then you probably have a leak somewhere.
This test will only be accurate if each station has the same type and number of sprinklers.
New lawn or gardens
You may also be using more water through extra reticulation or watering if you have put in a new garden or lawn.
You can apply for a watering exemption to get your new lawn or garden established – but this only means you are exempt from watering breaches and not for the cost of the water use.

Set your irrigation controller to the weather conditions and the time of year. Find your automatic controller manual on the Watershed Water Systems website.
