The City of Subiaco has adopted a remote irrigation control system at 33 of its parks, reserves and streetscapes to reduce its groundwater use.

Key achievements

  • Implemented a more efficient irrigation system
  • $1,000 for new system
  • 62.9 million litres of water saved in 2012

Why we acted

"Every drop counts. Being able to remotely manage the city's irrigation systems can save up to 4550kL a night" City of Subiaco.

The City of Subiaco is committed to reducing water use at every angle and understands the importance of appropriately managing their groundwater resources.

With the strain on groundwater supplies the City of Subiaco Parks and Environment Services staff were interested in managing the irrigation systems at a more professional and efficient level.

Since staff hours are regulated to an 8 hour working day from Monday to Friday, the City wanted to be able to adjust its irrigation schedule afterhours, without needing to be ‘in the office'.

How we did it

By embracing technology, an iPad was added to the City’s Rainbird Maxicom Irrigation Central control – which runs the irrigation at 33 parks, reserves and streetscapes around the City.

By monitoring the weather forecast, staff members can log onto the central control and check the City's weather stations.

If there has been sufficient rainfall and an irrigation event is scheduled the irrigation at all parks is cancelled.

What we are doing now

The City of Subiaco continues to monitor weather events and cancel irrigation events when there has been a sufficient rain event.

The new technologies also make testing and fault resolution more efficient for Parks and Environment staff.
