Brighton Groundwater Scheme

Also known as the 'Third Pipe' scheme, the Brighton Groundwater Scheme supplies non-drinking water to properties in Brighton for the purpose of garden irrigation.

The scheme, the first of its kind in WA, has been operating as a trial since 2006. While reducing demand on drinking water supplies, it has also helped to reduce overall water use in Brighton.

Approximately 1,150 properties in Brighton have the service available to them, allowing them to irrigate their lawns and gardens with a water source other than drinking water. 

Water Corporation is now the owner and operator of the scheme, having taken it over from the Satterley Property Group in 2015.

Winter has come to an end, and so has the Winter sprinkler switch-off

On 1 September 2018 we switched the bores back on the Brighton ‘Third Pipe’ Groundwater Scheme. Although the Winter Sprinkler Switch-Off officially came to an end on 1 September, we’ve had good winter rain and our parks and gardens have enjoyed a good soaking. Try to hold off on switching your irrigation controller back on as long as you can. Operate your system manually as needed in September and October or until you feel your garden really needs it.

To turn your irrigation on switch your irrigation controller from ‘Off’ to ‘Auto Run’. Your controller box should be located on the side of your house.

What are my watering days and times?

Your irrigation system will be programmed to operate three days a week, in line with the Department of Water and Environment garden bore user regulations.

To find out your watering days visit

If your house is an odd number your irrigation is programmed to come on between 12 midnight and 3am, on your standard watering days. If you house is an even number your irrigation is programmed to come on between 3am and 6am, on your standard watering days.

What kind of water is used?

The Brighton Groundwater Scheme will draw water from the shallow aquifer in the local area via a series of bores located in the public open space.

What can the water be used for?

The water supplied as part of the Brighton Groundwater Scheme must only be used for watering your lawn and garden through your irrigation system. All external taps will be connected to normal drinking water supplies.

Groundwater supplied through this scheme is not suitable for drinking, cooking, swimming, food preparation or bathing. 

The groundwater source meets the Department of Health's requirements for garden irrigation. We will continue to monitor the water quality, guided by the Department of Health.
