Brighton Groundwater Scheme

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

The scheme, the first of its kind in WA, has been operating since 2006. About 1,150 properties in Brighton have the service available to irrigate their lawns and gardens with a water source other than drinking water. 

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

What are my watering days and times?

Your irrigation system is 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 draws water from the shallow aquifer in the local area via a series of bores located in public open space.

What can the water be used for?

The water supplied from the third pipe scheme must only be used for watering your lawn and garden through your irrigation system. All external taps are to 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.
