Brickworks Lake irrigation

The City is installing two water tanks around Brickworks Lake reserve to irrigate surrounding areas.

The City has turned off the pump that previously extracted irrigation water from the lake as a precaution due to the presence of cyanobacteria.

A temporary tank will be operational later this month, with a permanent tank to be constructed next to existing bore infrastructure. The permanent tank will be operational from late January 2025 and the temporary tank then removed. Both tanks will allow irrigation to be supplied directly from the bore without connection to Brickworks Lake, eliminating any risk associated with cyanobacteria.

The City will manually water the reserve in the coming weeks using water trucks until the temporary tank is operational. Any yellowing of turf is expected to recover when the temporary tank is in operation.

The temporary tank location (November to January) is shown in blue, with the permanent tank location shown in orange.

Temporary pipework will be visible for connecting the temporary tank to existing irrigation infrastructure. Vehicles will be required to access the reserve during construction of the tanks, with appropriate traffic management in place.

Two trees will be removed to make way for the permanent tank. These trees have been assessed by an arborist as poor quality and will be replaced with 10 Marri trees (Corymbia calophylla) in the 2025 winter planting season. Marri trees have been chosen due to their suitability as a foraging plant for Carnaby's black cockatoo.
