Wilfred Taylor ReserveWater StorageSite InformationA 93ML capacity water storage will be constructed on the north-eastern corner of Wilfred Taylor Reserve to store harvested stormwater for reuse.
The storage is a critical element of the Christie Creek upgrade project. It provides the necessary storage to enable the harvest, treatment and supply of up to 850ML of stormwater every year, which would otherwise be lost to sea.
The storage will be constructed using ‘cut-to-fill’ with a maximum cut of 7.6m and a maximum fill of 6.8m above existing surface levels – giving an overall depth of approximately 8.2m. It will be lined with a plastic liner for improved water quality, to maintain internal embankment walls and to help retain water. It will have a overflow weir and channel will be constructed on the north-eastern edge of the storage.
Recreation and landscape improvements include the construction of a 2.5m wide linear trail between States and Panalatinga Roads, new tree plantings around the base of the storage, grassing and groundcover planting.
