Which Perth suburbs can have a garden Bore.
As can be seen on the map above only half the metropolitan area is suitable for a garden bore. There are various reasons for this outlined below.
- the salinity level means the water is unsuitable for garden irrigation
- the area is close to the ocean or a river are vulnerable to drawing salt water into the aquifer through bore use (e.g. the Cottesloe Peninsula)
- the area is close to conservation wetlands and other important groundwater dependent ecosystems, which could be adversely affected by bore use
- the supply may be unreliable due to the soil type (e.g. Guildford Clay)
- the area has a thin superficial aquifer underlain by a confined aquifer (e.g. the Leederville aquifer), and there may be inadvertent use or waste of the confined aquifer and the potential transfer of groundwater between aquifers. A licence is required to construct a bore and pump water from confined aquifers.
- there is potential for acid sulphate soils to be exposed to the air and increase groundwater acidity
the area is over allocated to existing users, and further development of garden bores could present a sustainability risk to the groundwater
