What is different about water tanks & stormwater in Hobart
Hobart is one of the driest capitals in Australia, sitting in the rain shadow of Mount Wellington with only around 600 millimetres a year, but the rain is spread across the seasons rather than concentrated in one, which makes tanks genuinely useful for year-round indoor use. Tasmania’s scheme water is not expensive, so the case for a tank is more about garden supply in dry summers, independence in the outer suburbs and rural fringe, and bushfire water supply, which is a significant motivation in the hills suburbs.
Installation is shaped by Hobart’s slopes, rock and clay. Many blocks in the foothills need a cut or a stand for a level base, and the dolerite that underlies much of the city can add excavation cost. Frost in the upper suburbs affects exposed pipes and pumps.
Year-round rain
Tanks refill through the year, so indoor use for toilets and laundry works well.
Slope and rock
Hillside blocks need a cut, a stand or a smaller modular tank; dolerite adds excavation cost.
Bushfire water
