Stormwater and waterways

Water is an integral part of the culture and geography of Hobart, from the mountain water supply catchment to the Derwent Estuary boating community.

The City of Hobart owns over 339 kilometres of stormwater mains and more than 550 other forms of stormwater assets (including kerb and gutters and dish drains). We also maintain the rivulets and creeks that run for over 60 kilometres in length. 

We clean and repair the pipes, pits and drains and upgrade or replace them as necessary.

Hobart is more than 200 years old and the installation of stormwater infrastructure is relatively recent, so some parts of the city don’t have any or limited infrastructure, which can lead to properties and roads being subject to inundation or water-related nuisances. 

Many properties discharge stormwater from roofs onto the ground or into sewer pipes. This may cause problems for neighbouring properties and the sewer network. Stormwater in the sewer network may cause sewer overflows onto roads and private properties during heavy rainfall. Where properties discharge onto the ground, downhill properties can be flooded. 

There is also increasing public awareness of the natural values of waterways and that they should not be contaminated by human activity. As such, any new or existing developments need to be reviewed to take into account the health of waterways and the River Derwent. 

The City of Hobart’s ongoing Master Drainage Schemes, Catchment Management Plans and Asset Management Plans are guided by our Stormwater Strategy
