Stormwater and urban waterways
Water is an integral part of the culture and geography of Hobart, from Kunanyi / Mt Wellington to the Derwent Estuary.
Rainfall that lands on roofs, roads and other formed surfaces becomes stormwater runoff.
We are responsible for managing stormwater runoff so that it does not cause a flood risk to the community or degrade our natural waterways.
Flood modelling allows you to check whether your property is in a potential flood risk area. Find more information and links to the flood maps on the flood risk and maps page.
The City of Hobart owns over 350 kilometres of stormwater pipes and maintains more than 60 kilometres of waterways and creeks. You can view a map of the City's stormwater infrastructure. These are managed in line with our Stormwater System Management Plan.
What is not stormwater?
Stormwater doesn't include water from a number of other sources. These can also cause issues for ratepayers and the general public, such as:
- Potable water: Drinking water provided by TasWater
- Recycled water: Non-potable water provided for farming use by TasWater
- Effluent: Sewerage taken by TasWater and moved through the sewer network using a combination of gravity and pressure pipes. Sewerage usually has an odour and some cloudiness
- Groundwater: The water in the soil below the surface of the ground, which can rise and pool at the surface after heavy rainfall. We are not responsible for groundwater as it can't be collected by our drainage network
- Surface water/overland sheet flow: Water which naturally flows across natural ground and has not been concentrated by a drain, surface channel, subsoil drain, or pipe. This often occurs at the fringes of the city where properties back on to natural bushland. Surface water/overland sheet flow is not regulated by Tasmanian law.
Request for a stormwater service connection
If your property does not have a connection into the City of Hobart's public stormwater system, you may need to connect your private stormwater to the public system.
Most properties are able to connect to the City's stormwater system. Connecting to the system allows for sufficient drainage to lessen soakage issues and the risk of flooding.
We complete this connection. Our staff are trained to make sure no damage occurs to your property or the public system from the new connection.
If you would like to request a stormwater connection to your property, please complete the online form. Please note, the connection is at your cost.
Report a problem or fault
