We are improving capacity in our stormwater network to make it safer for Canberrans and more friendly for the environment. Standards change over time, but through implementation of a progressive program, the Territory will enhance the network and address problem areas by constructing infrastructure to current standards. Ranging from major works to localised issues, rolling upgrades are being planned around Canberra to manage water movements more effectively.
Through a variety of means, Roads ACT, within TCCS, maintains the urban stormwater network around the Territory. Assets managed to achieve successful water management include sumps, stormwater pipes, stormwater channels, various kerbs, water quality pond embankments, cut off drains, retarding basins, gross pollutant traps, dams and weirs.
While essential for a growing city, urban development significantly increases the area of impervious surfaces from which rainfall quickly runs off. These surfaces include roofs of buildings, paved areas, roads and car parks, and to a lesser extent, grassed and garden areas. During significant storm events, overland flow is exacerbated when the stormwater network is at capacity. Through active investigations around future land use with consideration for known trapped low points, a network of drains, channels and floodways have been designed and built around the ACT to manage water in excess of the pipe capacity and direct this increased flow of stormwater to storage facilities, be them bodies of water and/or retarding basins. Complementing this process, ACT Healthy Waterways will help to improve water quality as it travels through various catchments around the Territory. Planned improvements to the stormwater network coupled with existing facilities will have tangible benefits to our network, including:
Indirectly, the stormwater network also provides several other benefits to the residents of the ACT. These include enhancing the urban landscape and providing recreational opportunities through the use of lakes and ponds.
The suburbs currently identified and funded for upgrades are:
Funding Value: $19.061 million was provided over four years in the 2019-20 ACT Budget for upgrades at Page and Weetangera, Fyshwick South and Waramanga. Existing funding of $2.65 million from the 2018-19 budget used to initiate investigations in Page and Weetangera and Fyshwick South will complement this funding. Additionally, $1.56 million was provided in the 2019-20 ACT Budget for minor urban improvements the Calwell, Narrabundah, Gordon, Duffy, Nicholls and O’Connor.
