A new wetland beside Jerrabomberra Creek in Kingston will play a key role in improving water quality in the creek and in Lake Burley Griffin.

It is one of three ACT Healthy Waterways projects in the area that will bolster the work the now established Jerrabomberra Wetlands already does – filter stormwater before it flows into the Lake and provide habitat for the growing number of native animals and birds that call the wetlands home.

The three new wetlands – at Eyre St in Kingston, Matina St in Narrabundah and off Diary Rd I Fyshwick – will remove a combined 114,000kg of nitrogen, phosphorous and suspended solids from stormwater every year.

The Eyre St wetland is one of the biggest ACT Healthy Waterways projects with a treatment area of 6000 square metres. It will draw water from Jerrabomberra Creek for treatment.

The site was previously a municipal waste site. Geotechnical and contamination investigations conducted during the design phase confirmed the likely presence of waste including gravel, concrete and steel but no hazardous materials.

However, to avoid potential leaching and contamination, the wetland will be built on an impermeable base and constructed almost entirely in fill excavated from other sites.

Start date October 2018
Construction finished March 2019+
Anticipated establishment periodTwo years from completion^
Open for public use March 2019*

+Construction may be delayed by a number of factors, including bad weather. Planting is part of the construction phase and the timing of the growing season may impact on construction timelines.
^Water plants in particular may take up to two years to become established. The length of time may vary depending on ground and weather conditions.
*Some areas of the site may remain closed to the public past this point to allow for additional planting or for plants to become established.

Design changes

Although water quality is the priority for ACT Healthy Waterways, the project team is also working to a fixed budget and timeframe.

As a result of consultation with the community and, in particular, the Jerrabomberra Woodlands and Wetlands Trust and Canberra Airport, a number of changes have been made to the original design. These include:

  • The repositioning of the wetlands away from the creek edge to protect the riparian habitat. This move also allows for the future removal of the transmission towers and cables without damaging the wetlands.
  • The reconfiguration of the wetlands to eliminate large open water areas or roosting islands that would attract large birds and increase the risk of bird strike at the nearby Canberra Airport.
  • The replacement of through pathways for pedestrians and cyclists to separate users from riparian vegetation.
  • The relocation of the pump station away from the noise-sensitive creek area.

How this project might impact you

  • Trucks will pass in and out of the area during the improvement work. Routes have been established to minimise traffic disruption and noise.
  • Any detours for traffic, walkers and cyclists will be in place and will be clearly signposted.
  • The construction site will be fenced for public safety during the preparation, construction and establishment phases of the project.

The contractor has prepared a Construction Environment Management Plan (CEMP) to detail how it will deal with flora and fauna issues.
