Pond - Kambah (Lake Tuggeranong Catchment)

15/2/2019 – New construction completion date is April.

31/12/2018 – Delays caused by a lack of concrete form workers in the ACT.

14/12/2018 - Civil works continue. Recent storm events had little or no impact. Footpaths are under construction.

5/11/2018 – The gross pollutant trap has been installed.

8/11/2018 – Planting will commence soon.

The new pond near the Burns Club in Kambah will be a great addition to the area, with a seated platform where visitors can take a moment to relax and enjoy the view.

Located just meters from Kambah Village Shops and within a short walk from local playing fields and three schools, the pond is expected to be popular with the local community but it will also play an important role in improving the health of Lake Tuggeranong.

Stormwater will be diverted to the pond from mains adjacent to Marconi Crescent, treated by the pond and returned to the underground stormwater system.

With a treatment area of 2,400 square metres, the pond will hold 2,800 cubic metres of water. Each year it will remove over 28,000 kilograms of nitrogen, phosphorous and suspended sediment from stormwater run-off before it flows into Village Creek which, in turn, flows into Lake Tuggeranong.

Although a number of trees will have to be removed to make way for the pond, new Casuarina Cunninghamiana will be planted, along with native dryland grasses and water plants.

The new pond will also help to mitigate occasional flooding in the area, retaining additional water that will be released following the peak.

During construction, parts of the nearby cycling and pedestrian paths will need to be closed for short periods of time. Diversions will be put in place but cyclists and walkers may have to cross access roads or wait for site traffic to pass. Everyone is urged to take care while in the area.

Start date May 2018
Construction finishedApril 2019
Anticipated establishment period Two years from open date*
Open for public useJune 2019

+Construction may be delayed by a number of factors, including bad weather.
^The establishment period may change depending on ground and weather conditions. During the establishment period, flows into and through the asset will be managed to suit the conditions and to protect and nurture the plants.
*Some areas of the site may remain closed to allow for plants to establish.

Design changes

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

During the final design phase, some changes were made to the original concept designs to accommodate services, community feedback and maximise water quality benefits.

  • Thanks to a maze of underground services, the stormwater diversion point was moved further north, closer to Marconi Crescent. This also allowed for an improved fall to the pond.
  • A feature retaining wall was added to the north to reduce the footprint of the earthworks and reduce the impact on native trees.
  • To increase the overall treatment performance of the pond, a 60m3 sediment forebay was added at the inlet.
  • A high-flow outlet was added to the southern end of the pond.
  • Initial plans proposed an existing stormwater pipe be diverted but site survey and detail design allow for the existing pipes to be retained, eliminating further disturbance of the native trees.

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.
  • Detours for walkers and cyclists will be in place and will be clearly signposted.
  • The construction site will be fenced for public safety during the entire length of the project.
  • The contractor has prepared a Construction Environment Management Plan (CEMP) to detail how it will deal with flora and fauna issues.
