Upper Boggywell Creek, which formerly flowed through the Gannons Park site prior to the installation of a large stormwater culvert, will be partially reinstated in lower Gannons Park. Reinstating the creek along with additional stormwater treatment (ponds, wetlands, swales and bioretention systems) will improve water quality of the stormwater entering the Georges River and will also provide a water resource for future harvesting and treatment to irrigate the upper Gannons Park sporting fields.

How does this work?

Stormwater will be diverted from an underground pipe to a reinstated creek. The water will flow through wetlands, swales and bioretention systems where it will be treated to remove pollutants. Ponds will store water for future reuse onsite and for irrigating the playing fields at upper Gannons Park.
 

What are the benefits of the design?

Reinstatement of the creek and installation of the swales, wetlands, ponds and bioretention systems will improve the local environment by increasing biodiversity, improving the quality of stormwater entering the Georges River, save potable water and provide more opportunities to enjoy the park through the associated landscaping. A new and more accessible path will link Upper and Lower Gannons Park. 

Once fully complete, the scheme will provide 26 million litres each year for harvesting, reducing potable water use. In terms of water quality, the scheme will remove 16,000 kg of sediment, 22 kg of phosphorus and 131 kg of nitrogen every year from flows entering the Georges River.
 

When can i expect these upgrades?

Stage 1 works were completed in 2018. Stage 2 works are underway and is now due to be completed in September 2020 due to wet weather delays.
