The construction of an infiltration basin at Earnshaw Street, Golden Beach provides an opportunity to protect Pumicestone Passage from the impacts of stormwater discharging off the local catchment.
The installation of an infiltration basin at Golden Beach will treat diverted stormwater from the Earnshaw Street catchment before it is discharged to Pumicestone passage, providing the opportunity to significantly reduce waterway pollution from this area.
Recently completed work includes:
- construction of an infiltration basin
- installation of diversion pipework
- planting of carefully selected tube stock
- installation of safety fencing.
This particular site was chosen at Golden Beach because it resulted in the least amount of lost grassed foreshore area possible. The dune stabilisation offered by this project also improves the recreational opportunity on the beach. Alternate locations along Golden Beach were considered but eliminated through the design process when elements such as existing pipe levels and tidal effects were taken into account.
Stormwater from the local catchment is diverted into the basin. The water will infiltrate into the sandy soils of the basin while the plants will absorb nutrients in the stormwater. The basin will remain dry most of the time and is not considered a health and safety risk for the community. Fencing has been installed on the western (road) side of the basin to prevent entry from the pathways and the basin is not expected to produce an odour.
Experienced environmental engineers and landscape architects designed the basin and surrounding landscape to ensure it fits well into the environment, park and coastal pathway.

The Pumicestone Passage and Catchment Action Plan 2013-16 lists Golden Beach as a committed site for this important council project. The Pumicestone Passage waterway has high environmental values, with many plant and animal species and is listed under the Convention on Wetlands of International Importance as an important site for migratory birds and it also supports diverse wildlife including turtles, dugong in southern areas, fish, crabs, oysters and juvenile prawns.
