Rapid Creek Flood Mitigation

The Northern Territory Government is working towards alleviating localised flooding.  Residents living in the flood affected areas are reminded that flooding of the Rapid Creek catchment can occur when heavy rain combined with high tides causes flood water to back up into the creek and flood low-lying properties.

Marrara Detention Basin PFAS Update

The Marrara Detention Basin is part of the Rapid Creek Flood Mitigation program of works, to be constructed on the corner of McMillans Road and Henry Wrigley Drive. As a requirement of the NTEPA, due to the proximity of the site to the Rapid Creek corridor and the Marrara Fire Station, testing for the presence of Perfluoroalkyl and Polyfluoroalkyl substances (PFAS) has been undertaken on this site. The results of the testing has determined the soils within the Marrara Detention Basin site contains trace levels of PFAS which are significantly below the Health Based Guidance Values for PFAS. To view the interim results, refer to the below documents.
