Offsite Stormwater

Port of Brisbane Pty Ltd (PBPL) is leading Queensland’s first scientifically-based and assessed offsite stormwater treatment project in the Lockyer Valley. 

In 2016, PBPL provided $500,000 to fund the pilot project and following its success, committed an additional $500,000 to continue the project, taking our total commitment to $1 million over three years.

We worked closely with a range of partners to implement the offsite stormwater project including the Queensland Government, Healthy Land and Water, and Mulgowie Farming Company.

In total, the work has rehabilitated approximately 950m of degraded creek bank along Laidley Creek – adjoining some of the region’s most valuable horticultural land. It also involved re-planting approximately 4000 native trees and grasses and constructing two cross-bed grade control structures. 

The project also included a major research component with scientists using innovative techniques to identify the sources of sediment pollution at the Port.

The results

To date, rehabilitation of this upper catchment area has delivered significant environmental benefits including:

  • the prevention of 4,800 tonnes of sediment – approximately 250 truckloads of dirt – from entering Laidley Creek, anticipated each year

  • significant water quality improvements to the Brisbane River and Moreton Bay

  • improved flora and fauna habitats at the site

  • increased agricultural productivity at the site by improving land security and providing protection from future flood events.

The existing site will be maintained for three years.
