Offsite Stormwater Treatment Project
PBPL is leading Queensland’s first scientifically-based and assessed offsite stormwater treatment project in the Lockyer Valley.
PBPL worked closely with a range of partners to implement the project, including the Queensland Government, Healthy Land and Water, Lockyer Valley Regional Council, and Mulgowie Farming Company.
To date PBPL has invested $1million dollars to rehabilitate and stabilise 1.7km of Laidley Creek. Works delivered include bank re-profiling, the planting and maintenance of 9,000 native plants and the installation of 4 cross-bed grade control structures. The works also include a major research component with scientists using innovative techniques to identify and monitor the sources of sediment pollution.
To date, rehabilitation of this upper catchment area has delivered significant environmental benefits including:
the prevention of 8,500 tonnes of sediment – approximately 445 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.

Port of Brisbane Stormwater Management
Stormwater Management fact sheet
Development at the Port
Developers at the Port need to comply with the Port of Brisbane Technical Guidelines. These guidelines require developers to manage and treat stormwater. Qualifying developers have the opportunity to partially meet stormwater quality requirements by investing into the Port’s offsite program at a rate of $30,000 per hectare. PBPL tracks development at the Port that is utilising offsite investment. The below tables summarises the investments made in Laidley Creek and the area of port development ‘treated offsite’.
Table 1: This table summarises the investment made by the Port of Brisbane offsite and the amount of land at the port that has utilised the investment.
