Sunshine Coast Council (SCC) is committed to implementing water sensitive urban design initiatives across the region to improve the quality of urban stormwater runoff and to improve the overall quality of downstream receiving waters. As part of their commitment to improving urban runoff, SCC installed a new vegetated infiltration basin at the end of Earnshaw Street on the Esplanade at Golden Beach in Caloundra in 2015. A detailed environmental assessment identified the site as the most effective location for the installation of the infiltration basin to remove pollutants from local stormwater runoff before its ultimate discharge into the Pumicestone Passage.
SCC has commissioned the SWRG to undertake a study to monitor and report on the performance of the Earnshaw Street vegetated infiltration basin. The key outcomes of the project will include quantification of external pollution loads entering the stormwater system upstream of the infiltration basin as well as a better understanding of the hydraulic and pollution treatment performance of the vegetated infiltration basin. The study is ongoing and already producing valuable research data.
