The locations and details of the water quality treatment devices are shown on
engineering drawings at Appendix A.

Water Quality analysis has been developed in accordance with Noosa
Council, State Planning Policy July 2017 (SPP) and the Queensland Water
Quality Objectives (2009).



Queensland Water Quality Objectives (2009) have been adopted which
recommend the following minimum reductions in mean annual pollutant
loads leaving a development site compared to the developed unmitigated
case:

• 80% reduction in Total Suspended Solid Load;
• 65% reduction in Total Phosphorous Load;
• 45% reduction in Total Nitrogen Load;
• 90% reduction in Gross Pollutant Load.

Quality MUSIC modelling of the proposed treatment train has been
undertaken generally in accordance with Water by Design’s - MUSIC Modelling
Guidelines, Version 1.0-2010.
