Stormwater Quality Management

Stormwater Quality Management Plan for Mackay (SWQMP)

Stormwater Quality Management Plan for Mackay (SWQMP) has been prepared to establish the framework “to manage stormwater quality in urban waterways in a way that maintains or enhances the state of balance among environmental, social and economic interests within the community”.

Stormwater Quality Objectives

To support the delivery of the stormwater quality objectives through the development approval process, council developed guidelines for the use of the industry standard predictive modelling software: Model for Urban Stormwater Conceptualisation (MUSIC).

A series of development scenarios in accordance with Mackay MUSIC Guidelines were tested and treatment performance curves were developed. These curves were used as a basis for assessment of stormwater quality objectives. Proposed stormwater quality objectives for the Mackay Region are as follows:

• 75% reduction in Total Suspended Solids (TSS)
• 60% reduction in Total Phosphorous (TP)
• 40% reduction in Total Nitrogen (TN)
• 90% reduction in Gross Pollutants
