The Wyndham City Stormwater Management Guideline has been established as a comprehensive framework designed to provide developers, engineers, and planners with a consistent, detailed, and clearly defined set of standards for the design, development, and implementation of stormwater infrastructure within the City of Wyndham.
The Stormwater Management Guideline serves as the Council’s formal policy document, outlining the specific requirements for drainage and stormwater management for both existing and new developments within Wyndham City.
The guideline encompasses a range of critical elements, including but not limited to:
• Essential design criteria for stormwater infrastructure
• Onsite Stormwater Detention (OSD) specifications
• Detailed submission requirements for Council approval
• Integrated Water Management (IWM) standards for small-scale developments, in alignment with Planning Scheme Clause 53.18
This comprehensive framework is designed to promote sustainable development by ensuring that all developments within Wyndham integrate stormwater drainage systems and Water Sensitive Urban Design (WSUD) solutions that adhere to best practice standards. The guideline aims to ensure that stormwater systems are developed and managed in line with the highest industry standards, comply with relevant regulatory requirements, and support the long-term sustainability goals of the local community.
All drainage design documents, including WSUD documentation, are to be submitted to the Stormwater Engineering team through the Drainage Design Submissions form. Kindly be advised that the Stormwater Engineering team will not review designs submitted directly via email. Please allow up to 10 business days for a response.
Legal Point of Discharge (LPOD)
The Legal Point of Discharge refers to the location where storm water exits a property and is authorised to discharge into Council’s drainage infrastructure, or another storm water capture provision. The Legal Point of Discharge does not refer to a physical pipeline. It refers to a location only.
To apply for legal point of discharge information, you are required to complete a Legal Point of Discharge and Council Easement information application form.
Permissible Site Discharge (PSD)
Permissible Site Discharge refers to the maximum allowable rate or volume of surface water (rainwater, stormwater, or runoff) that can be discharged from a development site into the drainage system without exceeding local drainage capacity.
This discharge rate is calculated based on factors such as the size of the site, the type of development, the permeability of the ground, and the capacity of existing drainage systems. The permissible discharge ensures that the development does not overwhelm local drainage infrastructure or contribute to downstream flooding. Before commencing your drainage design, it is strongly advised that you obtain the Permissible Site Discharge (PSD) for your site.
To request for the PSD, please contact the Stormwater Engineering team by emailing Planningdrain.submissions@wyndham.vic.gov.au
