STORM & WSUD Assessments for Smarter Water Management

Torple offers Water Sensitive Urban Design (WSUD) Report to ensure your project meets council water-sensitive design requirements, demonstrating effective stormwater management for compliance and sustainability. In Victoria, WSUD reports are often referred to as STORM reports named after the STORM Calculator tool.

Our Approach

Practical, Integrated Water Management Solutions

A WSUD report—also known as a STORM report—is an essential document for projects aiming to achieve Water Sensitive Urban Design (WSUD) compliance and effective stormwater management. We collaborate with architects, Designers, and developers to deliver WSUD Report (STORM Report) that aligns with council expectations and sustainability goals. Our team simplifies the process, ensuring your design incorporates effective stormwater strategies from the outset. 

Provides general site details, including hard surfaces (e.g., roofs, paved areas) and soft surfaces (e.g., landscaping). Accurate data is essential for designing effective stormwater treatments. 

An executive summary outlining the project’s WSUD and stormwater objectives, such as rainwater tanks, infiltration systems, or detention basins.

Details proposed stormwater treatments with site plan illustrations, including type, capacity, location, and connections to hard surfaces.

Outlines guidelines for ongoing maintenance to ensure efficient operation, including cleaning schedules, inspections, and operational best practices.

Includes site plans, STORM calculator outputs, and MUSIC modelling results to verify treatment effectiveness and compliance with local council requirements.

Understanding STORM & WSU

Smarter Water Design for a Sustainable Future

A WSUD report—commonly called a STORM report in Victoria—is a council-adopted approach to promote sustainable water use and manage stormwater runoff effectively. WSUD reports are essential for sustainable urban development, helping ensure that new developments minimise environmental impact while enhancing water efficiency. 

The application and scope of WSUD requirements vary depending on the type of development and local council regulations. Typically, all residential and commercial developments—except in some cases for single dwellings or minor alterations—must submit a WSUD report or stormwater management statement when applying for a building permit. 

WSUD reports help developers comply with Australian water-sensitive urban design standards while creating environmentally responsible and sustainable developments. 

Key Objectives of a WSUD Report or STORM Report Protecting Water and Promoting Sustainability

The primary objectives of a WSUD report include:

  • Protecting ecosystems and water-sensitive environments

  • Encouraging water reuse within the development

  • Reducing stormwater runoff, flood risks and supporting green stormwater management solutions, such as raingardens, wetlands, and bio-retention systems.
  • Improving stormwater quality through sedimentation, filtration, and treatment
  • Restoring natural waterways and waterbeds

  • Promoting the use of filtered wastewater for non-potable purposes

FAQ

Have some Questions

A WSUD (Water Sensitive Urban Design) report, commonly called a STORM report in Victoria, is a council-required document that ensures new developments manage stormwater effectively, promote sustainable water use, and comply with local environmental standards. 

WSUD/STORM reports are typically required for residential developments with 3 or more dwellings, commercial projects, mixed-use developments, and sites in environmentally sensitive zones. Requirements may vary based on local council regulations. 

The report includes general site details, stormwater treatment plans, WSUD commitments, maintenance guidelines, supporting documents like site plans and STORM calculator outputs, and actionable recommendations for sustainable water management. 

WSUD reports promote water reuse, reduce stormwater runoff, improve water quality through filtration and treatment, restore natural waterways, and support green stormwater solutions such as raingardens, wetlands, and bio-retention systems. 

Our process includes an initial consultation, site review and data collection, assessment and reporting using STORM tools and WSUD principles, followed by submission support and any necessary revisions to meet council approval.

Yes, WSUD/STORM reports provide maintenance guidelines, including cleaning schedules, inspections, and operational best practices, to ensure stormwater treatments continue to function effectively over time. 

Torple collaborate with architects, designers, and developers to align the report with council expectations, using accurate site data, industry-standard tools like STORM and MUSIC, and actionable recommendations to achieve approval and compliance.
