Stormwater & flooding
Stormwater & flooding services
At Diversi Consulting, we provide a comprehensive range of stormwater and flooding solutions tailored to enhance the functionality and sustainability of water management systems. Our services include pit & pipe drainage design to optimise water flow, along with analysis of existing systems to assess performance and identify improvement areas. We specialise in creek & channel hydraulics to manage watercourses, ensuring flood mitigation and erosion control.
We also offer stormwater detention systems designed to manage peak flows and reduce flood risks. Our flood mapping & studies provide in-depth flood risk assessments, while integrated water management plans address water use and sustainability. Additionally, we deliver water harvesting & reuse solutions and incorporate water sensitive urban design (WSUD) with MUSIC Modelling to ensure compliance and optimise stormwater management.

Pit & Pipe Drainage Design
Diversi Consulting designs pit and pipe networks that ensure reliable stormwater management while meeting regulatory requirements.
Our approach focuses on efficiency, sustainability, and long-term performance. By tailoring each design to site conditions and future development needs, we create solutions that support resilient and well-functioning communities. This includes optimising flow capacity, integrating water-sensitive urban design principles, and ensuring seamless connections to existing infrastructure for both greenfield and brownfield subdivisions.
Analysis of Existing Systems
Understanding the performance of existing stormwater systems is critical for identifying issues and planning improvements. Diversi Consulting conducts detailed analyses to evaluate capacity, identify inefficiencies, and recommend actionable solutions.
Using advanced diagnostic tools, we provide a clear picture of your system’s current condition. Our insights help clients make informed decisions to optimise performance, extend the system’s lifespan, and reduce the risk of flooding or failure.
Creek & Channel Hydraulics
Specialising in creek and channel hydraulic design and analysis to manage water flow effectively and mitigate flood risks, our services focus on erosion control, flow capacity, and environmental impacts, ensuring sustainable outcomes for waterways and adjacent developments.
By applying advanced hydraulic modelling techniques, we create designs that balance functionality with ecological considerations. Whether natural or engineered, our solutions protect communities while preserving environmental integrity.
Stormwater Modelling
Accurate stormwater modelling is essential for predicting system performance and planning for extreme weather events. Diversi Consulting utilises industry-leading software, including HECRAS and TUFLOW, to simulate stormwater behaviour and assess the impact of various scenarios.
Our modelling services support informed decision-making by providing precise data on flow paths, capacity, and flood risks. This ensures our clients can implement robust stormwater management strategies that are resilient and reliable.
Stormwater Detention Systems
Stormwater detention systems are crucial for managing peak flows and reducing downstream flooding. Diversi Consulting designs efficient detention solutions, including basins, tanks, and underground systems, tailored to the specific needs of each project.
Our approach prioritises compliance and functionality, ensuring systems effectively mitigate flood risks while integrating seamlessly with surrounding infrastructure. With our expertise, clients can manage stormwater volumes confidently and responsibly.
Flood Mapping & Flood Studies
Flood mapping and studies are essential tools for understanding flood risks and developing mitigation strategies. Diversi Consulting provides detailed assessments that identify flood-prone areas and quantify potential impacts under various scenarios.
Our flood studies combine hydrological data with advanced modelling techniques to inform resilient planning and design. This empowers clients to minimise flood risks, comply with regulations, and protect communities effectively.
Integrated Water Management Plans
Integrated water management (IWM) plans are a strategic approach to managing water resources across urban and natural systems. Diversi Consulting develops comprehensive IWM plans that coordinate water supply, stormwater, and wastewater management to achieve practical, efficient outcomes.
Our plans focus on resource efficiency and resilience, delivering innovative solutions that meet both community and operational objectives. By integrating diverse water systems, we provide strategies that optimise water use and ensure long-term reliability.
Water Harvesting & Reuse
Offering efficient water harvesting and reuse solutions that reduce reliance on traditional water sources, our team design systems that capture, treat, and reuse stormwater and greywater for irrigation, industrial, or other non-potable applications.
By applying advanced technologies and industry best practices, we create cost-effective systems that deliver both economic and operational benefits. Our solutions provide reliable and practical water management across both urban and rural environments.
Water Sensitive Urban Design (WSUD) & MUSIC Modelling
Water Sensitive Urban Design (WSUD) integrates stormwater management into urban landscapes to improve functionality and water quality. Diversi Consulting designs practical WSUD solutions, including rain gardens, bio-retention systems, and constructed wetlands, to effectively manage water treatment and retention.
Using MUSIC modelling software, we optimise these designs for performance and regulatory compliance. Our approach ensures efficient stormwater management, reducing the impact of urban runoff and enhancing the overall effectiveness of water management systems.
