Floating Treatment Wetlands Calculator
Water Quality Planning Made Simple
Rapidly size & configure Floating Treatment Wetland systems to improve stormwater quality while enhancing waterways and public spaces.
Our FTW design tool assists with preliminary planning by analysing treatment requirements and recommending an appropriate Floating Treatment Wetland configuration based on your project parameters. Generate clear reports and visual concepts to support early-stage discussions with clients, councils and project teams.
AtlanCube Calculator
Designing Modular OSD Cube Systems
Quickly design, configure and create preliminary drawings for your project’s AtlanCube underground detention system – across a full range of heigh profiles and modular configurations.
Simply enter your project location, stormwater parameters and catchment information to receive recommended designs. The calculator produces a fully visualised 3D model together with detailed engineering reports that can be downloaded, shared or revisited through your secure account.
MegaVault Calculator
High-Volume Precast OSD Design Tool
MegaVault is designed for medium to large scale assets, and our design tool provides rapid sizing and configurations for high-capacity underground stormwater detention.
Using your project location, catchment parameters and engineering specifications, the calculator analyses storage requirements and assists in designing a modular MegaVault system fit for your project. After developing your OSD solution, your projects are securely stored in your personal account, allowing you to revisit, refine and generate updated reports.
