Transform Your Drainage Design Productivity

A powerful end-to-end drainage design solution that enables streamlined and adaptable designs.

Flow is a hydraulic modelling package for the design and analysis of optimal, compliant and cost-effective storm and foul water drainage networks, developed for organisations looking for a robust, intuitive and complete solution.

Whether standalone (PDS) or embedded within AutoDesk environment (SmartTools), the powerful CAD interface provides a single, all-encompassing solution.

Expand Your Design Capabilities

Storm & Foul Design

Conveyance and hydraulic analysis allows engineers to ensure designs are compliant.

SuDS Design

Ensure outputs are compliant with UK specific drainage design requirements.

Standard Integration

Compatible with Autodesk, AutoCAD® and Civil 3D® or can be used standalone.

Fully BIM Compliant

Deliver the BIM outputs clients require and participate in all projects.

Compliant Design

Ensure outputs are compliant with UK specific drainage design requirements.

Live Design

Real-time design in 3D, longsection and plan allows for intuitive navigation and auditing of results.

Smart Drainage Design Starts with Causeway Flow

Empower engineers, consultants, developers and approving authorities to deliver an optimal and complaint design.

Causeway Flow drainage design and modelling software is built on the Modified Rational method for sizing conveyance systems and the state-of-the-art 1D SWMM engine for hydraulically analysing storm, SuDS or a combination of traditional and sustainable drainage systems.

Drainage Design Integrated With CAD

Utilise standalone or embed within an AutoDesk environment.

Causeway Drainage Design provides a powerful integration between Flow and either PDS or SmartTools. Changes made are dynamically updated in either module ensuring design integrity is maintained at all times. Powerful ‘round tripping’ ensures engineers spend time value engineering rather than fixing design discrepancies.

Annotation outputs, longsections, schedules and 3D BIM models can be generated automatically from the design, ensuring consistency at the click of a button.

Work Together, Win Together

Global multi-user access to all modules at any given time.

Causeway Drainage Design allows businesses to optimise licenses, offering multi-user access that enables engineers to work in different modules at the same time.

The solution can be accessed by teams both locally and globally utilising the Causeway License manager.

Trusted By The Industry

See how Causeway Flow has helped engineers, architects and local authorities transform their productivity.

  • We wanted to achieve a more seamless operation and with the software all coming from one software house, that is definitely the case.

    David Baker, Director Travis Baker
  • Being able to see the changes occur to the network as it is edited in a graphical environment helps to ensure a fault free model. Quite frankly, the software has paid for itself several times over by now.

    Chris Slade, Managing Director CGS Civils
  • Flow has made our hydraulic design process much easier thanks to its ability to use the modified rational method for sizing conveyance systems and the deploy of the SWMM engine for hydraulically analysing drainage systems.
