Announcing Causeway Flow

Next-Generation Drainage Design Software

 Built on state-of-the-art technology, Flow allows engineers, developers, and approving authorities to deliver optimal and UK-compliant storm water, foul water and sustainable drainage systems (SuDS) design as well as individual structures like soakaways with newfound confidence.

Flow enables cost-effective, compliant, and comprehensive drainage system design without the trade-offs. Flow is an end-to-end - comprehensive drainage design and modelling software built on the Modified rational method for sizing any conveyance systems and the state-of-the-art 1D SWMM engine for hydraulically analysing any storm drainage system.



A New Way to Design

  • Pre-Development Runoff Calculation
    Covers UK-specific greenfield and brownfield runoff
    calculation methods
  • Automatic Sizing of The Pipe Network
    Improves workflows with less time spent defining networks
    in a specific order
  • Specifiy Flow Controls
    Specify multiple controls in a manhole without creating a
    single depth / flow relationship 
  • Specify Storage or Infiltration Structure
    With unique FTP technology that mimics natural flows
    through storage or infiltrating structures 
  • Powerful Simulations for Confident Design
    Analyse multiple storm durations for multiple return period
    in a single simulation
  • 3D Drainage Network Design Visualisation
    Stay in control with real-time animations of water levels in longsection, graph, and 3D views
  • Reduce Risk with Live Design and Simulations
     View live results simulataneously in longsection, graph,
    plan graphic and 3D form.
  • Design Reviews for Assured Approvals
    Audit designs based on UK-specific criteria for confidence
    in final design submission approval
