Streamlined Stormwater and Drainage Design

A visual platform for the design, analysis & review of stormwater controls, XPDrainage takes a treatment train approach to walk you through the design process.

Create Advanced Stormwater Controls

Planners, engineers, developers, and hydrologists know that designing stormwater controls is complex. Simplified workflows in XPDrainage guide you through the entire stormwater design process, implementing a treatment train approach.

Achieve More with Your Design Time

Achieve More with Your Design Time

XPDrainage integrates with CAD and GIS platforms to shorten the design time. So you can complete projects ahead of deadlines and present clear, understandable designs and reports for review.

Speedier Reviews and Approvals

Clear design visualization in XPDrainage shows that your design levels are correct and will work. As XPDrainage provides reports in the required format, less post-processing work is needed, making approvals faster and easier.

Design Sustainable Drainage

Design Sustainable Drainage

XPDrainage enables sustainable and traditional drainage design from a single package. Sustainable drainage plans are quick to assemble, easy to communicate and thoroughly reviewable. ‘One-click’ optimization for Runoff Reduction makes sizing green infrastructure systems easy.

What you can do with XPDrainage

  • Get Clear Visualized Designs

    Purpose built to provide a visual, approachable platform, XPDrainage ensures your designs are easier and faster to review by planning and development engineers.

    Get Clear Visualized Designs
  • Integrate with CAD and GIS

    Pull design and layout information directly from AutoCAD or your favorite GIS platform and push design modifications back with a click of a button. Build up your design using existing data or drag and drop the stormwater controls on your plan view.

    Integrate with CAD and GIS
  • Use Natural Flowpaths

    A 'deluge' feature gives you a fast way to identify and analyze overland flow. Then you can place your stormwater controls in locations that make most sense, and you save on site excavation works.

    Use Natural Flowpaths
  • Treatment Train Analysis

    XPDrainage walks you through the stormwater design process using a ‘treatment train’ approach. Linking stormwater controls maximizes the effectiveness of traditional pipe design with Green Infrastructure practices and follows EPA Best Management Practice.

    Treatment Train Analysis
  • Flow Controls and Conveyance

    XPDrainage allows you to integrate flow control devices and conveyance calculations into drainage design. You can be confident that your design will achieve the required greenfield runoff rates.

    Flow Controls and Conveyance
  • Calculate Storage and Runoff Volumes

    The automated sizing capability in XPDrainage returns the most compact, lowest cost solution. The storage estimate and runoff reduction water quality volume calculators in XPDrainage present a quick initial guide before you create your detailed stormwater control design. Runoff in catchments is calculated using SCS, SBUH, Time Area, Time of Concentration or Laurenson runoff methods.

    Calculate Storage and Runoff Volumes
  • Advanced System Validation

    With XPDrainage you can quickly check potential level inconsistencies or input errors that could impact your model if left unfixed, before you proceed with your model.

    Advanced System Validation
  • Expert Training and Support

    Comprehensive tutorials, videos, help, blogs and other resources get you up and running in hours. Our engineers are on hand for any tricky problems. And you can reach us by phone, email or via our online support portal.
