Automated Stormwater System Planning and Design Software

Overview

Automate the sizing of traditional stormwater systems and BMP facilities..

xpdrainage is an automated stormwater design software program that provides comprehensive assessment of stormwater designs and is enhanced by "one-click" optimizing for all Runoff Reduction practices. Unlike many other tools and spreadsheets that assist with facility planning, xpdrainage is integrated with CAD to shorten the design time, whatever your workflow.

xpdrainage will help you to complete projects before their deadlines, present very clear and understandable reports to constituents and be more confident in your overall design because it is integrated with your current CAD drawing software.

xpswmm allows integrated analysis of flow, pollutant transport and sustainable design measures in engineered and natural systems including ponds, rivers, lakes, overland floodplains and the interaction with groundwater.



Applications for Residential Development and Sustainable Urban Stormwater Design:

  • Stormwater System Retrofits
  • On-site detention design
  • LID stormwater control systems
  • Treatment Trains
  • Water Quality volume assessments
  • Automation of the Unified Stormwater Sizing Process

Why xpdrainage?


CAD Integration

Using separate tools for your stormwater facility design (spreadsheets, hand calcs or other 3rd party tools) and your CAD layout causes several problems: a disconnect between what the tools "understand", and time loss trying to translate information from one tool to another. xpdrainage integrates your proposed stormwater design and your CAD drawing so that your stormwater system is better optimized and quickly translated back to your site schematic.

Use Natural Flowpaths

The "Deluge" feature provides a fast method of analysis for identifying overland flow patterns. This gives you the opportunity to bring stormwater management to the front of the design process by placing stormwater controls in locations that make the most sense and require the least amount of site excavation.

Clear Visualization of Design

Demonstrating system performance visually against live network data – clearly showing there is adequate space for stormwater controls on site and that the levels of your design are correct and work effectively – builds trust and confidence in results submissions. Traditional LID design using spreadsheets and hand calculations leave gaps that aren't visible until you are too far into the planning process. xpdrainage removes any guess work and allows you to see profile and plan views of your design to visualize how much space you are using and how your system is connected.

Simplified Workflow

An easy to use interface guides you through the design process with ribbon and toolbox options presenting a logical workflow, which helps to quickly move from beginner to advanced user. Built into the xpdrainage interface is its intuitive workflow navigation that guides the user through the design process, making it easy to pick up and learn. The software responds to your current action to present only valid and sensible options and guide you what to do next.

A Treatment Train Approach

Stormwater systems can be complex but they are often designed separately ignoring important effects of downstream water levels. Designing with connected stormwater controls saves time and avoids costly mistakes. Unlike traditional methods of LID design, xpdrainage allows stormwater management through a treatment train approach. EPA Best Management Practices encourage the use of measures that include multiple stormwater controls in order to limit peak discharge and to address water quality concerns.

xpdrainage enables planners, engineers, developers and hydrologists to create advanced stormwater controls:

  • Full range of storms or import rainfall events from a variety of formats
  • Lateral inflows
  • Profile views
  • Swales with and without trenches
  • User defined facilities
  • Underdrains
  • Interception and evaporation
  • Multiple rainfall methodologies (SCS, ARR, FSR, FEH)

What's New - xpdrainage 2018v1

Preliminary Pipe Sizing

Step more easily through the steps needed to complete the preliminary pipe sizing part of your stormwater design. Use this as the first step to sizing before running full analysis. Or stop here and submit your pipe sizing report for approval.

Initial Sizing Ribbon

Find all the tools for your preliminary pipe sizing in one place to save time navigating between different parts of the software.

Pipe Sizing Wizard

Step through setting up Pipe Sizing Criteria, reviewing proposed changes and producing a full Pipe Sizing Report quickly and easily.

More Pipe Sizing Options

To reduce the number of manual changes needed minimum and maximum gradients for different pipe sizes and fixed slopes have been added to the sizing options.

Pipe Sizing Report

Quickly view and output rational method pipe sizing reports in standard HEC-22 format or customizable, reusable layouts to meet local requirements.

IDF Table

Now set up multiple return periods / average recurrence interval IDF tables instead of individual rainfall collections. Use our pre-populated templates for NOAA Atlas 14, KOSTRA 2000 and KOSTRA 2010 IDF Data or create, save and re-use custom templates for your region.

Extended Preliminary Sizing Options

Setup separate preliminary sizing (rational method) and dynamic analysis options in the same catchment areas to take account of different methodologies available.

NEW Chamber Stormwater Control

Quickly layout Arch, Circular and Rectangular chambers or create and reuse custom chambers for stormwater storage. Visually see them laid out on plan with export to CAD and GIS options available.

Rational Method Cv Calculator

Using widely used tables of suggested runoff coefficients this built in calculator speeds up defining catchment characteristics. Local guidelines may differ from the calculator values and where values differ the locally recommended values should be used.

Seasonal Cv Values

Required in the UK by the Wallingford Procedure with FSR and FEH rainfall methods, summer and winter Cv values can be used to enable one simulation to run all storms required for design.

Additional Pipe Roughness

Now choose between Colebrook-White pipe roughness coefficient or Manning’s n values to suit your local guidelines and requirements.
