45 years of innovation and improvement in the stormwater industry
Evolving Australia's favourite hydrology method for the needs of the 21st century.
The next generation of XPRAFTS is available in InfoWorks ICM with RAFTS hydrology
XPRAFTS has served the Australian industry well for over 45 years
Development of XPRAFTS written for Windows started in the mid 1990's with the first version commercially released in 2000. Twenty years on and many of the software coding tools we used then are now obsolete or unsupported.
The InfoWorks ICM interface was built with tomorrow in mind.
It uses a modern, scalable and efficient architecture to increase project velocity with an underlying database that can make automated and widespread data changes. This, in turn, delivers more efficient and higher quality engineering outcomes and better integration with 3rd party systems. InfoWorks ICM is a significantly refined product using the latest available technology to drive user efficiency and engineering performance. We have built features specifically designed to provide users with a high-value upgrade path from a fragmented hydrological XPRAFTS workflow, to a more efficient and outcome-driven integrated tool, InfoWorks ICM (Integrated Catchment Management).
With the release of InfoWorks ICM v9.5 in November 2018, Innovyze delivered the next generation of the RAFTS routing method into the world's #1 tool for hydrological, stormwater and flood modelling analysis. The next release of InfoWorks ICM 2021.1 is scheduled for November 2020, when we will no longer sell new licenses of XPRAFTS. We will continue to provide support for existing XPRAFTS users, with valid annual maintenance contracts, until December 31, 2021. Upgrading is simple and can be carried out by a local account manager which you can reach here.

Read these frequently asked questions below
Can I continue to use XPRAFTS?
Absolutely! We are not terminating any valid XPRAFTS licenses, it's just that we are no longer selling new XPRAFTS licenses. Full support and maintenance for existing valid license holders will continue for another 12 months up until the 31st December 2021, and even after that, existing XPRAFTS users can continue to use their XPRAFTS software, but will no longer receive any updates or support from Innovyze.
What about XPSWMM and XPSTORM?
This information relates to XPRAFTS only. XPSTORM and XPSWMM licences continue to be supported and we are looking forward to the new features coming in the 2020.1 release due out soon.
Is anyone using InfoWorks ICM?
Yes, ICM is not new at all. Since its RAFTS release in 2018, both local government and engineering consulting firms have been able to quickly adopt ICM and the feedback has been extremely positive, particularly regarding the enriched user experience, higher productivity and powerful data management with full version control and unlimited UNDO.
Is there any loss of functionality when moving from XPRAFTS to InfoWorks ICM?
All the standard features of the XPRAFTS application can be done in the new InfoWorks ICM software as well. In fact, ICM contains several significant enhancements and new features. In short, you will still enjoy all the comprehensive features of XPRAFTS with a more powerful interface and a richer user experience.
How much does it cost to move from XPRAFTS to InfoWorks ICM?
This will depend on the 'size' of your existing license of XPRAFTS and if your organization has an active InfoCare plan. All current InfoCare customers using XPRAFTS can upgrade to ICM for only the difference in price between the two products (that is, maintained customers will receive full credit for your XPRAFTS licence investment, no matter when they were acquired).
Can I keep my existing copy of XPRAFTS while I get up-to-speed with the new InfoWorks ICM software?
Yes, those upgrading to ICM can retain their existing XPRAFTS license(s). This is so that existing XPRAFTS-based project work can be completed while getting up to speed with the new InfoWorks ICM software. However, InfoCare will be valid on ICM only and no support for the XPRAFTS license(s) will be provided.
What's the difference between InfoWorks ICM and ICMOne?
ICMOne incorporates all the powerful modelling and analysis features and capabilities of InfoWorks ICM, except is limited to one user editing and solving on a single PC at a time and is provided at a lower-entry subscription model.
How do I convert my old XPRAFTS models to ICM models?
It's a quick and simple process that requires just a few clicks of the mouse. A special migration file can be produced by exporting the model as an XPX file from within the XPRAFTS interface. This can then be imported directly into ICM using the toolbar Network > Import > Model.
Will my results be the same?
RAFTS in InfoWorks ICM uses the same non-linear storage routing equation, S = B x Q ^ n as XPRAFTS and XPSWMM (referred to Laurenson method). Internal result comparisons between all 3 products showed <1% difference. These minor differences are a result of ICM's more robust iteration scheme providing more accurate results.
If my XPRAFTS model is old, do I need to update it into the latest version of XPRAFTS before converting it to InfoWorks ICM format?
If the XPRAFTS database is from an old version of XPRAFTS, we suggest that you update it to a more recent edition of XPRAFTS before you migrate to ICM.
If I decide to keep using my existing XPRAFTS license for now, will it work on future editions of the Windows Operating System?
We cannot guarantee that. Looking forward 3 to 5 years, it is not difficult to foresee a situation where Microsoft drops support for 32-bit applications in one of its forthcoming Operating System updates. Indeed Mac and Linux Operating systems have already dropped most 32-bit support. In addition, some Windows security updates have in the past inadvertently locked out some of our simulation engines from running and required us to release a security patches/fixes to resolve the engine failures. XPRAFTS is a pure 32-bit software application and will not be re-engineered into a 64-bit program. If a future edition of Windows ceases supporting 32-bit applications, XPRAFTS will no longer run on that OS platform. There is a parallel to draw on; when Windows 7 came out in 2009, Microsoft ceased its support of 16-bit applications. That was the final straw for XP-AQUALM and XP-CULVERT (other legacy products), which contained 16-bit code in the User Interfaces and supplementary tools. InfoWorks ICM has been a 64-bit application since its first release in 2010, so it will not be affected by any move away from a 32-bit architecture by Microsoft in the years to come.
Are there any obvious technical limitations to using XPRAFTS in the future?
It's generally accepted that demands on memory usage will inevitably increase as time goes on. The 32-bit Operating System can only manage a maximum of 4GB of RAM, and 32-bit software applications can typically only use up to 3GB of that RAM. This restriction applies even if you run a 32-bit application on a 64-bit Operating System. By comparison, 64-bit applications can access much larger amounts of memory (practically you would only be limited by the amount available on your PC). Users are already finding that trying to simulate very large XPRAFTS models with the incredible volume of data in ARR2019 can result in 'out of memory' errors and compounding reductions in simulation and model performance given the 32-bit architecture. Moving to a 64-bit application effectively removes this barrier.
The same applies for the databases that underpin XPRAFTS. In XPRAFTS, there are many raw database size and card limits that have been artificially worked around over the years to be able to access more RAM and write more tables, but these 'hacks' and shortcuts will invariably impact performance. In 1995, no one dreamed this would ever be a problem. Less than 10 years later, it was already becoming an issue for many models. There is no theoretical size limit to InfoWorks ICM as it uses a world-class relational database architecture. So, you are limited only by the size of the storage device on which the database is stored.
All the standard features in XPRAFTS can be done in InfoWorks ICM and more.
The new release of RAFTS in ICM honours 45yrs of innovation and improvement in the stormwater industry, evolving Australia's favourite hydrology method for the needs of the 21st century.
