PCSWMM is excellent.
- Vancouver, BC, Canada
I just wanted to say thank you for having THE BEST customer service of any professional company that I've ever dealt with. Your friendly, personable, and client-oriented approach is a welcome change from the rest of the corporate world.

Our company has made an intentional switch from another modelling system to PCSWMM because of its accuracy and variety.
- Brampton, ON, Canada
Thank you for the excellent webinar on PCSWMM yesterday. It was very informative, and if you have a workshop which covers the more advanced features and functions you showed us yesterday, I want to know more about it! I can hardly wait to explore the software to see if I can take advantage of the features you demonstrated!

Licensing and Pricing
The table below lists prices for the 2 single-user license options and the enterprise license option (cost effective for 3 or more users). Please note that there is a separate licensing, pricing, and support system for Europe and French speaking countries, please contact us for more information.
All licenses are subscription based and can be purchased in 12 month periods only. Each license include support for unlimited model sizes (number of nodes/entities), as well as telephone and email support by professional engineers and software updates for the duration of the subscription. Updates include both major and minor releases as and when they are made available.
Single user license
The single user licenses (PCSWMM Professional and PCSWMM Professional 2D) allows for one designated individual (licensee/named-user) to use the software, and for the software to be installed on a maximum of two computers (e.g. one desktop and one laptop), for the use of the licensee only. The software license is owned by the purchasing entity (company), however the licensee within the company/organization is the designated user of the software and is the one that qualifies for technical support.
An enterprise license is granted to a company/organization/government agency and permits an unlimited number of named users at that organization to use the software. The enterprise license becomes cost effective if you have 3 or more users of the software.
CHI registers each user and provides software activation codes for those users. Additional/new users can be designated at any time by the company during the subscription period. When it is time to renew, the company can review the list of users, determine the users going forward and purchase their subscription for the next 12 months.
How does named-user subscription licensing model benefit me?
You'll see significant increases in your productivity and savings in your budget. PCSWMM's named-user subscription licensing:
- allows evaluation of the software without a substantial initial investment,
- guarantees access to the latest features and new capabilities,
- enables easier sharing of modeling projects between clients, consultants and subconsultants,
- ensures access to the software 24/7, with no fighting for time, and
- provides a simple, transparent licensing and pricing model.
Will the software continue to work if we decide not to renew the subscription?
No, PCSWMM is licensed on a subscription basis and needs to be renewed every 12 months.
How will I access my modeling projects if we do not renew the subscription?
PCSWMM is a spatial decision support system for the US EPA SWMM5 program, and maintains an official US EPA SWMM5 input file at all times. As such, you are always able to directly access your models with the free EPA SWMM5 interface (no importing or exporting required). Furthermore, your PCSWMM project data can be stored in open standard formats so you can always have direct access to your data outside of PCSWMM.
How frequently can I expect updates?
To understand the frequency and breadth of PCSWMM updates, please see the update history on the updates and downloads page.
PCSWMM licensing includes unlimited direct telephone and email support, as well as software updates, for 12 months from date of purchase. Updates include both major and minor releases as and when they are made available. Update and support subscriptions are renewed in 12 month periods by purchasing a new subscription.
USEPA SWMM support
Support for SWMM5 is provided through the free SWMM-USERS list server. This is an excellent email-based forum for questions and answers regarding model construction, computational processes, and output interpretation, as well as more theoretical topics related to urban drainage modeling. All the various authors of SWMM are active participants and there are no spam or irrelevant topics tolerated on the list. Running since 1992, the list server has hosted thousands of SWMM discussion threads and a searchable SWMM Q&A knowledgebase is archived on the CHI site for access to past topics.
CHI will also provide direct support for the US EPA SWMM5 engine through our technical support division (for simple answers) free of charge, or through our consulting division for questions requiring a more involved analysis (please call for a cost estimate). CHI is also available for professional engineering consulting work on any urban drainage modeling project.
Peer review services
CHI offers cost-effective and timely model review services. With a quick turn around time, you can gain confidence that your SWMM5 model is setup and performing reasonably for the tasks you have specified. Deliverables include a comprehensive report on the model input and results, along with a list of recommendations for further improvement. Please call 519-767-0197 or email for an estimate.
Requirements: All Versions
PCSWMM requires the Microsoft 7, Vista, XP (SP2), or 2000 operating system, with the Microsoft .NET 4.0 framework installed. In addition, it requires a minimum screen resolution of 1024x768 pixels (XGA), a minimum of 2GB of physical memory and 100MB of disk space.
Recommendations: All Versions
SWMM5 modeling and GIS analysis can be computationally demanding: PCSWMM can easily use 100% of available CPU cycles for extended periods of time and perform sustained high-speed read/write hard drive operations. As a result, there can be significant productivity benefits in utilizing a fast CPU, fast hard drive, and more system memory. The CPU should be selected for single-threaded performance as well as multi-threaded performance.
PCSWMM is optimized to leverage CPUs with 4 or more physical cores, 4 GB of available memory per instance (recommended 12 GB or more of total memory), a 3 button mouse with wheel, 2 high resolution monitors (e.g. 1920x1200 pixels or greater) and solid state hard drives.
PCSWMM can also set up a PCSWMM computational grid on a network of computers, whereby PCSWMM organizes any number of computers to work together as a single super computer for dramatically reduced run times for model calibration and scenario analysis. For this feature, an Ethernet or wireless network of computers matching the above requirements/recommendations and a Enterprise license is required.
