Technical Support

Welcome to the PCSWMM.NET technical support section. Descriptions of the resources here are given below.

Getting started exercise

There is a downloadable getting started exercise that steps new users of PCSWMM.NET through the process of creating a simple hydrologic and hydraulic model with water quality. We have provided both US and SI unit versions of this exercise.

Product updates

Ensure you have downloaded and installed the latest version of PCSWMM.NET from our product updates web page.

Technical support knowledge base

Search for answers to commonly asked questions on our knowledge base.

US EPA SWMM specific questions

Questions relating to the SWMM engine should be directed to the SWMM-USERS list server. If you are not yet a member of this list, please sign up - it is free and an incredibly valuable resource. Before posting your question though, please check the searchable SWMM Q&A database for past topics. Also please be aware that PCSWMM.NET interface-specific questions should not be sent to the list.

For SWMM engine questions which haven't been resolved through the knowledge base or SWMM-USERS list server, CHI provides direct technical support for the US EPA SWMM5 engine to current licensees 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 modeling project.

Contacting CHI

After consulting the available information listed above, licensees of current software may request assistance by contacting us directly (see table below). Questions regarding computer runs should be emailed with relevant input data files attached.

CHI offers unlimited support on the PCSWMM.NET interface to active licensees. Licensees are named in our licensee database at the time the license is issued or re-assigned. Please ensure you are using the latest version of the software (see product updates above).
