Demo Versions

We do not distinguish between demo and full versions; they are both the same program. The application will simply run in evaluation mode if you do not have a valid license. You can purchase a license at any time, which will unlock the software. Feel free to download any of the above applications and try them out for as long as you like.

When Wadiso and Sewsan are running in evaluation mode, all their modules are enabled, but modelling is restricted to 50 pipes.

When Albion is running in evaluation mode, drawings and GIS data cannot be saved.

If you would like to obtain a temporary evaluation license that frees you from these limits, please contact us via support@gls.co.za.
