The following systems are analysed:

• Surface infiltration
• Swale infiltration
• Pipe infiltration
• French drain infiltration
• Shaft infiltration
• Certain combinations of the above systems

Capabilities:

• Analysis using rainfall intensity tables
  from the KOSTRA atlas
• Draft design also using Reinhold's rainfall series'
• Import of the rainfall intensity data
  determined using the KOSTRA atlas
  via a file or via the Windows clipboard
• Combination of infiltration systems
  compliant with DWA-A 138
  (e.g. swale-pipe infiltration)
• Combination of infiltration systems
  compliant with DWA-A 138 with paved areas (e.g. paving with swale)
• Analysis of infiltration systems for a variety of frequencies (recurrence intervals)
• Calculation of draining times for given
  infiltration types
• User-defined output sheet
• Print or copy screen sections, e.g. for
  transfer to a word processor
• Integrated Mini-CAD system for additional annotation of graphics
