Get your drainage systems under control with card_1: from the initial survey and the management of existing sewer networks right through to planning, calculating and designing future networks.

Drainage-related project work is fully incorporated within the card_1 system, ensuring access to all project data all the time, without any tiresome media breaks or redundancy.

The card_1 sewer components make light work of any civil engineering tasks, allowing you to work quickly, effectively and target-oriented:

• Data capture using any common tacheometers, semi-automated on-screen digitization of raster images.
• Hydrological calculations according to time coefficient methods, RAS-Ew, DS 836 as well as EN 752 and ATV-A 118 including up to 999 rainfalls, 250,000 reaches or 10,000 special structures (stormwater tanks, backwater sewers, inverted syphons, pumps, weirs) per sewer network.
• A hydrodynamic calculation method using model rainfalls and long-term simulations combined with the determination of submerged areas and flood curves at all critical points.
• Hydrological sewer profiles to suit your individual needs. Integration of the sewers into road profiles in compliance with RE, also independently of hydrological calculations.
• Sewer base maps for all planning phases, for either new designs or redesigns - flexible in both content and scale, and based on the current data. By optimizing the positioning of the annotations prior to completion, editing is kept to a minimum.
• Utilization diagrams as well as information on other crossing or parallel utility systems.
• Finished plans and drawings according to RAS-Ew and DIN 2425 with all symbols and plan details conforming to the relevant guidelines.
• Interfaces to all common sewer applications via the ISYBAU interface.
• Volumetric calculations, calculation according to REB, digital terrain model.

Many medium-sized to large road and sewer planning offices as well as local authorities are currently putting the card_1 sewer components to good use.
