A cost model for all designed facility types is now available in Stormtac database, with references and a large number of facility details, e.g. pipes, wells (drain inlets), plants (vegetation), filling materials, shafts and pumping stations. These can be cost-calculated at a general level, without regard to site-specific conditions.

Standard, minimum and maximum costs are calculated based on input data in the form of number, length, area (m2) or volume (m3). The calculation is performed directly in the database.
