WERT helps you to execute a quantity and cost calculation as well as an asset valuation for sewer networks according to DWA-A 133. To do this you can use the data created with GraPS, HYKAS or KAREL. For the asset valuation you can access the cost of production or, if not known, have it automatically determined using the cost module. The depreciation is carried out either linearly or in the course specified by the production costs or the replacement time. In addition to the depreciation, the imputed interest is also shown.
