Shaft survey in the city area of Fürth as a basis for constructing/updating the sewer database and extrapolation of the 6 main catchment areas.

The main catchment areas 1 and 6 have already been put out to tender, the main catchment areas 2 and 3 will be put out to tender at a later date.

All relevant building components must therefore be recorded in the sewer information system. In addition to the geometrical characteristics of the shaft structure, the location, height, dimension, direction, slope, profile shape and material of the incoming and outgoing ducts, house and industrial connections must also be recorded. The measurement should be carried out to a high standard, which requires a maximum level of accuracy. The results should serve as a basis for detailed and exact calculations, such as those required for hydraulic verification.

Main catchment area 4, approx. 702 shaft structures

Main catchment area 5, approx. 932 shaft constructions
