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 2 and 3 will be tendered at a later stage.

All relevant building components must therefore be recorded in the channel information system. In addition to the geometric characteristics of the shaft construction, the position, height, dimension, direction, slope, profile shape and material of the sewer pipes, house and industrial connections that enter and exit must also be recorded. The measurement should be carried out to a high standard, which requires a maximum level of accuracy. The results are intended to serve as a basis for detailed and exact calculations, such as those required for hydraulic verification.

Main catchment area 1, approx. 762 shaft constructions

Main catchment area 4, approx. 702 shaft structures

Main catchment area 5, approx. 932 shaft constructions

main catchment area 6, approx. 506 shaft structures
