CUS 3D Manhole Survey & Inspection

We offer CUS Manhole Surveying and Inspection Services with our patented CUS surveying system (pat. no. 397.432).

Advantages of CUS

Automatic on-site checks on diameter, material, slope, direction, profile during survey. This reduces mistakes and postprocessing works compared to manual inspection methods. Automatic on-site checks of sewage network topology. Automatic generation of a precise as built drawing for the complete sewer network, as a result of the CUS 3D-survey. Data recording for large manholes, special structures or polygonal and oval manholes is analog to standard manholes which guarantees a consistent integration into any CAD and GIS system. TV inspection results - e.g. german ATV-DVWK tokens PA and PE - can be allocated with their accurate layout positions. TV inspection results can be compared with real sewer pipe lengths. Sewer pipe requirements can be checked accurately, e.g. +- 25 cm accuracy according to German ATV-DVWK for inspection events like connection or branch pieces. CUS survey is independent from flow and weather conditions. Surveying during full manhole activity is possible. Deposits or sediments on pipe inverts do not falsify results. Many worksite safety requirements are not required. With CUS surveying and inspection system the inspection personnel does not need to step into manholes. No risk for inspection personnel. CUS guarantees highest constant quality for the results. CUS affords simple export of all digital inspection data to any common sewage database system without post-processing works. Digital Pictures (JPEG, GIF, TIFF) and Video Documentation (MPEG1, MPEG4, DivX) of the manhole's condition are an indispensable help for establishment of maintenance or rehabilitation programs.
