Project Description:

According to the order of a national sports federation, an inventory data collection and an evidence preservation procedure were carried out on existing drainage systems. One of the main aspects was the technical inspection of the connections of grease separators and integrated cisterns with regard to proper construction and dimensioning. System components such as large dimensioned infiltration pits were measured and verified with regard to the respective infiltration performance.

The preservation of evidence and documentation included the re-measurement of the entire drainage network (rainwater and wastewater), the revision of existing planning documents, the description of defects and necessary corrective measures as well as the examination of the construction costs incurred in the course of the installation. Aspects of licensing law were agreed with the responsible drainage authority.
