The dam on the Kuhschnappelbach is an earthfill dam with an inclined inner seal that serves as a flood protection facility and service water reservoir and is categorised as dam class 2 in accordance with DIN 19700-11. IGSE is the owner of the dam on the Kuhschnappelbach in St. Egidien. The total reservoir capacity is 109,000 m³ and the planned flood retention area (HWR) is 15,000 m³. Due to the small HWR in relation to the operating space, it is not categorised as a flood retention basin in accordance with DIN 19700-12.
Engineering services are to be provided for the in-depth inspection of the reservoir. The basis for this includes the requirements of DIN 19700 Dams - Parts 10, 11 and 12 (2004-07) and the DWA bulletin 514 Safety Report on Dams Guidelines (draft October 2023). Accordingly, the static, geological, hydrological and hydraulic design bases as well as the operational specifications and the monitoring concept must be reviewed, i.e. all aspects that have a direct influence on the safety status of the dam.
It is therefore necessary to check whether the generally recognised engineering rules and the requirements derived from them, e.g. for construction materials, verifications and monitoring, are complied with for the dam. All available documents, measured values and operating experience must be consulted for this purpose. As a result of the review, it may be necessary to prepare up-to-date expert reports (hydrological, geological, meteorological or seismological reports) or verifications (freeboard, retention, structural safety verifications).
