The Ćelije Dam is located in the municipality of Kruševac, built on the Rasina River near the village of Ćelije, approximately 30 km upstream from Kruševac. The construction of the dam was completed in 1978. Ćelije Dam is an earthfill dam, with a height of 51.5 m and a horizontal crest at an elevation of 285 m above sea level. The normal retention level of the dam is at 277 m above sea level. The construction of the Ćelije Dam created a reservoir with a total volume of 64 million cubic meters. To extract water from the reservoir, a cylindrical intake tower was constructed with an internal diameter of 4.6 m. The tower is 46.0 m high, with cylindrical walls that are 1.0 m thick. A visual inspection of the intake tower, conducted after extraordinary hydrological events in the second half of 2019, revealed cracks along almost the entire height of the tower. The cracks are grouped into three vertical directions around the tower, positioned approximately 120° adapt from each other. At the end of 2020, the Jaroslav Černi Water Institute initiated extensive investigative works to determine the extent of the damage to the concrete structure of the intake tower and the causes of its occurrence. The primary objective of the investigations was not only to assess the extent of the damage but also to identify the reasons for its occurrence and to predict the future behavior of the structure under operational conditions.
