The paper analyzes failures of retention reservoirs of waste water located at the premises of an important power-engineering facility. Waste water retention reservoirs have been broken during their existence. The character and extent of the failures have caused serious concern to the operator about the loss of tightness of the retention reservoirs at which the entire operation would be seriously compromised. For the design of effective and functional remediation measures, it was necessary to clearly define the extent and the causes of the failures. The failure of waste water retention reservoirs was caused by underestimating the interaction between the structure and the rock environment. The primary cause of the failure was the negative effect of the buoyancy effect of the water on the impermeable bottom of the reservoirs caused by the flow of subsurface waters to the construction of the tanks fitted into the morphological muld. The secondary causes of the failure were the shortcomings of the geological survey, in particular the underestimation of the non-standard behavior of soils - swelling of clay soils in the basement of the reservoir in contact with water. Other causes were project errors such as inappropriate selection of construction materials - heavy panel paving slopes on smooth sealing foil and realization errors.
