The article presents data on the survey of beamed ponds and dams on the beams of Berestova, Shcherbakova and Gruzskoe on the territory of the Rostov region and establishes their poor condition. To use the ponds as a water source for irrigation of surrounding agricultural land, it is necessary to conduct repairing work on water ponds. In the article, to improve the efficiency of irrigation on local runoff, delayed in beams of low head dams we have proposed an improved design of fastenings (coatings) of upland slopes of groundwater retaining structures, including the ranks of absorbing wave elements. We have recommended symmetric and asymmetric placement of the semi-oval and tapered parts. We have also proposed a simple solution of wave absorbing elements as parts of a triangular shape (isosceles and equilateral), mutual accommodation of which also forms a water conveyance channels for mutual collision of threads

In the article, the way of sealing of cracks and filtra-tion courses is offered, with a soil compound from soil cement with an additive, the list of construction operations on extension of a body of a dam over the designed marks is also offered

In the article we have proposed the technology of repair works using improved soil mixture sifting the rubble and ash using soil mixture installation and without it. For prevention of occurrence of defects and damages we have offered an antifiltration device in the form of screen and core from compacted obliquely pulled layers of impermeable soil

The article presents the technology of repairing un-derground structures with levees soil mixture bran and ash. We have also set out technological opera-tions to rebuild the dam
