The paper is devoted to one of the most important problems of the mechanization of reclamation works that is the condition of reclamation systems and ways of ensuring high-quality operation of irrigation and drainage canals. The authors explain the causes of canal deformations, as well as the change in their initial project profiles. Basically the effective cross-section of drainage canals is decreasing during the operation, that results from sedimentation and siltation, which in turn affects the throughput. The authors present approximate annual amounts of canal cleaning workload, introduce various earth canal cross-sections in drainage systems and the distribution of the drainage canals specific length, depending on their purpose, per 1,000 ha of drained areas. The authors have specified the canal cleaning workload, as well as the sequence of the canals recovery operations using different machines. They also have proved the necessity of using two large groups of trucks for drainage and irrigation purposes and identified the main canal parameters determining the design of canal cleaning work equipment, and mainly, its working body, i.e. a bucket. The authors also stress the importance of dual controlling of land reclamation systems.
