Data on the technical condition of drainage collectors of reclamation systems made of asbestos-cement and reinforced concrete pipes of large diameter (0.3–0.6 m) with a service area of 87–94 hectares have been given. Collectors were examined after 7 and 47 years of their operation, the condition of the inner surface of the pipes, the amount of siltation and the reasons for it have been determined. The low quality of construction has been revealed, during which the displacement of pipe joints and their poor sealing have been allowed. However, the studied collectors are operable even with the existing condition. Therefore, it is possible to use large-diameter polymer pipes with sealed connections at reconstruction facilities instead of separate open channels.
