Any changes to the technical components of the drainage network and the efficient removal of excess water are highly dependent on both the manner in which the prepared surfaces are used, either in bulk or in individual plots, and their use class. This paper tackles the operational behaviour of the drainage network after 40 years of use on arable land. Our research has revealed that the banks of the higher rank ditches have eroded and their bottom has clogged, which has reduced their flow section by 15% on the average. This diminution does not hinder the capture, flow and discharge of collected waters. The absence of any maintenance works has allowed woody and hygrophilous vegetation to grow, which reduces the water flow rate, increases alluvial sediments and clogs the discharges holes of the drains. In the lower rank ditches on the drained surfaces, the 0.40-0.70 m thick alluvial sediments have led to the complete plugging of the discharge holes of the plastic drains. The use of land as individual plots has accelerated the decommissioning of lower rank ditches, which served only for draining the land and which were then released for agricultural use.
