This paper illustrates the current situation of the CA1 adduction canal, the possible technical solutions, the technical comparison between two waterproofing variants, the presentation of the rehabilitation works, as well as the main technological stages of the waterproofing of the canal in the Babadag area, county of Babadag. Tulcea. The two solutions that will be analysed are the following: the first solution consists in restoring the CA1 channel to its original dimensions and waterproofing it using the following technical solution: waterproofing using 235 g/m2 geotextile + 0.75 mm HDPE geomembrane + C20/25, 8 cm concrete slabs, reinforced with welded mesh, and the second solution is restoring the CA1 channel to its original dimensions and waterproofing it using the following technical solution: waterproofing using EPDM geomembrane reinforced with polyester mesh. The extension and rehabilitation of the irrigation infrastructure in Romania is expected to have a significant economic impact on the economic viability of farms, increase the competitiveness of farmers, but also support the agricultural sector to be able to face the long-term challenges of climate change, in particular those related to drought, as well as to ensure food stability and security in adverse climatic conditions. In the project we aimed to rehabilitate the hydrotechnical works of an irrigation plot in the Babadag area, we analysed the situation of the whole, we proposed general valid solutions for the condition of the hydrotechnical works and we customised to the situation and technical solutions suitable for the CA1 canal. We have analysed its transport capacity, finding that, if it is decolmated, it meets the flow conditions required for operation, but with a higher water level at the required flow rate.
