The objective of this study was to design and size a drip-irrigated arboretum in the Djarmaya Plain. To achieve this, a topographic survey and the use of hydraulic formulations were used to design and size the drip irrigation system. Plant requirements were estimated based on data recorded by meteorological stations in the city of N\'Djamena and the use of CropWat software. The results show that 7,346,025 CFA francs are required to develop one hectare of arboretum, for a total cost of 27,547,580 CFA francs. Topographic studies show that the site is relatively flat, although it has some low-lying areas (ponds) and large mounds. The elevations are between 290 and 297.50 m in the general leveling system of Chad. This result, in addition to the high temperatures recorded in the area causing a high need for water, trees are major indicators of the choice of drip irrigation which aims to save water.
