The present work is a project for water supply and partial drainage of vineyard covering an area of 17.13 ha, located in the village Rayanovtsi, municipality Belogradchik in northwest Bulgaria. The aim is to provide the water quantities needed to supply drip irrigation system of the vineyard. It was designed and constructed a system for partial subsoil pipe drainage for discharging of excess groundwater, causing waterlogging of part of the terrain. Collected drainage water is important as an additional source, providing certain autonomy in the water supplying of the object. Performance of the tasks of this project is limited to applying a complex of technical-meliorative and hydromeliorative activities aiming to improve the drainage conditions in the non-drained part of the vineyard and to provide the necessary water amounts for the irrigation. In this paper are compared theoretical water balance calculations with the actual results from the first year of operation of the installation.
