Technology is being presented as a way to save water. This technology comes at a price though. An economical analysis is made based on the operational costs and the investment costs. The application of water saving technology has to be economically feasible for the grower otherwise they will never implement it. Technologies used in this paper are the application of soilless culture and the closed greenhouse. The economical evaluation showed that the application of soilless culture is more profitable then the production in the soil in a pad and fan greenhouse. The investment costs of soilless culture are relatively low and the production increase is high. The closed greenhouse becomes most profitable when the price of tomato is higher than 0.75 Euro/kg.
