To reduce the amount of discharge water, the quality of the output water is decisive. Rainwater contains no ballast salts and costs are lower than for groundwater. In the context of the ADLO demo project 'Growing without discharge water in greenhouse horticulture', we therefore developed a model that allows you as a grower to easily calculate the size of rainwater basin you need to fill a certain percentage of your starting water with rainwater. The model asks you about the crop, the area of greenhouse and outbuildings and the dimensions of the rainwater basin. Behind it, it takes into account the precipitation data from the KMI for the last 30 years, the weekly water consumption for the crop in question and the losses caused by initial wetting and evaporation of precipitation water on the greenhouse roof, overflowing of the greenhouse rafters during heavy precipitation and evaporation in the basin. The model assumes a classic horticultural company where the water is only used in the greenhouse. For now, only a rectangular basin can be calculated.
