We offer a wide range of rainwater sets for the garden, where the water is used for watering greenery and garden work. The selection of the size of the tank is a key issue in the design of the system. The tank is always selected on a case-by-case basis, taking into account the amount of rainfall, the size and type of catchment area capturing the rain, the efficiency of the filtration equipment. Tanks are designed to be able to store a supply for a certain number of days without rainfall. We use our capacity calculator to determine the capacity of the tank. It estimates the rainwater yield received from the catchment area, comparing the water consumption for irrigation with this estimate. More information can be found in the guide.
