Abstract This paper explores the possibility of harvesting rainwater in a Testing Tank used to test scale models of boats and ships in Jahu College of Technology, São Paulo State. We considered local rainfall data, the coverage area for catchment and the demand for water. Water demand was estimated for cleaning, filtering and evaporation processes in the Testing Tank. The dimensions of the reservoir were calculated according to the methodologies described in the NBR 15527, which prescribes the requirements for the use of roofs in urban areas for the catchment of rainwater for non-potable purposes. The volume of the reservoir selected enabled the best use of rainwater and resulted in a better reduction of water demand on the public supply system. It was chosen as the best alternative after comparative analysis considering the local restrictions and the risk of non-compliance.
