Abstract

Water is the most valuable asset of the planet, is essential for any form of life, however the man uses irrationally. Currently the world is facing a serious water crisis worsens with the disorderly use of water, the water sources that supply the cities have become scarce due to increasing population and pollution released to them. This negative scenario results in a search for alternative and sustainable solutions for water conservation, and one of the alternatives is the use of rainwater, which consists of mechanisms for their capture and storage in order to take advantage of it for non-potable purposes. This work consists of a project for the implementation of a recovery system of rainwater for a commercial multi-family building. For to development of the project were used pluviometric data of the last eleven years of the region, and a general analysis of the building through photos and measurements, in order to know the available space. After analyzing the data, based on the acquired theory, it was possible to verify that the Alfredo Fressato Building has a catchment area of 421,40 m² and is capable of generating an average monthly volume of rainwater 48,573.37 liters, is sufficient for the estimated demand of 29,776.00 liters for non-potable purposes. In order to supply non-potable water to the building, it would be necessary to install an upper reservoir of 2000.00 liters capable of supplying two days of use, another lower reservoir with a capacity of 52210.00 liters sufficient to have water during periods of drought and installation of a lifting system, preferably with a solar- powered pump, guaranteeing a more sustainable system. After all the calculations and the final design of the rainwater harvesting system, it was possible to estimate the cost of implementing this project.
