Estudio de Viabilidad de un Sistema de Captación de Agua Lluvia en Guamaní – Quito

In Guamaní, to the south of Quito, there is a shortage of water and due to this problem, this investigation was proposed to consider the technical and economic viability of the design of a rainwater harvesting system. Monthly rainfall and volume of water capable to capture in an established place were analyzed. The proposed design has considered the consumption of an average family home, with four members, requiring 150 L per person. The monthly demand for a family is 18 m3 of water and the average volume captured annually in Guamaní was 6.68 m3. The maximum savings would occur in April and the minimum in July, consuming 6.10 and 17.21 m3 of potable water, respectively. The implementation cost would reach USD 460.76 and an average monthly saving of USD 115.50 would be generated, with a recovery time of four years, approximately.
