Propuesta e implementación de un proyecto piloto para el desarrollo de un sistema de riego para la huerta, con una fuente alternativa del recurso hídrico, en el colegio Luis Carlos Galán, comuna cuatro de Cazucá

Abstract

This document contains the information for the implementation of an automated irrigation system with a source of rainwater, in order to facilitate the care of the school garden in times of recess. Taking into account the sequential stages for the implementation of the project, which are: the agronomic design in which it delimits the area of ​​the crop, the water demand and type of species to be harvested are calculated, then in the hydraulic design it is taken into it counts the losses of load generated by the accessories and pipes, avoiding variations in the flow of the drippers; finally in the Arduino design the programming and calibration of the sensors is developed, for the activation of the irrigation automatically. On the other hand, based on the information collected by the IDEAM of daily precipitation over a period of time from 1975 to 2015, maps (IDW) of Cazucá's multi-annual monthly precipitation were constructed, using the interpolation method with weighted inverse distance , to identify the amount of rainwater available in the different months, in this way and following the methodology of CEPIS [1], the construction of a rainwater collection, storage and distribution system that allows the irrigation of the garden school and this in turn is not affected in times of school break or temporary cut of the public network service, facilitating their care. On the other hand, being a didactic method for teaching topics such as natural resources, environmental care and teamwork. Due to the aforementioned, this project is associated with initial costs and benefits for its implementation. As a result, a school garden of easy maintenance and care was obtained, thanks to the integration of a rainwater harvesting system, which covered the entire water demand of the vegetables and an automated irrigation system, which allowed the irrigation of the garden autonomously; Finally, the school garden was built by the students of Luis Carlos Galán School, generating in them teamwork and knowledge development regarding: agriculture, water use, use of recycled materials, for the development of the project.
