Simulação da economia de água decorrente da substituição de aparelhos convencionais por economizadores no Centro de Tecnologia da Universidade Federal da Paraíba – Campus i

Abstract

Water is an essential resource for the emergence and maintenance of life on Earth. In addition, it is an indispensable factor for the development of various human activities. However, the increase in demand, non-rational use and waste make this resource become increasingly scarce in some regions of the planet. It is estimated that one-third of the world's population suffers from lack of water, and this prospect worsens when one looks to the future. Therefore, several programs were developed at the national level in order to rationalize consumption and reduce waste, as is the case of PURA, a rational water use program developed by SABESP, which in one of its proposals encourages the exchange of appliances by water-saving appliances. In this context, the present work aims to carry out a study in order to implement a system of rational use of water, from the exchange of conventional equipment by water saving equipment. This measure aims to rationalize consumption as well as reduce waste of water in the Technology Center - CT, located in Campus I of the Federal University of Paraíba. For this purpose, a water diagnosis of the Center was carried out, evaluating the typology of the hydraulic / hydrosanitary apparatus used, and the estimation of the overall water consumption of the center. Subsequently, the prognosis was carried out with and without the application of water saving devices, in order to verify their potential water savings in the mentioned center. In this way, it was possible to verify the savings in percentage and volumetric terms that the introduction of these devices in the hydraulic system of the center would result. In general, the exchange of the appliances in all the environments of the TC implies a reduction of 40.7% in water consumption, which gives 3404.36 m³ / month, an extremely considerable economy. To improve the water management of the center, another measure was proposed. Due to the lack of sectorized measurement in the university, in addition to the existence of wells also without measurement, makes it impossible to carry out studies with accurate data of consumption, this makes it essential to implement measurement sectorized by means of hydrometers or micro meters, so to know the actual consumption of water in the TC and, consequently, to allow new research and management of the institution to work with more precise data.
