Análise dos consumos de água em obras da construção civil

Abstract

As it is a non-renewable resource and of paramount importance for the survival of the world population, everyone must take care of water with more zeal. It is valid to take measures that make a construction more economical, in terms of water consumption, even if this requires additional control of the construction processes. These measures are important for the environment and can bring substantial savings in water use by the enterprise during the construction phase. Water represents one of the most important components in the production of concrete and mortar, in the humidification of soils and in the compaction of landfills and is also used in the work of washing forms, cooling and curing concrete, and in cleaning machines and tools. In civil construction, therefore, the use of water goes beyond the physiological needs of the workers and increases, mainly, in the performance of activities aimed at the execution of services. From the studies carried out by Barboza (2008), analyzing the use of water, in three different civil construction works, in the city of Maringá-PR, the analysis and comparison of the different consumptions occurred. With regard to the management of works, Pessarello (2008) and Araújo (2009) recommend water saving measures at the construction sites.
