Abstract
The purpose of this study is to show that, given the global water crisis, it is possible to find alternatives to reuse gray water. A gray water source may be an alternative for use in irrigation in grain crops, among other applications. This feasibility analysis was carried out for two years. The solution promotes the efficient use of water in an existing vertical building, based on the physical and social aspects of the building, adopting the rational use of water, and considering the reuse of laundry gray water for garden irrigation and cleaning of the common area. This model was used for a full-scale building, medium to high standard, vertical, condominium regime. The study found that the implementation of the measures studied may generate volume savings equivalent to the consumption of 30 families annually. To increase sustainability on a global scale it is essential to implement new water reuse projects, and to promote wise water management in buildings.
Highlights
Rational use of water is required both in the management of large river basins and in the management of small water supply systems.Urban growth in their expansion areas requires minimal infrastructure services in four areas of sanitation; the slowness in the implementation of sanitation systems is deteriorating waterways closer to the cities
Based on the premise that it becomes necessary for society and the government to promote actions aimed at rational use of water, this work illustrates and motivates the adoption of rational water use and encourages policies that generate benefits to society
This study goals to investigate the variations of irrigated agriculture indicators in Asia Oceania, Europe, and Americas from 1962 to 2011
Summary
Rational use of water is required both in the management of large river basins and in the management of small water supply systems. Urban growth in their expansion areas requires minimal infrastructure services in four areas of sanitation (water supply, sanitation, drainage, and solid waste); the slowness in the implementation of sanitation systems is deteriorating waterways closer to the cities. This fact could lead to scarcity of water resources and increased treatment costs. Regions that efficiently use water are able to provide a better quality of life to the local society
