SUMMARY:

Population growth and the increase in per capita consumption have caused an increase in water demand, in addition to the influence of the increase in temperature caused by climate change. This exaggerated consumption has been affecting the environment. Several studies have sought solutions to reduce demand, through water conservation actions, with the purpose of efficient use of natural resources, without harming future generations. A UN projection (2019) on population and demand suggests that consumption could be 50% higher in 2050. This fact warns of the need for studies on water conservation, using water-saving equipment, the use of rainwater and gray water reuse. The choice of alternatives will depend on a series of factors, which separate studies must be detailed for each case. The present study aimed to assess water conservation on a urban scale, using Federal District as a case study. The multicriteria tool was used due to the presence of the actors society, government, concessionary company and environment. Thus, a balanced solution was aimed for, one that attends to all the actors, known as an optimal solution. This study used the methods of water saving devices, rainwater usage and greywater usage. The data from Federal District’s administrative regions were reorganized in accordance with their sewage treatment stations, which enabled their analysis and their drainage rivers’. Besides the sewage treatment stations, the local sanitation concessionary had it’s balance studied, enabling the knowledge of the production of the profit equation in function of the water volume billed. The methods were applied according to several alternatives, in all of Federal District, in each income class, in the less and more populous centers, in the centers of greater and lesser home consumption and in the greater and lesser monthly consumptions. The greater and lesser assessment was mad according to a study of the 95% reliability interval. The comparison criteria of the alternatives were, in the society, the citizen’s investment, the will to implement a new technology and the simple payback; in the environment it was the reducing of exploration of water resources, the variation of the quality of the water body and it’s variation of framework according to CONAMA 357. In the concessionary, the profit end the savings in the operation of the sewage treatment stations were assessed; finally, in the government, the monthly income commitment of the citizen. 35 alternatives were created, being that only 10 remained after the application of the triage parameters. The preferential alternatives of this study were using the RAC in the middle to high class (alternative 10), using RAC in the middle to low class (alternative 13), and using the RAC in the areas of population over the reliability interval (alternative 22).
