SUMMARY:

Faced with the water supply crisis, between 2016 and 2018 and the high water consumption in Brasilia, concentrated in single-family, high-income, and multi-family homes, middle-high income, a marketing opportunity was presented for the introduction of non-potable water systems as a technological instrument of urban environmental management that stimulates sustainability, quality and efficiency in water use in the built urban environment. Thus, this research aims to increase the costs and benefits involved in the use of on-drinking water building systems in buildings in the Federal District; and to examine the legal framework applicable to the implementation of public policies aimed at encouraging water conservation in buildings; and to smooth out the applicability of different existing financing models for the installation of building non-drinking water systems. A systematic review of the literature was carried out considering the prandial adaptation, costs and benefits involved, the potential of reducing the consumption of drinking water and economic, environmental and social benefits generated; survey of legal and infralegal normative acts relevant to the implementation of non-potable, federal and district water systems;; the variables obtained through the literature review were directly linked to investment decision-making by the target public regarding the implementation of a non-potable water use system, through the SWOT Matrix (FOFA). It was observed that investments in Rainwater Use Systems, SAAP in single-family homes have a payback, ranging from 2 to 14.9 years for high-income households, from 2.8 to 9.4 years for high-middle income, from 15.4 to 23.4 years for lowmiddle income and for low income 16 years to 24.7 years for return on investment. The life of the system is 30 years. Not the case of the Ash Water Reuse Systems, SRAC. The financial economic viability for the use of this system achieves a better efficiency for residence of multifamily members of medium-high income. The water savings reach 65m³/residence/year, equivalent to R$9,858.69/residence throughout the year, and economic benefits of 5.04 R$/m³ of water saved. The set of economic indicators, such as positive LPV, the rate of return lower than the cost of investment and the useful life of equipment higher than the rate of return, both in the SAAP and in the SRAC, points to economic and financial gains for residential and commercial users in relation to the substitution of the use of drinking water. The Strategic Matrix of SWOT pointed out satisfactory results related to gains, environmental, economic and social in the implementation of public policies aimed at the implementation of a system for the use of non-drinking water in homes and commerce. It was concluded that it is necessary to develop public policies directed to the public financing of 100% of the project, with an affordable interest rate, deadlines.
