SUMMARY:

Water conservation has become an essential component of water resource management in the current uncertain water availability scenario. A detailed understanding of water end-uses in health care facilities paves the way for greater accuracy in evaluating different water conservation strategies, sizing building systems, forecasting urban demand and, consequently, in creating public policies aimed at water conservation. However, it is essential to know the implementation costs, environmental and financial benefits of each strategy in order to implement water conservation programs. It is the responsibility of the Secretary of Health to technically and financially support the municipalities, elaborate actions, and implement public management policies that can favor the reduction of the exploitation of water resources. Based on these premises, the objective of this research was to identify feasible solutions in terms of costs and environmental and financial benefits promoted by the implementation of water conservation strategies in healthcare facilities. The method outlined made use of different water consumption auditing techniques to generate indicators of building consumption, sectoral consumption, water end-uses, financial indicators, and a forecast model of urban water demand by type of healthcare facility. The statistically analyzed data were essential for the composition of representative models and identification of environmental and financial benefits, at the building and urban scale, with the use of water-saving equipment, rainwater harvesting systems and greywater reuse systems. The feasible solutions were evaluated by type of establishment and guidelines for strategic planning were determined. We obtained indicators of building water consumption for basic health units, UBS (31.74 l/p/d and 3.80 l/m²/d), emergency care units, UPA (33.63 l/p/d, 6.70 l/m²/d and 411.56 l/bed/d) and hospitals (79.56 l/p/d; 9.40 l/m²/d and 671.51 l/bed/d). The toilet bowls presented the highest consumption by end use, resulting in indicators for UBS (15.9 l/p/d), UPA (14 l/p/d) and hospital (12.4 l/p/d). Results identified that the use of water-saving equipment in basic health units, emergency care units, and rainwater harvesting systems for hospitals presented themselves as viable solutions for the conservation of drinking water and reduction of the exploitation of water resources. The potential for water consumption reduction can reach 74% in UBS, 28% in UPA and 24% in hospitals. Water savings at the building scale can reach 402 m³/year (UBS), 755 m³/year (UPA) and 9,899 m³/year (hospital). At the urban scale, 95,003 m³/year, 7,039 m³/year, and 267,712 m³/year, respectively. The financial savings obtained at the building scale can reach R$ 2,588 (R$/m³/year) (UBS), R$ 4,805 (R$/m³/year) (UPA) and R$ 62,828 (R$/m³/year) (hospital). On the urban scale, R$ 611,707 (R$/m³/year), R$ 44,823 (R$/m³/year) and 1,699,178 (R$/m³/year), respectively. Actions to promote water conservation in health care facilities in the Federal District will generate environmental benefits of 369,754 m³/year and financial benefits of R$ 2,355,708.90/year. Thus, the guidelines proposed for the implementation of viable strategies can be used by the Federal District's Health Secretariat with a view to sustainable development and preservation of water resources.
