Conservation measures proposed are: to reuse recoverable gray water and harvest rainwater in a social interest housing to reduce the need for clean water for non-potable purposes. The volumes of necessary drinking water (167.7 L/inhab/d), reusable gray water (73 L/inhab/d) and wastewater (53.4 L/inhab/d) were quantified. The average daily rainfall (Adr = 1.28 mm) was determined for one year, from a historical record of 1991-2014. The volume of rainwater with Adr, the available roof area (A = 75 m2) and a runoff coefficient for concrete surfaces (Cr = 0.8) were estimated. The total water scarcity (WSF) footprint was determined, adding the direct (DWSF) and indirect (IWSF) water scarcity indicators. A regional water availability indicator (AWARE Annual agri) was used; direct inputs (drinking water consumption before and after using conservation measures), as well as an indirect entry (water consumed in the operation of a ¾ Hp pump). The WSF was reduced from 4.83 to 1.91 m3 equivalent, mainly through the DWSF. Pachuca de Soto satisface sólo el 45% de la dotación diaria para consumo doméstico. Se proponen medidas de conservación: reusar el agua gris recuperable y cosechar el agua de lluvia en la azotea de una vivienda de interés social para reducir la necesidad de agua limpia para fines no potables. Se cuantificaron los volúmenes de agua potable necesarios (167.7 L/h/d), de agua gris reusable (73 L/h/d) y de agua residual (53.4 L/h/d). Se determinó la precipitación promedio diaria (hpd=1.28 mm) para un año, a partir de un registro histórico de 1991-2014. Se estimó el volumen de agua de lluvia con hpd, la superficie de azotea disponible (75 m2) y un coeficiente de escurrimiento para superficies de concreto (0.8). Se determinó la huella de escasez hídrica total (HEH), sumando la huella de escasez hídrica directa (HEHD) e indirecta (HEHI). Se utilizó un indicador regional de disponibilidad de agua (AWARE Annual agri); las entradas directas (consumo de agua potable antes y después de utilizar las medidas de conservación), así como la entrada indirecta (agua consumida en la operación de una bomba de ¾ Hp). La HEH se redujo de 4.83 a 1.91 m3 equivalentes, particularmente a través de la HEHD.
