| Summary: | Pachuca de Soto satisfies only 45% of the daily allowance for domestic consumption. 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. |
