| Sumario: |
Urban areas are currently experiencing rapid growth, which brings with it increases in the
population, the expansion of impervious surfaces, and an overall jump in the environmental and
hydrological impact. To mitigate such an impact, different strategies proposed to tackle this problem
often vary; for example, stormwater tanks, the reuse of wastewater and grey water, the installation
of equipment to reduce water consumption, and education-based approaches. Consequently, this
article presents the simulation and evaluation of implementing infrastructure options (stormwater
harvesting, reuse of industrial waters, water-saving technology in residential sectors, and reuse of
water from washing machines) for managing urban water in two urban catchments (Fucha and
Tunjuelo) in Bogotá, Colombia, over three periods: baseline, 10 years, and 20 years. The simulation
was performed using the software Urban Volume Quality (UVQ) and revealed a possible reduction
in drinking water consumption of up to 47% for the Fucha Catchment and 40% for the Tunjuelo
Catchment; with respect to wastewater, the reduction was up to 20% for the Fucha Catchment and
25% for the Tunjuelo Catchment. Lastly, two scenarios were evaluated in terms of potential savings
related to water supply and sewage fees. The implementation of strategies 3 and 6 insofar as these
two strategies impacted the hydric resources. Therefore, there would be a significant reduction in
contaminant loads and notable economic benefits attributable to implementing these strategies. |
