This study evaluated the potential of water reuse in a social and cultural center, proposing
solutions for the reduction of potable water consumption and testing the technical feasibility of
four water reuse solutions. One of the solutions only suggests the replacement and/or the
modification of the equipment, whilst the remaining solutions point out for the use of rainwater
for supplying the cleaning water cisterns with variation of the volume.
Any of the solutions can be implemented and would lead to a considerable reduction of the
water consumption and the water service cost. However, the use of rainwater to supply flushing
cisterns entails very high investment costs compared to the savings achieved, making it
unviable for regions of the country with lower water prices.
In a short time period, the solution with the fastest return investment is also the one with the
lowest investment costs. However, in a long time period the greatest savings are achieved by
combining rainwater harvesting with the installation of more efficient equipment for water
consumption.
Therefore, in areas with lower water billing prices, the most viable investment it seems to be
the adoption of high water efficiency equipment’s. In areas where the billing reaches higher
values, it is economically feasible to invest in a rainwater supply system, preferably in
conjunction with the use of equipment with good water efficiency.info:eu-repo/semantics/publishedVersio
