| Summary: | In this study, centralized and decentralized
wastewater reuse alternatives were compared in terms of water saving potential
and costs for a touristic case study area in Antalya, Turkey. The results of
decentralized reuse revealed that the maximum water saving of a hotel is
limited with either amount of wastewater generated or ratio of irrigated
landscape area to bed number. The
breakpoint for the case study area is estimated as 50 m2/bed. As a
result, in hotels where the ratio of irrigated area is less than 50 m2/bed,
wastewater reuse may not be cost effective. In case of centralized
wastewater reuse, supply and demand is balanced and as a result 60% more water
saving may be achieved for the case study area. Furthermore, investment and
operation cost of centralized reuse are considerably low and the price of
reclaimed water is lower than price of service water. The average unit price of
reclaimed water used as irrigation water was found to be 1.29 €/m3
in decentralized reuse, while the unit price was found to be 0.35 €/m3
in centralized reuse; which brings forth an internal rate of return by 20% and
a 5-year payback period. |
