Water use efficiency in the hotel sector of Barbados

Barbados is water stressed, with water production close to its renewable freshwater resources. The hotel sector uses far more water than the general population (756 vs. 240 L/cap-d); water savings there would improve the overall water balance. No comprehensive analysis exists for water use by the Barbados hotel industry; this study addresses the gap. Data were collected from the Barbados Water Authority and from onsite surveys; consumption patterns were compared with international studies which had established environmentally acceptable benchmarks. The water use efficiency of Barbadian hotels was also studied as a function of oinfluential variableso: unit water consumption was somewhat correlated with the number of rooms, average room rate, property size and number of employees. The lack of success in reducing hotels' water consumption is tied to the fact that water bills represent less than 5% of their annual expenses. A model for unit water consumption was derived using two influential variables: the annual number of guest nights and the number of employees. Ways of fostering sound water practices include promotion among guests of the need to save water, schemes to promote the financial benefits of water conservation by relating unit water pricing to total consumption and awareness-raising among hotel managers.
