Biogardens process and treat gray and soapy water and allows its reutilization.
Grey water comes from the laundry, showers, hand basins, dishwashing and other domestic uses. In Hotel DiuWak´s case, seven shallow long ditches were dug, river stones placed at each end, rocks in the middle and submerged lilies and heliconias. Amazingly, the roots of these plants fulfill a natural chemical process which purifies the water, which then drains into the local river without contamination.
Initially built in the mid 2000´s, the project was so successful, the National University of Costa Rica studied its results for three years, its Chemistry department analyzing samples monthly. Overall, the water´s purity tested at 80-90%, and does not pollute the environment. The Hotel DiuWak is the only hotel in Costa Rica that purifies 100% of its black, grey and soapy waters through its 7 artificial biogardens.
