Within the Sustainable Development Goals. Agenda 2030 of the United Nations, SDG No. 6, aims to ensure the availability of water and its sustainable management and sanitation for all.
This is a challenge not only for governments, but also for the private sector, which must seek and promote strategies within the sector where the companies are located to develop sustainable management that does not sacrifice the available use of water for the regions and communities where they operate.
This management should not only seek a positive impact on water savings within the companies, but also contribute to the conservation of tributaries or water sources such as wells or others to ensure access to water.
For the Waya Hotel, as part of its LEED Certification in sustainability, it initiated a management inside the hotel that has always sought efficiency in water consumption.
In terms of potable water consumption efficiency, the hotel achieves an average savings of 61% overall with respect to the LEED baseline. One of the strategies used to achieve large savings in water consumption is the use of high-efficiency sanitary fixtures. Another strategy is the use of treated wastewater from the hotel’s own water treatment plant, which supplies non-potable uses such as irrigation, toilets, and cleaning. Last month the water savings from this WWTP was 50%.
In addition, treated wastewater is used to irrigate the 1500 m2 of plants that require it, thus avoiding the use of potable water, and the irrigation system is also efficient by drip irrigation. As a result, 100% of potable water use is saved.
Another important point is that the landscape is landscaped with native plants with low water consumption, and the irrigation system is efficient, saving about 90% of treated water consumption.
Externally, the Ranchería River is the most important river artery in the department of La Guajira, and although the hotel does not intervene directly in the river, it indirectly contributes to its conservation by planting trees and making good use of waste disposal in its operation to reduce any possibility of contamination. This river originates in the La Horqueta hill at more than 3,000 meters above sea level in the Sierra Nevada de Santa Marta and flows into the Caribbean Sea in La Guajira. The Ranchería River flows through the municipalities of Distracción, Fonseca, crosses Barrancas and reaches Hatonuevo and Albania, where the Waya Hotel is located. After this route it turns to the northwest and delivers its waters through Riohacha, the capital city, in a 150 km journey.
In the upper part of La Guajira, where most of the indigenous communities are located, there are no rivers, due to the Monte de Oca geological fault, which divides the Middle and Upper Guajira, and is the cause of the Ranchería River flowing westward, preventing the north of the department from having larger tributaries. For this reason most of the Wayuu Indians use the Jaguey, a rainwater reservoir, which they accumulate to have fresh water while the summer passes. These Jagueyes are permanently built or rehabilitated by organizations, private companies or administrations to guarantee water to the communities.
