According to our analysis and the prior definition for water scarce area, the company doesn't have plants in areas with water scarcity.. To assess the risk of water scarcity, the methodologies of the WBCSD (Water Business Council for sustainable development) were applied, which indicated as a result that none of our operating plants are in water scarce areas.
Although our plants are not located in water scarce areas, currently the company has been actively participating in various commitments with the main actors on issues related to water management. By early 2014 the organization joined the CEO Water Mandate and began to develop the measuring of water footprint for operating plants, also incorporated internal campaigns to raise awareness of the importance of the resource among its employees. Additionally, Celsia participates in establishing policies related to zoning plans of macrocuenca Magdalena Cauca and the Pact for the efficient use in the hydropower sector. with Andesco.
Consumption and Efficiency in Water Use
The collection of water in the organization is mainly used for hydroelectric power generation. To achieve this, Celsia has environmental licenses and authorizations to use the water flow of the different basins where it operates. In some power plants, there is an ecological flow assigned by the environmental body. Control is carried out on this flow through meters to ensure its correct delivery. The organization does not harness water in areas with water stress according to The Global Water Tool, developed by the World Business Council for Sustainable Development (WBCSD).
EPSA has two hydroelectric power plants (Alto and Bajo Anchicayá) located in the Farallones National Natural Park, which the company supports by carrying out conservation and control activities.
In turn, for thermoelectric generation in the Zona Franca Celsia, in Barranquilla, water is harnessed mainly for the cooling processes, steam production and auxiliary sevices, taking water from the Magdalena River, which is recirculated in the process. Its surplus is returned with better quality, as to be used, it is subject to a physical/chemical treatment process ensuring its suitable quality.
In terms of efficient use and savings of water, the organization develops prevention actions, controlling losses in the hydroelectric generation systems, through the preventative maintenance of the water pipes and transport system to the turbines and with the change of spherical valves to prevent leaks.
In some processes, water used in power generation is recirculated to cool the machines. For thermoelectric generation, approximately 5% of the cooling water is recirculated. In this sense, in each one of the plants, Celsia's employees identify and constantly propose actions for efficient water use and saving. This process and those related to the use of the liquid are studied by the employees to seek saving opportunities. Additionally, the power generation plants have flow meters installed, which indicate the water being used in operations at all times. In addition, the installation was continued of sta¬tions to establish the hydroclimatic network which will make it possible to know the spatial and temporal behav¬ior of this resource in the areas of influence.
In 2014, Celsia carried out the purchase and transfer of property in high plains grassland zones from Corantioquia, Antioquia's environmental authority, contrib¬uting as such to the conservation of the water resource for the local residents and for the operation.
Meanwhile, with the aim of preserving and conserv¬ing the flows from the micro-watersheds that supply the main catchments, EPSA held reforestation days in the upper and middle parts of the reservoirs, covering a total of 193 hectares. Likewise, an agreement was signed with National Natural Parks of Colombia, whose objective is to strengthen conservation actions through processes of restoration and recovery of soils and the development of a training component with social participation in the Farallones and Las Hermosas national parks. This program relates specifically to the upper and middle reservoirs of the rivers that supply the Anchicayá, Amaime, Nima, Alto Tuluá and Bajo Tuluá hydroelectric power plants.
In addition, actions were carried out to conserve the flora and fauna in the territory of Calima El Darién, in partnership with Valle del Cauca Regional Autonomous Corporation (CVC, for the Spanish original), the May-or's Office, Inter-institutional Technical Committees of Environmental Education (CIDEA, for the Spanish original), National Authority for Aquaculture and Fish¬eries (AUNAP, for the Spanish original) and EPSA, achieving the following:
- An assessment of the state of coverage of springs and tributaries.
- Recovery of the forest protection buffer zone of the Quebrada El Vergel.
- Support for the government authorities in the development of the town aqueduct in the areas of influ¬ence of the Salvajina and Alto Tuluá power plants, and the improvement of water purification for the aqueduct that supplies the Prado power plant.
