storage alternatives on San Andrés Island, ColombiaDavid Garcés Córdoba, Opal Bent Regional Corporation for the Sustainable Development of the Archipelago of San Andrés, Old Providence and Santa Catalina, Colombia E-mail: dgarce@coll.telecom.com.co
Abstract We proposed and evaluated different options for a cistern of a „typical" house on San Andrés, Colombia, a very small island (27 km²) in the Caribbean facing Nicaragua's coast. On San Andrés, underground water supplies are very limited and the geologic conditions for storing surface water are not favorable. We have carried out an economic study for the different storage alternatives to determine the most suitable material for the construction of the cisterns, be they concrete, modular, polyethylene or wood. 5 people inhabit a "typical" San Andrés house. We calculate a gathering area of 75 m² and an optimal cistern volume of 20 m³. |
